Interesting. Would like to see how this performs. Surprised that there are no lumen claims on the listing. 3- 18650’s hanging off the back of my head sounds a little heavy though.
It says:
This light arrived broken. White light would not turn on at all while red and blue do work. The Red and blue feature is not useful to me so this light has no value to me. I contacted seller multiple times and never received a response.
Probably the plastic casing would melt down right into your eyes.
Look on the bright side , during winter your car refuses to start you just open up the hood and give the engine a good shine and everything in there gets real warm and cozy.
