LED Floodlights?

[Jim96SC2]

Anyone tried using them for a tank? Costco was selling them, claims 30,000 hrs of use and they only use 5w of energy. I thought of matching these to a dual actinic T-5. Question of coverage was an idea.

They were like $14 per, and I figured even if you needed 4 of them for my 58g it still would be a good deal in both initial costs and in upkeep costs.

No ideas, I may have to be the one to trial this..

20w of anything is not enough to grow corals. So no, I do not think it would work.

I tried these out a month or so ago... Cannot comment on long term success (got busy with my new setup and had to take this down), but for the three weeks or so that I had the light over the tank, the Zoas I had in there were happy..

Here is a thread I started that has a couple of pics to give you an idea of what it looked like

20 watt of compact flourescent will grow kenya trees, since LED is more effecient i imagine something might grow under them, but since LEDs also sometimes output specific wavelengths it might not output the ones you need.
