3157A Vs 3157Na: Which Bulb Is Better?

The 3157A is a standard incandescent bulb. It produces a yellowish light and has an average lifespan of 750 hours. The 3157Na is a compact fluorescent bulb, which means it uses less energy than its incandescent counterpart. It also lasts up to 10 times longer than the incandescent version at 12,000 hours! Keep reading for more information about these bulbs! 3157A vs 3157Na: which one are you going to choose?

The incandescent version is more popular, but the compact fluorescent bulb lasts longer and uses less energy. Both bulbs will be pretty similar in appearance! They can both fit into any standard socket, so don’t worry about those differences. However, they have different properties that might make one better suited to a specific task than the other.

3157A Vs 3157Na: What Are They?

The 3157A bulb is an incandescent light bulb that comes in the shape of a lamp. It has a bayonet base and can be screwed into any socket. The 3157Na bulb is the same thing, but the difference is that it does not need to be screwed into a socket. It has an attached cord that does not have a metal contact at the base.

This makes it free to be plugged in and turned on without the need for any incandescent light socket. Both these products are used in decoration lighting, either for cars or home use. They are mostly found in wall cabinets, ceiling fixtures, or anywhere you wish to attach the light.

The 3157A and the 3157Na bulb both have a very similar shape, but they are not interchangeable. They look alike, except that the cord attached to the base of the Na branded bulbs is missing from A branded ones. The wire used in making these bulbs makes them suitable for decoration lighting.

The 3157A bulb contains 260 pieces of small, cylindrical light bulbs fused to form a single lamp. It has a plastic or glass covering at the top through which you can see all these little cylinders. These lamps are made using tungsten wires, and they do not give off much heat. The Na branded bulbs only use the wire to light up and contain no glass covering at all.

These two bulbs can be plugged into a multi-socket to form a multi-colored lighting system, but they cannot be used for household lighting. They are incandescent lamps that need much more voltage than normal filament lamps, which makes them unpopular. These bulbs might be energy efficient if used properly, but they still produce a lot of heat and are not suitable for regular use.

3157a vs 3157na

They are mostly preferred by people who wish to decorate their house with lights and give it a festive look. These bulbs may be better than traditional lamps because they contain no filament, which makes them last longer. Using these bulbs also cuts down on the usual wastage of energy.

The 3157A bulb is mainly used for car decoration lighting and can be a part of your lighting system if that’s what you wish to have. They are available online as well as in general stores relatively cheaply. However, the Na branded bulbs only function as decoration lights because they contain no cord attached to them.

They are mostly used for car decoration, their primary use being for lighting up the back seat or under-the-seat area of your vehicle. These lights have a limited lifespan and so their burning time should be strictly monitored. Since they contain no filament, they are not affected by wear and tear but can only work for a year or so.

These bulbs can be costly if used excessively because they consume more power than filament lamps and require frequent changing. They are also widely available online as well as in general stores, at around the same price. You can even find these bulbs on sale sometimes if your need is great, but they will still cost you a decent amount.

These bulbs are meant for decoration and not regular use, so they need to be used responsibly. They can light up your room or car instantly and provide sufficient lighting, but you will have to deal with the excessive heat released by these bulbs during their functioning.

There is no doubt that these lamps serve a purpose, but they still need to be used with caution and only when the situation demands it. They can provide you with a great choice of decorative lighting options that can brighten up your house or car in no time. However, these bulbs require regular maintenance as well as replacement frequently.

Online stores will have them available at cheaper rates than local ones, and they can be bought easily and put away for future use. These lamps can be used for decoration, but they need to be treated and handled with care and kept only in designated areas.

They should not be used near combustible material or where people might accidentally knock them over because the glass vessels inside them are fragile.

3157A Vs 3157Na: The Similarities

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 29

When it comes to 3157A and 3157Na, there’s a lot that is the same. For example, both types of bulbs are typically used in desk lamps and other small fixtures.

