no its not it goes by kelvin you want a metal halide that puts out 5000 ke;vin to 6500 kelvin thats for growth if you want your plants to flower them you use 2700 kelvin .thats the red side of the spectrum the higher the number of kelvin is white to blue color. and if you have a reef tank you have to have 5000 kelvin or higher or your stuff will DIEtylerperkins;2648307; said:

actually a very common bit of misinformation, corals will not die if kept under lower kelvin lights, they just will look brown, however they often grow very quickly because fo the higher par. most issues people have with corals dying after they switch to lower kelvin lights is the corals are stressed out because they suddenly get overwhelmed by a very high par light.the red side of the spectrum the higher the number of kelvin is white to blue color. and if you have a reef tank you have to have 5000 kelvin or higher or your stuff will DIE
