Hey Guys, I need some advice from those more knowledgeable than me. I purchased 2 Sipik SK68 clones on eBay, one from TomTom and one from another Chinese vendor. I put a fresh 14500 battery in each. The TomTom clone runs normally, but the other clone gets really hot,really fast (almost too hot to hold). I thought all these clones were manufactured in same factory. Why would one of them run so hot? More importantly, is this light dangerous to use?
Thanks
Can you check the lights and cells currents? Maybe one cell is better then the other?
SK68's are not dangerous when used as intended. :)
Possibly better application of the TIM between the LED and the body thus transferring more heat to the body in the one that gets hotter? My only thought.
Probably no TIM under the star (I guess no TIM in both of them)... The LED may die soon.
A fresh 14500 is not good for sk68. Too much current (more than 2A).
If you can not measure current, try at least to compare light output and runtime.
Thanks Guys, Two questions, what is TIM? and is the LED burning out the worst that could happen?
In other words, No Kaboom!
Thermal Interface Material.
Is it possible the flashlight is short circuiting? Or maybe the driver is not working and is dumping to much current into the LED
The ones I got from eletrading only had a piece of paper between the led star and the body.
Also with a fresh 14500 it draws 2.2A which is probably way to much for it to handle.
