i did a quick search on this forum based on “hold hot”
And it returns a number of people complaining about how hot the flashlight becomes.
Have a new SkyRay King, COOLEST light ever!! I had been using lousy Ultrafire Ebay batteries that I found out are only about 700 mah batteries. Got some better ones that are rated about twice as much, and have some of the Trustfire Flames coming in the mail also.
If you leave the light on for an extended period of time, will it get hot enough to damage itself? I ran it the other day with my Ultrafire 2400’s to see how long it would run, and after 20 minutes it was almost too hot to hold in your…
Maybe it’s the hype around this light. Maybe I expected too much but when I went outside and compared it to my TK75 or BS Terminator it just doesn’t seem to amaze.
The light output is great. It’ll light up a room just fine. It hurts if you flash yourself in the face but outside it just seems to be lacking.
The light itself gets sodding hot on turbo - as expected - and it’ll trip the protection on some Ultrafire flames (they actually get about 2800mAh capacity so I’m keeping them) but I just do…
IMO ya got a light that ain’t worth a poop regardless of every other wonderful thing ya wanna say about it. I equate it to cars. For instance, if ya got a brand-new Rossa 12 cylinder Ferrari that after a mile of rapping up rpms through the box like the motor was designed to do, then the thing overheats everytime no matter what ya do, what do ya got?
Ya got basically a useless POS ride IMO.
I’m only impressed by hot-rod lights that can run turbo and not burn up, or fry your hand so bad ya can’t…
I have a question on safe temperature ranges for small xpg and xml lights running on high(1.4-3.4 amps at the tailcap). With good heat transfer to the host, what would be the highest safe external temp before damage to the emmiter? I have a Romisen T601 that gets VERY hot on high, over 120F in just 4-5 min. from 75F.
I also posted a link to the manufactures documention on a 400$ flashlight that gets to hot.

Based on the running time and thermal management system of real-time temperature detection. When the flashlight is on high brightness mode, the first 5 minutes the output will keep full brightness. In the subsequent 5 minutes, the output will gradually drop to 50% of the initial brightness.
And previously mentioned i have a real 8 watt LED and it gets to hot to hold.
Sooo heating is a real problem … well it is to me. At the very least the cooler you keep the light the more output you’ll get so that alone is a good reason for some good thermal managment
