The Evergrow seems like good light, again the price is inviting and 3 channels over 48 time periods as far as I understand is great. What I don't know is what brand of LED they use. I know Razors have CREEs. The fact that they're bulky doesn't bother me as I look at the tank not at the light . The fans, everyone with bit of electronics knowledge could change themselves if not bothered about waranty.
