The LED's on the reef units are different spectrum of course than the hydro lights.
We need to nudge in a certain Jimsflies with his PAR meter so we can get the official numbers, but we're expecting it to be somewhere between 3 T5 HO bulbs and a 150w HQI. Each light has about a 24" spread, and the fixtures themselves are 12"x12"x2".
You can plug them in end to end, up to 28 units! - so all that's plugged into the wall is a single power cord.
They're 100% on or 100% off, but come in at an economical price of $150 each when you buy 3, $165 each when buying 2 and $180 each when buying 1.
We're pretty happy with them especially for the pricepoint. I'll see if I can get some pictures of them and the tank they are running on soon.