Both use an A-line filament design which produces light with less glare than other designs. And they’re both available as either screw-in or bayonet bases for easy installation.

Finally, they both provide a similar level of illumination. Both are relatively easy to install, and the most beneficial part of using either one is reducing your environmental impact. Finally, both bulbs contain mercury.

3157A Vs 3157Na: The Differences

The 3157A and 3157Na light bulbs are two of the most common types on the market. The former is a standard incandescent bulb, while the latter is an environmentally-friendly halogen type that lasts much longer than other varieties.

Both have their pros and cons, so it’s essential to know which one you’re looking for before making your purchase.


3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 30

The 3157A is the same Phillips bulb that’s been around for years, but with one difference. The “A” stands for amber color because it gives off a softer yellow hue than traditional light bulbs.

If you want to replace an old, existing bulb in your car or home, this is what you’re looking for. It’s very much like the standard 3157 bulbs in every other way.

The 3157Na stands for “natural,” and it’s a little more expensive than its predecessor. The price tag is because it lasts up to three times longer, although light color and brightness remain the same.

Gas Mixture and Price

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 31

The 3157A incandescent light bulb has a warmer yellow hue compared to the 3157Na natural halogen bulb. The latter emits a whiter light and is a more energy-efficient but much more expensive choice.

The difference between the two bulbs has to do with the gas mixture used in each one. 13 milligrams for the A-type vs. 6 milligrams for the N-type.

The 3157A contains mercury, which is something you want to avoid when making an environmental impact. However, it makes up for it by lasting longer as well as being less expensive.

The 3157Na does not contain mercury and will last longer than the 3157A but at a higher cost.

3157A Vs 3157Na: Which One I Should Buy?

Life Span

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 32

Firstly, while both have a lifespan of about 1 thousand hours, there’s a 10% difference in brightness when comparing them side by side.

The 3157A is a standard incandescent bulb, and the 3157Na is an LED. The life expectancy of an LED bulb is also typically much longer than that of other types, which saves you money in replacement costs over time.

The 3157A comes with a CRI of 82 and an average lifespan of 20,000 hours, whereas the 3157Na has an 80 CRI and 25,000 hours.

For those reasons, as long as you don’t mind a whiter light and doing the occasional replacement for this type of bulb, it is worth going for the 3157A.

However, if your priority is to save money without worrying about replacements too often, go with the 3157Na.


3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 33

So what is the difference between these two? The answer lies in their filaments: A-bulbs have tungsten wire while Na-bulbs have sodium wire.

Tungsten gives off a whiter light than sodium, so A-bulbs tend to be more yellow than Na-bulbs.

They also burn at a much higher temperature. But the downside to tungsten is that it melts quickly, so A-bulbs have to be carefully handled by trained professionals because they will overheat and break if you look at them wrong!

Sodium wire doesn’t require this kind of care, but it has a limited lifetime and a lower wattage.

So which one is more powerful? Na-bulbs were rated to use 50 watts at 12 volts, while A-bulbs used 42 watts at the same voltage.

This would be like your car battery started at 40 amps and then only at 30 amps when you used a Na-bulb. It’s a huge difference, and it shows how much more efficient sodium bulbs are.


3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 34

The reason that A-bulbs have such a lower wattage is the conservation of energy. When electricity flows through the filament of an A-bulb, it isn’t all used up in lighting the bulb.

Much of it is given off as heat, and the filament has to handle this, or it will burn out. That means that A-bulbs need a higher wattage because they have to dissipate more power without breaking.

It has been said that 60% of the electricity consumed by incandescent lights goes out the window since these lamps give off heat rather than light. This makes them the least energy-efficient bulb type.

Na-bulbs, on the other hand, use the same energy to make light and heat. This means they can use a lower wattage without breaking down.

So if you want to go green and save energy while still using your headlights at night, it might be time to switch from A-bulbs to Na-bulbs!

Color Temperature

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 35

People often hear about color temperature and wonder what it means.

Color temperature measures how much red or blue light is in the white light produced by an electric lamp, with higher color temperatures indicating more incredible amounts of blue content.

