The DIY will be cheaper, but I think 3 of the 15 inch RB would probably be all rights. I did not see who made the LEDs so it is hard to tell about efficiency, but I expect the DIY will also use less electricity.

the DYI kit has 10 RB Cree XP-E and 10 cool white Cree XP-G led's.

Yes, and three 18 inch have 18 LED. What are you trying to ask?

you said you did not see who made the LED's for the DYI kit, also I am looking at the 15" Reef Brights so it actually has 12 led's not 18 in each strip. The DYI has 20 3w Cree led's, the reef bright xho's have 12 led's and I would get 2 strips totaling 24 leds....hope this explained it, if not then I misunderstood what you were getting at

The 15 inch version only has 6 LEDs (I don't know who makes THESE LEDs) according to the web site I saw. So I did three sets (3 x 8 = 18) to get close to the DIY number.

There's some 60W Cree units being made out of China lately. Looks like this person is importing them http://www.amazon.com/SWC-CREE-DIMMABLE-LIGHT-AQUARIUM/dp/B004KJKDJU
Here's another configuration and better pricing
http://www.ocreef.com/ocreef_60_watt_cree_silo_high_power_aquarium_led_light_fixture
can get them direct from here but don't know about shipping cost
http://www.alibaba.com/product-gs/477318671/Hight_quality_60W_CREE_LED_Aquarium.html
Seem to me they are all made in same place...same connections, same dimming box, same LED count, same words, etc...actually they look real nice going by the pictures. Personally i would contact the alibaba link and get shipped cost to US. This is where they are coming from anyhow.

have you or anyone else used that site before "Alibaba.com"??????? Not so sure how trust worthy that really is
I order a fair amount from it(not lights, but other Tech. related stuff) Kind of like our version of Amazon... - You have to be careful, have gotten burned before and had items held at customs for months due to patent issues. However, I continue to order.

I've used Alibaba. Never had an issue. Seems like just a place for all the China companies to sell their wares. You can find incredible stuff there to be honest. You name it and you can find it there.

Excellent...keep us posted.
Did you happen to ask what current they are driving them at?

No I didn't, I was just browsing on ebay and happen to see those guys list a few on ebay for a little cheaper than they post at the site and cheaper than the same ones but with a different name on amazon so I pull the trigger. Just in case that is not enough for my mix reef 72 I got in contact with another person on ebay that made his own LEDs and brought it from him locally.

I could use some advice on an led fixture for my frag tank i'm installing inline with my display. Its an 18x18x16, and i'm looking for the best value to light it. I can put SPS at the top of the tank no problem. Is there something that is going to be a better cost/value than 2 par38 bulbs? I'm looking at about $200 shipped for 2 of those, but i've also been looking at these 120w fixtures from china on ebay.

for about $170 shipped which use 3w leds, have fans and look great. I realize its china and you get what you pay for but i'm looking to keep cost down and even if one led goes out and that scraps the whole sheet you still have a nice enclosure w/fans for DIY.
My other option is an led fixture sold by a local lfs which looks just like the evolution and reefkoi fixtures, but i'm looking at about $300 for those.

I might be buying a 210, and am still thinking LEDs. I want to make 3 pendants (one over each section), and use 16 XM-L's on each powered by a ELN-60-48-D. I also want to run 60 XP-E's in parallel off an HLG-185-48B. I am still unsure what degree of optics I want to use considering the tank is 30" tall. Any suggestions? Would this be enough light to grow SPS at the bottom of the tank? I also plan on dimming it all with an Apex. Any advice and direction would be much appreciated. Thanks!

If you place 16 XM-Ls and 60 XPE over each section I don't think you will need optics and I would expect SPS on the bottom.
I believe it was DWZM that measures in metric crap tons, but that sounds like a metric crap ton of light.

That was why I thought 60 blues which is almost 4:1 which I think is about the right mix for XM-Ls. Of course it depends on the current of the XM-Ls.

They should be ok at 1 amp if you have good heat sinking.
ah, ok. I also have another question. I have a friend who owns a fish store. He has 63 30g long tanks (48WX12DX12H). Theyre lit right now by a single T5 bulb. He wants to eventually replace these with LEDs. The lights are about 12"-18" off the water. He isn't trying to grow corals, he just wants to light them. What is the most cost effective way to light them sufficiently? He has thought about stunner strips, but I'm not sure if that will be enough light for the tanks suspended at that height. I was thinking of a constant current driver, and one long heatsink with no fans. Any recommendations?
