They can be controlled by computer to change color temperature at will, come on when you take a step or walk in a room, they can be put almost anywhere because heat is not a factor. LED lighting can be run on low voltage circuits or batteries.
LED lighting is going to change how we think about lighting.
Have you played with these? ;-)
Maybe I’m confusing LED lights with something else, but there’s a certain type of car headlight that is bluish-white and extremely bright, and I think they are blinding to oncoming drivers and very dangerous. I had some Christmas tree lights with that same blinding bluish white light, and threw them away. They had no softness at all and just didn’t look right on a Christmas tree. But I love LEDs on flashlights because what I want with a flashlight is brilliant, short-term illumination, not an easy-on-the-eyes, comfortable cozy effect like I want with regular lamp light bulbs.
