So basically, avoid light if you can. I'm a weirdo who spends most of my time in nearly total darkness so my toys don't really get exposed to light unless I'm taking pictures. Even during the day I have shutters that block out pretty much all light.
But then how would you get around displaying stuff without lights? I believe you're talking about direct/focussed lights, right? If one has to use, at all, which ones would be the best (LED?).
Also, you sound like a vampire! Is it anything to do with photography, if I may ask.