The 3157A bulb has a rating of 2700K to 3000K on the Kelvin scale, which falls into the ‘warm’ category that produces yellow-white light similar to candlelight or sunlight at noon.

A rating under 2000K indicates redder than blue content and gives off a bright white appearance like daylight at sunrise or sunset.

The 3157Na bulb has a rating between 4000K to 5000K on the Kelvin scale, which falls into the ‘neutral’ category that produces a color similar to daylight at midday.

A rating of over 5000K falls into the ‘cool’ category and is usually used for car headlights because it increases visibility against road glare.

Therefore, here is some advice from us. Firstly, be sure to consult with someone who knows about color temperature before deciding which one would look best in your room or home.

Due to its lower color temperature, the 3157A gives off a much warmer light than the 3157Na bulb. This makes it better suited for usage in the living room to bring a relaxed feeling or as office lighting where you want less harshness.

The 3157Na bulb gives off a neutral light, which allows it to be used as a substitute for sunlight and is therefore often recommended by doctors and physiotherapists.

The light emitted by 3157Na can be more pleasing to the eye than other bulbs because it emits a softer glow. This means less glare and fewer headaches.

What’s Available In Your House

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 36

3157A is incandescent, and 3157Na is compact fluorescent (CFL).

This means that if you currently have CFL bulbs in your house, then switching to an incandescent bulb will require some changes, like changing out all your fixtures because they won’t work with this new kind of bulb.

If you have incandescent fixtures in your house, then the 3157A would be the best choice for you. However, if you are looking for an energy-efficient lightbulb that can fit into any fixture, the 3157Na would be best for you.

Environment Effects

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 37

The 3157A sodium bulb produces a yellowish light that casts the surrounding area in a warm golden glow. It is often used to create an atmosphere that is both inviting and relaxing.

The 3157Na, however, provides a whiter form of light that does not have a yellowish hue. This type of light is often used for illumination because it does not have the same atmospheric qualities as the 3157A bulb.

Artificial lighting is a common source of both energy consumption and environmental effects.

It is crucial to consider the 3157A Vs 3157Na lightbulb environmental effects when deciding what light bulbs to use in different settings.

Residential lighting can have a significant effect on the amount of energy used in a house. It has been shown that when sodium bulbs are paired with motion detection, brightness can be increased without affecting energy use.

Additionally, these lightbulbs types have also been known to have fewer health effects than other types since low levels of pollutants are emitted from the light source.

In contrast, fluorescent lights have been found to cause migraines and other health issues due to the flickering effect caused by magnetic ballasts.

These are significant differences in environmental effects between 3157A Vs 3157Na lightbulbs. To make a substantial impact on the environment, consumers need to consider their options when making lighting choices.


3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 38

There are a lot of factors that go into the brightness of a lightbulb, such as voltage and current.

The 3157A is a halogen lamp with an average light output of 2400 lumens, while the 3157Na is a high-pressure sodium lamp with an average light output of 2000 lumens.

In general, the 3157A provides higher output than the 3157Na as it uses more power. The difference between these two bulbs is minimal as they both operate at their respective target voltage and current for their type.

Spectral Output

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 39

Another factor to consider is the spectral output of these bulbs. Sodium lamps are ideal for applications that involve reading, writing, or viewing documents as they have a high-intensity light in the yellow spectrum.

On the other hand, Halogen lamps provide a more natural lighting environment with their red-orange color temperature. For this reason, halogen bulbs are typically used in applications where color rendering is essential.


3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 40

The size of a lightbulb affects the amount of light it produces.

A larger bulb will produce more light than a smaller one, but depending on how much lighting is needed for the given area, you may need to consider other factors like energy efficiency or cost.

A 1357A (the most common type) is about four inches in diameter and provides 2200 lumens, enough for most indoor spaces.

The 1357A is used in projects that require a more powerful light source, but it cannot be connected to most fixtures.

