Well I ask this question because I hear it alot .which bulb gives best color or growth and in my opinion the metal halide has give me the best growth ..that being said the Ushio 10K has been my champion for growth ..Now for color the T5 bulb has given me alot of color from reds to blues even yellow's I use mostly ATI bulbs mixed with the Fiji KZ bulb.
L.E.D I have yet to try so cannot tell you if A brown coral will color up under them sure someone here can answer that question...either way what bulb would you say has given you the best growth and color.
