Hi, is this (COAST HP14) a regular LED flashlight or is it very powerful/bright? It requires 4 AA batteries. Specs online: highest setting is 629 Lumens and 813 feet distance and on its low setting it is 52 Lumens and 219 feet beam distance. There are different modes; high, low, blinking and the beam spot is adjustable.
For 1 week, I shined this on my skin close up (about an inch away) moving around for several minutes on & off for multiple different days creating video content. Some of those days maybe 3-5 minutes and a few days for longer, maybe 10-15 minutes total close up. I think I remember feeling a little bit of heat, would that be from the visible light or the actual LED working, and Is this dangerous to shine on skin close? After that week, I never did it again.
Recently I read that Visible light can cause skin aging similar in the way UVA does but only if it is high/intense amounts of visible light (not low amounts from phones or computers). That made me worried. I don’t know the power or mw/cm2 of this, but it says online that flashlights are usually made from blue light. So I thought I’d ask here to see how powerful this LED flashlight is or LED flashlights in general?

It’s nice to see you, zooming!
629 lumens is moderately powerful.
Most of my flashlights are more powerful than that, but I tend to go for 1x18650 or 1x21700 flashlights.
I don’t think that a regular flashlight (like yours or mine) would cause very much, if any, skin aging.
An ultraviolet flashlight would be much more dangerous, especially for your eyes.
It’s normal for a flashlight to cause heat like that.

Coast/Led Lenser are consumer light as opposed enthusiast lights. Although they are excellent lights, would not worry too much about overheating.