It uses more energy than the 1357Na and emits more heat, making it less energy efficient.

A 1357Na bulb is about two inches in diameter, producing the same lumens as its larger counterpart.

The smaller size allows it to fit more easily into standard household fixtures. However, it also emits less light, and some find the light produced by this bulb too harsh for home use.


3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 41

Most people would instead go with the 3157Na as it has a higher CRI, but that is not always the case. While it is true that a high CRI will allow you to see more colors, there are many other factors involved in what makes a light bulb better or worse.

The 3157A emits a warmer and softer light than the 3157Na, so if you have children or pets scared of the harsh lighting of most LED bulbs, then the 3157A might be the right choice for you.

Now that you know the differences between CFLs and LEDs deciding which one to buy is up to you!

If you want a bulb with a high CRI for performing color-sensitive tasks, then go with LEDs. However, if the price is your main concern when buying lightbulbs or needing something brighter, you should go with CFLs.

Why Do People Decide To Switch From 3157A To 3157Na?

The 3157A is a more common type of lightbulb that is present in most households. The 3157Na is an LED lightbulb that has been designed to replace the 3157A.

The 3157Na is more energy-efficient and has a longer life span than the regular lightbulb, saving money in upfront costs and energy usage. With these benefits, it is no wonder there are many pros to switching to the LED lightbulb.

Save Electricity Bills

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 42

One of the most significant benefits of using the 3157Na rather than regular bulbs like the 3157A is that LED bulbs use less energy and cost less electricity.

The operating costs can range from $1.00 for the first year to $7.00 for the sixth year, depending on electricity rates.

The average household could save up to $60 per year by switching from incandescent lightbulbs to LEDs. This is a significant amount of money that can be put towards other bills or savings for younger families.

Longer Lifespan

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 43

The 3157Na also has an extremely long lifespan estimated at over 30,000 hours.

This means that if someone were to leave their lights on for 10 hours every day of the year, they would only have to replace the LED lightbulb every few decades, saving time and money in maintenance costs.

For example, changing a bulb with incandescent bulbs can be a two-person job, and the new lightbulb can range from $3 to $15. This is such an easy task that eradicates most of the benefits of switching to these lights firstly.

However, there are still some issues to switch from 3157A to 3157Na if your house still has the incandescent bulb system.

Some Issues

3157A Vs 3157Na
3157A Vs 3157Na: Which Bulb Is Better? 44

One of the most significant issues with LED lights is that they are unavailable in most common household bulbs.

Therefore, most people do not have experience using them. With the use of 3157A lightbulbs, most people are used to turning off a certain number of lights when leaving a room or going to bed.

For example, most people only use one overhead light in their bedroom and turn off all other lighting sources.

If this person were to switch from incandescent to LED bulbs, they might be more inclined to keep all lights on in their bedroom because they do not have a specific visual cue for turning off the light.

This is where there are some adverse effects of using these 3157Na lightbulbs rather than regular incandescent ones.

The most common area for these lightbulbs is in the bathroom, where many people like to read or finish the grooming before bed.

If the family were to switch from an incandescent bulb to an LED one, they might not see when doing these tasks at night.

This could lead them to keep other light sources on in their bedroom, leading to the increased cost of electricity.

However, we can conclude that LEDs are a better choice for your home because they save you money in the long run and are better for the environment.

3157A Vs 3157Na: The Benefits Of Each Type Of Light Bulb

3157a vs 3157na

There are a few different types of light bulbs to choose from. The most popular bulb for both residential and commercial purposes is the LED light. However, many people prefer to use incandescent lights, halogens, and CFLs over them due to their low energy consumption and longevity.

One of the most popular bulbs is the 3157, which can be found in both halogen and LED varieties. At first glance, it may seem that they are both the same, regardless of their type. However, when you study them a little further, you will find quite a few differences between these two types of lights. This part seeks to highlight the benefits of each light bulb.

