Just as a follow on, I'm not trying to poop on the product or anything of that nature. I just feel that with LED technology being fairly new to our hobby there is alot of misinformation, misunderstanding and marketing hype such that people don't really know exactly what they are getting and what the particular LED fixture they are buying is capable of doing. The manfacturers don't help in this as they don't release important specifications on their products and they don't publish PAR numbers (which they must have tested).

So what happens is a customer buys an LED unit to replace MH or T5HO or whatever and then it doesn't have the results or performance they believed it would so they conclude LEDs are no good and get on the interwebs and talk about how bad LEDs are and how their corals stopped growing or lost colour etc.

I believe LEDs are the future of reef aquarium lighting and can replace T5HO and MH in most applications if implemented appropriately. That means high quality LEDs driven at 3W with secondary optics if you need very high PAR or want to have penetration in deeper tanks. Bare LEDs without secondary optics for lower light requirements or shallower tanks etc.

I believe Reef Brite's literature says these can replace T5 and VHO lighting which probably means (if you read between the lines) that these will not perform as well as MH or T5HO. So they will be great for some applications but not for very high light requirements or penetration into deeper tanks.
