Hey guys so I was wondering about broadening my LED light spectrum and I was considering adding some Violet, Red and Green LEDs from rapidled to my light rack. I have two questions though. One, would I be able to mount the LEDs straight onto the light rack since it's made of aluminum and have 3 big computer fans blowing over the tank. And second, if i have 4 of each color next to my PacSun fixture, would the intensity of the LEDs be strong enough to notice a difference in color along with the PacSuns? Here's a pic of the light rack and the fans that are over the tank. Thanks in advance, Fortunato
