My new Olight M10 runs hot - is it safe?

Hi,

I use torches for photography - I paint with light using the torch.

I bought this torch on a recommendation and it is excellent. However, unlike my lenser P7 it runs quite hot. Not hot enough to burn uncomfortably warm.

It came with an Olight battery, a CR123A and I was wondering if

a Is it safe? Is running hot normal - on full power?
b Is it worth trying a new battery?
c I'm a total newbie to torches and batteries really - is a CR123 the same as a CR123A? And which brand is most reliable?

This is my first post to candleforums, fingers crossed I'm in the right place and haven't trodden on any toes

Thanks for any help

a. Yes. White LEDs are something like 40% efficient (~120 lumens per watt), ten times better than filaments. But the other 60% is heat, and 60% of a few watts is a couple of watts.
b. Yes. You might break the bank on CR123s. Some rechargeable options may exist. I suggest you avoid Ultrafire rechargeables.
c. Yes, they are the same. An RCR123 is a rechargeable almost-CR123-sized cell. It will usually have higher voltage, possibly enough to cause a problem.

Many thanks for helping me out with this.

I have just checked out a video on youtube on the safe use of cr123's. Very helpful.

Getting wiser all the time

Cheers
