EX10 Heat issue?

[Tec40]

I was wondering why my Romisen A4 II NW,does'nt get as hot in high mode as my Nitecore EX10? Does anybody know why?

Better heat transfer - Romisen isn't as good and keeps heat inside (and fries the emitter).

Oh WOW!! That's not good!! My EX10 will get pretty dang hot after being on for about 10 minutes. The Romisen gets warm,but I'm still able to handle it,after the same amount of time. That sucks! I like the Romisen better for that reason. So I guess my EX10 will last much longer because it gets much hotter??
