I’ve been wanting such a product for quite a while, actually.
I use two 2700K bulbs and two 6500K bulbs (all CFL) in my bathroom to get good color rendering for makeup. No single color temperature shows me the colors well enough, but the combination is quite nice.
So, I’d like to get a similar effect from LEDs. Ideally, two or three shades in a puck light, or perhaps in a series of small, wall-mountable uplights. All chainable and plugged into a wall outlet.
