How to Find the True “Best & Brightest” H4 LED Bulbs?

Consider the Lux

Lux is the amount of light on a surface. A single lux is equal to one lumen per square meter. In other words, Lux is the usable light on the road. The H4 LED headlight bulb advertised as the “brightest” bulb doesn’t necessarily mean you will receive a functional amount of light on the surface. In general, the higher the lux, the more utilized light being turned into a usable beam pattern by the headlight housing. However, several factors should be taken into account when measuring lux such as the lumen amount of the bulb, the headlight housing, and the distance.


Beam Pattern

Beam pattern is the angle of the light coming from your car headlight which will decide if your LED headlight bulb is legal or not. A standard and safe light beam pattern should have clear cutoff light on low beam while maintaining a strong and uniform light on high beam. For safe driving, it is recommended to pick a LED headlight bulb like Max3 H4 to guarantee a perfect light beam pattern.


Choose the Right Color

The brightest H4 LED headlight bulb is white and approximately equivalent to 6000-6500K color temperature. Because the 6500K is close to daylight white which would be more visible for night driving. Click here to view the 6500K H4 LED headlight bulbs.


Have a Better Cooling Design

The only drawback of the LED headlight bulb is excessive heat they produce. The higher the power of the LED bulb, the more heat they generate.
