... Hi Marcelo. We have them over some new exhibit tanks (1500 to 8000 gallons). We originally had two LED fixtures (not sure of the number of LED s, but thereMessage 1 of 43 , Sep 14, 2010View Source

Personally, I would not use them on a planted tank unless the tank was very shallow. Otherwise, for general lighting, these fixtures seem to work well providing you have a good number of LED's.
Thanks Frank and Giancarlo! Right niw i have two 15 wat standatd florecent bulbs on my tank. They do ok, but i just don t think it s enough. I ll check outMessage 43 of 43 , Sep 17, 2010View SourceThanks Frank and Giancarlo! Right niw i have two 15 wat standatd florecent bulbs on my tank. They do ok, but i just don't think it's enough.

What is the reason for desiring LED fixtures? I have setup a couple planted tank and reefs with them and to be honest they are still in their infancy for our purpose, I've had to replace drivers, modules and even then the overall quality of the light is questionable... There are true full spectrum LEDs on the market, unfortunately very few products carry these, it's more common to see a mixture of monochromatic LED modules to acchieve the desired color, but spectrum suffers greatly as a result. No doubt this is where the future is going to be, just not quite there yet in my opinion, specially considering the current prices due to their novelty status. There are some very good units around but you will pay an arm and a leg for them and they will be surpassed in a year with cheaper solutions...
Right now the best buys are T5 fixtures. Two 54W T5 bulbs on a 55g work pretty well... use a fixture with adjustable legs in case you need to raise it to lower the intensity. Two 39W T5 bulbs can also work well for a less demanding setup...
What do you currently have on it?

However, I am unsure of the spectral quality of this light, and how well plants would do under it. To my eye, it looks white with no yellow or blue cast to it. Going by intensity, though, this fixture would allow you to keep just about any plants, IMO. How many LED's are in the fixture you are looking at?
