My DIY to my Red sea max 130 from Martin modular LEDs, the corals are doing ok though can't say any better than the stock PC lights....there's a lot of corals that I have in a small 34 gallon tank and maybe some chemical warfare going on inhibiting faster growth.
However, when the stock PC lights were in, it seem to illuminate the whole room more due to reflectors and the omni-directions of a tube PC light... A couple of corals such as a colt and kenya seemed to grow faster in the PC light but now it has slowed down... maybe the LEDs are a bit too bright for them. I leave the lights on at about 80% max. Everything else seemed to like the LEDs but no explosive growth.
Certainly one will save some money on electricity and bi-annual replacement of bulbs.
I think it will be a matter of time before T5 and MH will be a thing of the past ( in terms of saving electricity, bulbs ) but will this mean one won't upgrade to a better spectrumed , more computerized type of LED in the near future or will one stick with their current LEDS for a decade? Probably all the hard core reefers will indeed upgrade if the price is right.
