Too safe….probably yeah maybe, and that’s fine. A lot of this anti-heat stuff comes from the general lighting industry, notsomuch the flashlight folks (obviously…I mean it was light geeks that pushed envelopes and made cool things despite some heat, and eventually the world followed…most of the world).
Many lights will limit or prevent hot-hot running temperatures either through limiting the current altogether or by using a timer or temperature reading on the driver which then bumps it down to cool off. Choose a light or build using a driver that has no limits and yes, you can actually blister your skin and in some cases damage components, depending. Most people will turn the light down or off when it gets pretty hot, and turn it off in a panic if it feels super hot, but generally the emitters and electronics can handle temperatures far above the point where you skin can actually get burned. Ultraviolet emitters and some others are exceptions…heat wimps. Super cheap lights with plastic reflectors or other unworthy parts may be damaged if they are modded to run high power fun.
I had a chuckle yesterday at work. Coworker isn’t a light geek but he loves lights and got into them many years ago when lithium cells were less easy to come by. He’s been using Lumintop Tools for awhile but usually just quick utility bursts of light. He left one running on high on his desk for awhile and was shocked when he picked it up again - thought his hand was going to melt off. lol. I picked it up and was like, yeah, it’s warm, almost hot, but not really hot yet. Uncomfortable to hold, but doable without skin turning red. So it’s relative and it takes some exposure to realize what’s “hot” and what’s actually hot, and where those limits are. But other than skin, the light and components are usually plenty robust.
Mainstream light makers will prevent this heat in favor of longer run times and/or avoiding complaints in the mass market customers (that’s a win-win for most general public light users, notsomuch for enthusiasts).
