About the long throw, point well noted thanks. And you've now got me concerned about the heat up issue. I dont know if you've noticed, but ive deliberately left open space in front (to let in fresh air) + i only switch it on when i'm riding. So i reckon even if those tiny heat sinks are not able to keep the temtrature under control, then the fan would do the trick. Even if somehow the LED manages to heat up, there should be enough air flowing through the body in the first place to keep it all nice and cool. Kindly have a look at build structure and please let me know if u still think heating may be an issue worth stripping down my light ... again
