For those of you who love light painting, this could be really up your alley. There are lots of cheap led wands out there, but that’s the problem. They’re cheap. I have to rebuy the 10 dollar ones every year or so, and the batteries crap out quickly too. Recently I saw this super cool video on making an led wand. Now, my students have made baby versions of this in past Studio Lighting classes, but this is pretty sweet.
Of course, if you don’t want to bother with building anything yourself, you can buy one too, lol.
