Mr Liriel made one and uses it over one of his tanks. The new technology does work with SPS corals.

it seems like a cheaper route and more lifetime stability since LEDS last a long time. i havent decided weather to do this or MH. being military i dont have big budget. you know how that works murf lol E4=broke lol

man i just looked @ the par38 bulbs for 12,000k is like 110bux. man i would probably need like 4-6 bulbs with 6 LED's in each to work on my tank so i might stay with MH idea for now

Well if the Photon Canon come out next week as promised, and the numbers are there I will be replacing my MH ;-)

How do you know how many of these dudes to get for your tank?

I plan on going with 3 for my 8' tank. I might have some dark areas but it won't be where I have corals.

Id think they would be similar to MH with one every two feet as the recomendation!

I've been out to their site and I don't see a chart that would help with that decision. I'd think that the 2 ft. per lamp would be sufficient, so 2 lamps for a 4 ft long 120.

I did the math and if you run your halides 8 hours a day, it is just over 17 years to get to 50,000 hours of use. So that means that you'd go through 34 MH lamps compared to 1 LED lamp. If you use 2 MH lamps, like I do, that would be 68 MH lamps. So just uing 1 lamp for price comparison, at $75/lamp, you'd spend $2,550 on 34 lamps over 17 years. So, $549 vs. $2,550.
That's an easy call!
