A completely unfair comparison between the LED Lenser M5, the Fenix TK41 and my $10 homebuilt 100W LED flashlight.

You will need a big pocket for that thing.
How do you keep the led from over heating
You're applying 36 volts instead of 34, be carefull because that LED it's giving white-red light, and that's becuase it's burning out
O-O you should call it Day-light ;P
I'd love you see you upgrade it further to encorporate a reflective surround like the hand torches, see how bright a spot light it would make!
How can you call it $10 when the batteries are at least triple that each?
with a reflector, proper lens and adequate heat management that lamp will be good for stage and movie sets.
lol I love the last one 🙂 this is my 100 watts flashlight and…. Oh!! 🙂 awesome! I need to build one now 😉 Cheers
You mentioned the batteries have to be ni-cd batteries. Why can they not be li-ion? Ive got plenty of Ryobi 18v li-ion laying around but not ni-cd.
Thank you for braving the cold weather for science.
love to tinker
