yeah i have a couple lights like that my new thorfire TG06 on high gets warm in about 2 minutes of use. We call these lights hand warmers...Thanks for the input people...the battery just gets warm, not to the level of being too hot to hold. The flashlight body however, if left tailstanding for 10 minutes (I use it ceiling bounce on max to illuminate a group photo) it does get unbearably hot to hold initially. I guess that's not such a bad thing as it would mean heat is being dissipated from the head throughout the body?
Most high power led lights will heat up very hot. All my xml and both my xpg2 get hot it is when one of these 300+ lumen lights don't make any noticeable heat you need to worry as it means the led are thermally isolated from the body of the light. The confined heat will eventually burn out the led or if the driver is good it will throttle.
an example of throttling is the fenix e99 ti or the fenix e05 2014 model will only stay in high mode for 3 minutes then kick down to medium.
