AUTO BILD test process:
The AUTO BILD lamp test was conducted on 12 different D2S type xenon lamps in the price range between €8.50 and €210. The testers put brand name manufacturers, as well as No Name products under scrutiny. The lamps were tested according to ECE Regulation R99 for gas discharge lamps at the Dekra lighting laboratory in Arnheim in the Netherlands. Luminous flux and light distribution on the road were evaluated using various test points with Valeo headlamps in a Renault Mégane.
The key point in the process was "Point 75R" – this lies 75 meters in front of the vehicle on the right-hand side of the road. The brighter the light at this point, the safer the driver will be.
