If you did 96W on that tank, it would cook your corals. Go for a mix of 6500k and 460NM and dim to your liking. Theirs pure white in the 6500k not yellow like in filament lights.

Cook them? Ive been running the 96W T5 light for months now.

I figured they would like some more light actually...

Arent 6500k bulbs much more yellow? I favor the blueish bulbs actually. I am currently running 12000k bulbs with some 460nm bulbs. Still doesnt look white enough to me. Everything looks brown and rusty. More yellow...:-(

Okay, so from what I underatand, I could use 6500k and some 460nm blue to get what I am at right now. (12000k + 460nm T5 lamps). I favor the blue end of things. (White with some blue).

Looking around, these LEDs are $$$$ as heck! Im seeing prices in the $15 range for a luxeon mounted on a star and thats for the 3W led. How many would I need for acroporas in a 20g tank? Im guessing 60W would be a good area to shoot for. That would mean 10 6500k and 10 460nm? That would place me WELL over the maxspect price for a 60W setup! Seems rediculous to do such a thing with something out much cheaper. Anyone know how reliable those Maxspect setups are? Id hate to spend $200 and have it fail a year later.

Thanks!
Matt

So that kit is 24 x 3w Cree LED's? The PacSun 3w units have 54 x 3w Cree LEDs per unit. Again the price difference between DIY and ots is pretty small. Add your time and it becomes a labor of love.

Yea, and the Maxspect seems to be only offered outside the USA. Id have to spend $158 just to ship it to me! Thats over $300.00 for a low end LED system. I think this all was a great lesson to wait! Haha! Even DIY will cost me a good bit for the LEDs alone! My drivers cost me about $40 to make too. Id need one per strip of leds. Then I would need to buy heatsinks. After all that, Id feel left out since my drivers only power the LEDs rather than do anything fancy like color mixing. :-(

I think I will stick with T5s for some time.

Thanks!
Matt

Actually, i think you can get the maxspect for around 200 to your door. On manhattan reefers, the group buy is 190 shipped to your door.

Okay, it does appear there are some USA suppliers, but they require 20 day build time for the 60W. I am looking over the 60W details, (Im thinking the 60W is more than plenty for my 20g reef with SPS right?) and the 60W doesnt seem to be really worth it. It offers very little really, but still costs $160 and uses inferior LEDs. Really isnt much more than a snazzy enclosure with some LEDs inside. I could do that, but I have a bad habbit of using quality stuff and that drives the cost up. The 110W version is much better, but I cannot justify $400.00 on a system using cheap LEDs, and for a 20g tank. Too bad it has to more than double in price for only 50W more...They ought to leave out those large diode arrays. They cost more and as pointed out earlier, arent nearly as reliable.

Still seems that T5s are much more cost effective right now. Im sure in a few years, everyone will have LEDs.

Still keeping the DIY spirit alive, arent the CREE leds 6500k? Isnt that much too yellow? I have some acroporas, and like the blue colors. I am looking for crisp white with blue tones. I can tell you, I HATE yellows and pinks! Makes my tank look filthy! (Hate the URI T5 bulbs, all cast pink light!)

Also, at what point does lighting cook the tank? I am assuiming that putting on that 110W maxpect would cook a 20g?

Matt
