I am adding a new light to my twelve gallon eclipse as my plants seem to be struggling. Anyway its a 11" long and 4 inche wide, "narrower the better" for my fitting needs(aka filter taking up hood space). It comes with a 50/50 bulb which im going to discard but the only replacemnet bulb on there website is a 12,000k bulb. Is this still ok to use...or better then the 6700k bulb? the bulb is a 18 watt straight pin. I found a 18w 6700 k
square pin(fostersandsmith) but no straight pins. If 12000k is good i'll go along with that otherwise i'll continue to search for more options, will i see a improvement in plants and fish with this additional lighting or is it not worth the money?......Thanks in advance i love this site!
