LED Lightshow

So, sure, LEDs uses less power, makes very little heat, and virtually never burn out—a pity about that eye-punishing blueish-white glow, though. How about an array of red, green, and blue LEDs that mix to make practically any color? That’s Color Kinetics specialty: a company that has pioneered LED light mixing in signage and display design. In addition to many form-factors for the lights themselves, controllers allow programmed color sequences for all kinds of effects. Wow your guests in the salon as the lights fade from sunset reds to moonlight blues… A caveat is the need for 24 volt power, but if you can afford something like this, you ought to be able to spring for a 12 to 24 volt converter, too.
