need some help on a 100 watt led build befor i buy them

[rocking]

tank size is 24" by 24" by 84" = 210 g

what i am doing is a led build useing 100 watt leds dimable with 50 watt supper altenick
am posting the specks on the cool whit led part and specks on the driver
the test on 100 watt led with a par meatter was at 420 at 24"

10= 50 watt each
5= 100 watt each

whats there a question in there?
seems like an excessive amount of LED's for sure..
4 x 50W (200W)is plenty on my 120G 72" tank..

You plan to have 1000W.. I bet you will be able to see if from space.

I have 2 100W led above my 150gal on 2 separate 10x12 heat sinks each one has the 100w led in the center and 12 3w actinic LEDs around it I had to dim the 100 probably close to half and turn the blues down about a 1/4 was very brite. Before putting all that light and money above your tank maybe just buy one set and hook it up and put it over your tank see what it looks like. when I was making my first set up I was told to think of the 100w led as if I was using a 250w halide I had 3 100s wish I would of used 50's instead but thats what dimmers are for right.

can you provide a link to the led page?

Before you waste $1200, do yourself a favor and study at least this thread:
http://www.reefcentral.com/forums/showthread.php?t=2128756
Then buy one chip, one driver and one heatsink (what this Chineese seller is trying to sell you is inadequate, you need CPU-type heatsink).
This way you spend only $150 and get to see it over your tank.
Also if you have an established tank, I would be real careful with LEDs. You may loose your corals to either too much light or wrong spectrum. Good luck!

rott, you may be better off anyway. running the 100w leds at 50% is much safer (for the led) than running 50w leds at 100%

Multi chip setups work very well as the thread linked above can attest to.

a totally different route to consider though, just to have done your homework is the single emmiter (3w-5w star chip type) builds. using the latest CREE or Luxeon Chips and optics you'd probalby need between 100-150 of them. Less if not keeping SPS. Many successful builds on the forums using this approach for 200+ gallon tanks (gives you more controll over end color IMHO, but much more soldering ) Lots of US based DIY sources cater to this approach. not nessesarily the cheapest upfront cost but can offer savings in power use over the life of the fixture. just something to consider.

driver wise:
I'd strongly recommend looking to meanwell or inventronics for drivers. Meanwell is very cost competative compared to the crap out there on Ebay(you never know what you'll get though, the couple 700mA drivers I ordered before knowing better only ouput ~500mA and are kind of scary looking compared to a meanwell). Powergate LLC. is a great place to browse driver selections.

What can you grow in your 150 (48"x24"x30"?) with that? What chips did you use and how's your color rendition?

I am considering some of these 60w 10K/RB hybrid chips over a 120g (4'x2'x2'). Either 2 at/near full or 4 dimmed, possibly with some UV supps.

What do you think of this idea? I'd been looking at the 100w chips on the other thread that need dedicated CPU/GPU heat sinks that don't have space for adjacent LED placement (I abhor disco effect). With a good fan-cooled sink, do you think I could place some 10w or 20w LEDs directly adjacent to the 60w?

my 150 is 72x18x28 I use it mostly for FOWLR it does have a few soft coral's in it mostly houses a few angels and some tangs. The color is slightly blue that matches my 14K halide in my other tank. I bought the 100w leds online I followed a link from a different post several months back and the 3w actinic all came from rapied led with mean well drivers that are dimmable was my first go at leds.
