As a driver, you may be wondering what the difference is between a 2357 bulb and an 1157 lamp. While they may look similar, there are actually some key differences that you should be aware of.

These 2 bulbs are completely interchangeable because they both use a bayonet base. Moreover, they both have the same light output. So, in case you want to replace one bulb with another, you can do so without any issues.

Although both of these bulbs can be used for functions such as tail lights and turn signals, there are some differences between the two that make them better suited for different purposes. 2357 bulbs offer brighter output but have a shorter lifespan. 1157 bulbs feature better longevity but cost more upfront. So, let`s dive deeper into this theme.

Learn About 2357 Bulb

The 2357 bulb is a popular choice for drivers who want to upgrade their turn signal or brake light bulbs. These bulbs offer a significant increase in brightness compared to standard incandescent bulbs, making them more visible to other motorists.

One of the key advantages of 2357 bulbs is that they have a relatively low cost. You can find these bulbs for less than $10 per pair, making them an affordable option for most drivers.

However, one downside of 2357 bulbs is that they have a shorter lifespan than some other options on the market. So, in general, you can expect these bulbs to last for about 1,000 hours of use. This is still much longer than the average lifespan of an incandescent bulb, which is only about 500 hours. But, if you`re looking for a bulb with an even longer lifespan, you may want to consider another option.

The advantages of this bulb are:

• lower cost
• high brightness

The disadvantages of this bulb are:

• shorter lifespan in comparison to other bulbs.

Learn About 1157 Bulb

Now it`s time to find out more about the 1157 lamp. As we have already mentioned, this lamp is often used for turn signals and brake lights. It provides drivers with good light output and has a much longer lifespan than 2357 bulbs.

One of the main advantages of 1157 bulbs is that they can last for up to 2,000 hours of use. This means that you won`t have to replace them as often as other types of bulbs. However, this increased lifespan does come at a higher cost. You can expect to pay about $15 or more for a pair of 1157 bulbs.

To sum up, the key advantages of 1157 bulbs are:

• increased lifespan
• better light output

The disadvantages of this bulb are:

• higher cost.

2357 Bulb vs 1157 - Specs Comparison

OK, so you went to the shop and you have 2357 and 1157 bulbs in front of you. But what is the difference? 2357 bulbs are designed for single-contact sockets while 1157 lamps have dual contacts. The dual contacts allow 1157 to function as a brake light as well as a turn signal. However, this also means that 1157 will not fit into a socket meant for a 2357 bulb.

Brightness

Now you know that 2357 has a light output of 40 MSCP while 1157 has the light output of only 32. Consequently, light output is 25% greater on 2357 bulbs, making for brighter, more visible, clearer, and aesthetically pleasing light. In total, the 2357 lamp features 503 Lumens while the 1157 only has 400.

Heat Resistance

In this category, 2357 bulbs win out. With efficient heat diffusion features that resist heat damage, you can mount these bulbs in a wider range of locations on the car. On the other hand, halogen 1157 bulbs run quite hot - so hot they have been known to melt and distort plastic housings, lenses, and tail lights.

If you are planning on using these bulbs for extended periods of time or in a location where they will be 'always-on', definitely consider this before making your purchase. This difference may seem insignificant for some drivers, but in fact, it is a crucial safety consideration.

Nominal Power

As we have already mentioned above, the 1157 requires 2.1 amps while the 2357 only needs 1.7 amps. Consequently, the 2357 is more power-efficient, which means that it will put less strain on your car`s battery and electrical system. The 1157 has 27/8.3 Watts and 12.8/14 volts while the 2357 has 18/8.3 watts and 12.8/14 volts.

Use Cases

Finally, if you want to interchange these bulbs, pay attention to the socket type. If your car has a dual-contact socket, you could technically use either type of bulb. The only time you would need to be careful is if your car has a single-contact socket - in which case, you would need to use a 2357 bulb.

Beam Type

Of course, the beam type plays a significant role in the compatibility of bulbs. Thus, if the 1157 comes with a CK (clear/red) beam, it will be difficult to match it with the 2357, which has an Amber beam. In this case, the 2357 might not work as a replacement for your 1157 brake light. However, if you are looking for a backup or turn signal light, then the 2357 can replace either a 1156 or 1157 without any issues.

Color Temperature

The color temperature is also an important aspect that you need to take into account when choosing the right bulb for your needs. The color temperature is measured in Kelvin (K) and it indicates how 'warm' or 'cool' the light emitted by the bulb will be.

A lower color temperature means that the light will be warmer, while a higher color temperature means that the light will be cooler. The standard color temperature for halogen bulbs is between 2700K and 3000K. However, some companies offer 'whiter' bulbs with a color temperature of up to 5000K.

Which Lamp Is Right For Your Needs?

So, now you stand in the store and look at these two lamps already knowing their main similarities and distinctions. It is the right time to think about which one will actually suit your needs better. Here are some factors that you might want to consider before making your purchase:

• If you need a brighter light, go for 2357.
• If you are looking for a lamp with a longer lifespan, 1157 is your best bet.
• If heat resistance is important to you, 2357 should be your choice.
• If you need a bulb that can be used in a wider range of locations on the car, again, 2357 is the way to go.
• If you don`t mind spending a bit more upfront for a bulb that will last longer, 1157 is the right option for you.

So, as you can notice, the decision here is not that simple. You will have to weigh all the pros and cons of each option to make the best choice for your needs. 2357 bulbs typically outperform 1157 bulbs, but the latter is more affordable. 2357 bulbs won't break the bank, but they aren't as easy to find since they're not as popular.

You'll have an easier time finding 1157 bulbs since they're carried by most stores, and although less performant than 2357s, they're still a solid option price-wise. Thusly, whenever you are looking for a new lamp for your car, be sure to compare 2357 and 1157 bulbs before making a purchase!
