LED headlight bulbs often look brighter than stock halogen bulbs, which is why many people choose to
upgrade their car's halogen headlights to LEDs.
However despite the popularity of this trend, come drivers find themselves disappointed with the results,
especially for the brightness. So in this blog, we will dig out the reasons why switching from halogen
headlights to LED bulbs may not always meet the desired outcomes.
Do you ever open your headlight bulb driver and saw these slione?
A potting silicone in car light LED driver power supplies is crucial for several reasons:
NO.1 | Unrealistic Lumen Value
![LED Headlight Bulbs : Unrealistic Lumen Value](/uploadfile/2024/06/18/202406181030040shdwG.jpg)
The Lumen of LED headlight bulbs refers to start-up lumens rather than stable lumens. This means that
the car LED lights have the highest lumens at the moment they are turned on. After a period of use, the
lumens will decrease, so you will feel that the brightness of LED car lights is decreasing
NO.2 | Higher Color Temperatur
LED headlight bulbs have a higher color temperature than halogen, sometimes it makes people feel that
the light is very strong and crisp, without the eye-comforting yellow light of halogen lamps
NO.3 | Low luminous efficienc
The luminous efficiency of LED lights is not high and the light brightness is insufficient. This is also
result in different light efficiency
NO.4 | Poor heat dissipation design
Excessive heat can degrade the performance and lifespan of the LED chips, causing them to produce
less light output. Additionally, high temperatures can lead to thermal runaway, where the LED's efficiency
decreases rapidly, resulting in dimmer ilumination and potentially shorter bulb lifespan.
NO.5 | Incorrect Installation
The installation steps for car LED headlight bulb are simple, but for some LED car lights that are not
plug-and-play designed, it will be difficult to adjust the light pattern. If the light pattern is not adjusted
properly, it will cause the light pattern to be very diffuse, not focused, and have dark areas.

In summary, the poor user experience after switching to LED car lights can basically be attributed to three types of reasons:
1. the LED headlight bulb itself
2. the incorrect LED car bulb installation
3. users are not adapting to the new lighting effects of LED bulb

(Improper Installation Leads To Scatter Light Beam)
As a manufacturer with more than 15 years automotive lighting experience, Unipower recommended to
choose T03 projector car lights, which deliver an efficient brightness of 55W 5000LM/bulb. These bulbs
offer consistent, stable high brightness without any concerns about light decay.