3157A Light Bulb

The 3157A light bulbs are incandescent ones with a base classified as an S14 medium Bipin. The 3157A bulb has a halogen gas-filled tube in its center, making it very efficient in terms of the luminosity and heat it generates compared to other types of incandescent lights. The life span of the 3157A bulb is about 2,000 hours.

They are also available in a variety of color temperatures, depending on the amount of heat generated. The most popular 3157A light bulbs have three different color temperatures that can be selected from, with 2700K being the warmest and 3000K being the most widely used.

3157Na Light Bulb

The 3157Nas are most commonly known as ‘194s’. The base of this light bulb has a smaller pin diameter compared to the 3157A type of bulbs. It must be noted that both the halogen gas-filled tube and the base of this light bulb are smaller than those of the 3157A type. This particular light bulb has a life span of between 1,200 and 2,500 hours.

However, the light produced is far less than that of the 3157A bulb. Most of these bulbs are manufactured in China and Mexico. The color temperature varies from 3000K to 5000K, with most people preferring low color temperatures such as 3000K and 3500K. Many feel that it is a good choice for many households due to its low energy consumption.

3157A Vs 3157Na

When comparing the two light bulbs, it is essential to look at the life span as this is one of the main advantages of using them. This has been discussed earlier, and we can rest assured that both bulbs have a long lifespan compared to other kinds of lights.

3157a vs 3157na

However, you should also consider the amount of energy the bulb consumes before making your decision. For example, the LED version has a lower voltage of fewer than 24 volts, which also consumes less energy.

The base of these bulbs should also be considered before buying them. This can be easily determined by looking at the pins of the light bulb. For example, the 3157Nas have smaller pins compared to the 3157A type of bulbs.

This would make the 3157Nas more desirable for applications where you want to use them with a switch without any issues. For example, they are ideal for dimming purposes compared to the 3157A type of bulbs. You should also consider that they are used for different vehicles, including cars and trucks, which means their applications are different.

3157A Vs 3157Na: Which One Should You Choose For Your Needs

Each of these is made with differing materials, and the result is that they each react differently to different types of exposure. 3157A is made with Astatic Acrylic. 3157Na, on the other hand, is made with Neoflon Isotron.

The difference between the two materials will have a lot to do with how they are affected by different types of exposure. For example, 3157A may be less likely to change color if exposed to ultraviolet light, while 3157Na may tend to lose its color when exposed this way. This will depend on how it was created, but there will be similar results for both products in many cases.

Overall durability can also come into play as well. The two can also be affected by exposure to oxygen, ultraviolet light, and ozone. Because 3157A is made with different materials than 3157Na, it will likely stand up better over time to the type of exposure that would affect this product more often.

3157A vs 3157Na: which one should you choose for your needs? The key to figuring this out is knowing the type of exposure that it may be subjected to. This will impact how durable each product may be, and in many cases, there can be different results for both products depending on these factors. If you know the types of exposure that need to be considered, picking one or the other becomes much more accessible.

For many people, 3157A is a better choice because it can stand up to exposure much better.

3157a vs 3157na

3157A Vs 3157Na: Why Use The Other Type If The Other One Doesn’t Work Well Enough

The 3157A and 3157Na are both sodium dithionite (SDT). It is a compound that is typically used to make water safe for drinking. The difference between the two, however, is one of their properties. Hydrogen peroxide (H2O2) is added to make the SDT more effective. This results in the production of hypo-chlorous acid (HOCI), which has oxidizing capabilities.

The HOCI has more potent disinfectant properties, but it loses its effectiveness over time. The 3157A is cheaper than the 3157Na because it does not require the addition of a peroxide solution. The 3157A is still effective at oxidizing bacteria, but H2O2 may be used to recharge its effectiveness.

You might want to use the 3157A because it acts as a more complete oxidant than the 3157Na. The two types of SDT react differently to pathogens, but they are both effective at killing them.

However, the main difference is that while NaDTC has an additive effect on killing pathogens, the 3157A works synergistically. The oxidizing action of the 3157A will be much stronger when it is combined with H2O2 than when used without it.

