Vance164 Posted February 26, 2017 Share Posted February 26, 2017 You would be lacking the blues you need if it's a planted freshwater light. Also I think the spectrums wouldn't be correct. And if it's not planted just for light to see fish it will not really grow coral. Quote Link to comment Share on other sites More sharing options...
xmas_one Posted February 26, 2017 Share Posted February 26, 2017 Depends on the fixture quite a bit. If this light was intense enough to grow plants, it will grow lower light corals for sure. Most planted FW led fixtures use white leds. White leds of any color temp have huge blue peaks in their spectrums. The corals won't look pretty, but they will grow. One of the best MH coral growout bulbs ever is the Iwaski 6500K, which also grows plants like crazy too. Quote Link to comment Share on other sites More sharing options...
