important to know the pur, kelvin temperature,
Interesting to see an old post about light. This hobby has to do a lot with biology & in this case optics. It's important to know the PUR, Kelvin temperature, & to a lesser extent lumens requirements of corals. It's these principals by which light should be selected. This goes very well into detail about light but, one thing that is important to point out is that the LEDs usefulness in a reef aquarium is measured by the kind of LED diodes it has since the 3w diodes are the only ones that'll produce a broad & powerful enough spectrum... Most importantly in the 400's nm (blue) as many would know. Sad to see how many companies have succeeded in selling LEDs marketed for reef aquariums yet can only support soft corals.
