I've actually never heard of a single 20W LED that does RGB mixing. I am more curious as to what it really is. That being said if there are such things as 20W LEDS then it would just seem that they would eventually replace conventional bulbs. This would be different than the Impression. Basically take a design spot and replace the bulb with a bright led - less power and no fans! I appreciate you letting me know as I just bought 4 design spot 250's and was going to be mad at myself for not waiting if this was on the horizon!
