I've been searching and reading and just recently came across T5 fluorescent light. they have 80 watt lights that produce 7000 lumens and are in the red spectrum 3000K and in the blue spectrum 6500K.

Been doing a lot of research lately, i had seen something about one of the two lamps being able to power both bulbs but needed a modification. Something to do with the starter i believe.
