The brightness increase, + 300%, in lumens indicated compared to a halogen is a parameter calculated with REAL data with an ULBRICHT sphere.

The choice between a 4000K (neutral white) and a 6000K (cool white/bluish) LED bulb for your car is not just a question of aesthetics, but above all of safety and the physics of light.

This is why, for conscious road use, the 4000K shade is often considered superior:

1. Better visibility in adverse conditions

• The main advantage is the performance in rain, fog or wet asphalt.
• 6000K: Very cold light tends to reflect off water particles and the shiny surface of wet asphalt, creating a "white wall" effect or return glare.
• 4000K: The warmer component of light penetrates haze better and is absorbed less by the dark, wet road surface, allowing you to see the outline of the road better.

2. Less eye strain

• The human eye evolved to see best in natural sunlight (which at midday is around 5000K).
• Too bluish a light (6000K+) forces the eye to work harder to focus on contrasts, tiring the eyesight during long night journeys.
• 4000K offers a more natural contrast, similar to high-quality halogen lamps but with the power of LED.

3. Color Rendering Index (CRI)

• LED lamps with extreme color temperatures often sacrifice color fidelity.
• With 4000K, the colors of road signs and obstacles are more realistic.
• At 6000K, everything tends to turn grey/blue, making it more difficult to distinguish details at the edge of the road.
