So I'm looking to replace my PC
lights over my 55 (4 65W square pin). I want more of a blue look to my tank as you get with LED
's and metal halides and such. I found a 14k PC
bulb but it appears to be 75% actinic and 25% daylight. thus making 14k color. Will this be enough white in my tank for the corals to grow? Im assuming going this route i'd have to replace all four with this same bulb right? or can i do two 14k and two 460nm? i like the royal blue better than 420. heres the link to the bulbs.
OH and there PC
UVL Power Compact bulbs
and heres another i found