The main reason you might want to use the 3157Na instead of the 3157A is its effectiveness in terms of cost. The 3157A works more effectively than the NaDTC, but it is also much more expensive.

If you want to use SDT to clean water and make it safe for drinking, you might want to use a “combo pack” of sorts containing both types of SDT. The ORP levels will be higher if you use both types, which will make the water more suitable for drinking. The 3157A has a lower ORP level of around -200mV, while the 3157Na has an ORP of around -170mV.

An alternative way to think about your answer is that if the paper does not work well enough, you could find another type. If the paper doesn’t work well enough, you should use an alternative kind of SDT. The 3157A has better oxidizing properties than the 3157Na, so that it would be a better choice for this situation.

3157A Vs 3157Na: How Long Will Each Last Before Needing To Be Replaced Or Turned Off

Both of the 3157A and 3157Na bulbs have a lifespan of 2000 hours.  After the bulb has been on for 2000 hours, it will need to be turned off or replaced. The 3157A will last a little longer than 2000 hours, but it shouldn’t be used continually after being on for 2400 hours.

3157a vs 3157na

However, the 3157Na bulb is designed for extended daily use and can be left on for up to 4000 hours. This means that after being turned on for four days in a row, it should be turned off.

Which Has A Higher Wattage And Which Needs To Be Replaced Or Turned Off Sooner

The 3157A is designed for use with 12v/12w vehicle applications. The more common bulb for this application is the H3 found on some car models and pick-up trucks. It takes about 50 watts to operate. The 3157Na is designed for use with 12v/70w vehicle applications, usually found on a car’s fog light or driving lights. It takes about 35 watts to operate.

The 3157A is a halogen bulb and takes around 30 watts, while the 3157Na is a high-intensity discharge (HID) bulb and only takes about 28 watts. The H3 uses 12v, 50 watts max, while the 3157Na uses 12v/28w max. Both of the bulbs have been designed for certain specific applications.

Which Is Easier To Install Or More Expensive

Both of the bulbs can be found online and in some local auto part stores. While the 3157Na is more expensive than the 3157A, it will last longer and perform better, so the cost may be worth it. Another advantage of using the 3157Na is that you will not need to recharge it, whereas, with the 3157A, you will need to purchase a peroxide mixture and add it every couple of months.

The main thing that makes these bulbs different from each other is their ability to generate light without adding anything. The 3157A bulb must be added to a peroxide mixture for it to work, whereas the 3157Na is ready to go right when you take it out of the package.

The 3157A is designed for lower wattage applications and can be used on both cars and boats, while the 3157Na is designed for higher wattage applications found mostly on marine vessels. The 3157A is less expensive than the 3157Na bulb, even though it needs to be replaced every few months.

The only thing that might make someone need a 3157A and not the 3157Na would be if they could not find the Na version anywhere. Otherwise, the 3157A is designed for use on both cars and boats to be used in low or high power applications, including home appliances.

3157a vs 3157na

The 3157Na only comes with a 12month warranty, while the 3157A has a 24-month warranty, which gives us more confidence in purchasing the 3157A over the Na D4S (3157A). Even though the 3157Na is longer lasting and has higher performance, its shorter warranty makes it a less viable option.

3157A Vs 3157Na: The Difference In Cost Between The Two Bulbs

3157A and 3157Na are two bulbs for use in place of traditional lightbulbs. While they both produce different levels of lumens, the main difference between the two is cost. The 3157A bulb costs $0.33 per 15 watt-hour and can produce up to 1001 hours of light, while the 3157Na bulb costs $0.72 per 15-watt hour and can produce up to 1127 hours of light.

While both of these bulbs can produce similar lumens levels, an individual will need to weigh the cost difference and choose the bulb that makes the most sense for their needs.

In economics, the law of supply and demand states that consumers will purchase a good if the marginal benefit outweighs the marginal cost. In this case, as the price increases, the quantity demanded decreases. In other words, as the price of a good goes up, people will buy less of it.
