Hello everyone,

While I have been into flashlights for a long time I have never been into modding them.
Recently I have seen several pic of flashlights with after glow mods which look pretty cool.
Have seen a video of someone using strontium aluminate mixed with epoxy places on the LED board behind the optic of a flashlight.
I was thinking about getting an Astrolux S43 and giving this a try but was concerned how the epoxy would cope with the heat generated or if it would damage the board in any way.
Sorry if this is a silly question mechanics is my thing normally not electronics
Thanks

Generally the LEDs will never get above 85C. It is possible for something highly concentrated light to get hotter than that but the heatsink and body will always be under 85C. Most expoxies can handy that fine. The strontium aluminate is a refractory ceramic and is good up to 1000C.

So go for it and share pics :)

It works fine, have fun with the experiment!

This is a quad, with a FET/ direct drive engine. generates plenty of heat
