Even brighter than H3 halogen lamps with 100W instead of the usual 55W
We used H3 LED lamps in a historic racing car at Le Mans 2025. As the headlight housing was too small, we had to cut it out in order to use the lamp, as these are naturally longer than normal halogen lamps due to the heat sink and fan. During the race, the heat sink with the fan was directly exposed to spraying water and rain. It was also subjected to extreme vibrations! I didn't actually believe that the lamps would survive even an hour, as they became so hot after just a few seconds that I burned my fingers. I am amazed that they survived the race under such conditions. Shipping was also very fast from China to Germany! It took just 4 days! The only improvement would be if the socket could be adjusted by 90°, as this would save us having to work out new centering points.
