Has Anyone used LED Supplimental Actinics and Metal Halides?

Dan also built me a LED dimmer that is automatically starts from zero and goes up to 100% in 3.5 hrs, and at night after timer is "OFF" it goes from 100% to zero in 3.45 hrs pretty good feature.
So when MH lights are off at 9pm then blue LEDs start to dimm, it goes down gradually till like midnight and acts as moon light for awhile.
like it so far.
