I just read the spec sheet. It says inrush current max. I don't think it means the driver is drawing that kind of current but more like it can handle the current in case of like a power surge. Just guessing.

Well guys, my build is beginning....Just put in for 192 LEDs through Garage's GB. Only about $850 for the LEDs alone. Saved me about $400-$500.
Besides, most of us will not turn on 8 meanwells or 96 leds at full blast all at once. I hope it will not be an issue for my 120 leds build in an old house. (recently renovated)
I wish he included the xp-g white in the GB.
Swannking...getting XP-G's would have been nice, but the price was just too hard to resist on the XR-Es, especially with those $.22 optics he linked to...

Good optics should just snap on.....
DO NOT USE SUPER GLUE!
Loctite No Mess Adheasive ( the non toxic stuff from home deopt) worked for me.

Agreed, at the price points / discount, I cannot see how you could beat XR-E when it comes to bang for the buck.
I did order in extra in case anyone wants to get in on the stellar discount. Just shoot me a PM with the qty you want. They should all be in at the end of the week hopefully.
- $4.25 for royal blues / d3 bin
- $4.65 for cool white / we bin

westmoorenerd, Cannot wait to see your build! I thought I was rocking some leds at 72rb & 72cw over my new 225!!!
Optics Question
Optics Question
So I've been lurking this thread since the before the split and have an unanswered question regarding optics.
My theoretical build will have my LEDs <~6" from my tank top.
By my calculations: if I want even coverage without illuminating the glass I will need optics of 43.06 deg to cover 24" at a distance of 30" per LED.
I plan on using XP-G Crees and have come across very few option that fit these LEDs, or options that are a poor fit for the hobby.
What is the consensus on XP-G optics?

I don't know how nice my build is going to be...it's just going to be alot of LEDs. No way I'm going to be able to top some of these builds I've seen, especially some of the Arduino builds.

A lot will depend on how many LEDs and the amperage you run them at. I have 14 RB XPEs and 13 XPGs spaced 1.5" on centers on a 41 " length of 1x1/2x1/16" U channel. At 800 ma the back of the U Channel gets to 110 F very fast. With both sets of LEDS running at 800 ma the back of the U channel gets to 130 F.
I want to be able to run my LEDs at 1000 ma if I wish. I think it makes more sense to run the LEDs at the higher current then buying more LEDs and drivers. I think buy the time the decrease in PAR, the cost of replacements will be insignificant, especially if I can keep them cooler. I have a length of 1x1/2x1/8" U channel and some other aluminum extrusions I will try in hope of keeping the LEDs cooler.
Do you have 60 cool white and 60 RB? I am going to place an order with rapidled.

you guys should tread softly here. It was understanding that group buys must be confined to the local clubs only. We don't want this thread closed it is to important.

Anyone have info on the ELN-60-100 unit??? I see it on meanwells site but no data on it yet.
http://www.meanwellusa.com/LED.html
EDIT: Just spoke with meanwell, they did not know about the eln100 so it may be a product they will not release. However they did state they are coming out with a KLG or HLG?? "was hard to understand the guy" series rated at 100, 120, 150 & 185 all dimmable in p & d type with a possible 240 model to follow.

Question to LED DIY gurus:
I am currently running 75G SPS with plan to upgrade to 48X30(W)X20(H) rimless. After I attached a reefbrite LED strip (48 inch 24X 1.25W LEDs blue/white) to front my Aquanitics TX5 5-T5 fixture and see how nice the spectrum mixed tegether, I am convinced T5 + LED is my way to go. Now I am thinking to replace a T5 tube inside the fixture with a LED strip, I can drill a hole on fixture to let out power cord of LED strip. This way I can take advantage of nice reflector and active cooling of T5 fixture (and neat looking for example ATI fixture).
I wondering if such a product (LED strip to install in a T5 reflector) available, if not anyone would like to outsource my DIY work, I am not a DIY man but I think such a product will have a hugh market.
Thanks in advance!

"AC LED" is an oxymoron. They are inherently directional devices. If someone says they have an AC LED, it is almost certainly a plain old DC LED with some sort of rectification circuit built right into the same die. At best, they are inefficient.
Call ETG, they seem to have good selection and prices.
But, don't get hung up on calculations, and make sure you're interpreting the FWHM angle correctly if you DO want to try the math. Keep in mind that the very nature of the FWHM standard means that the number tells you very, very little about the actual spread of light, other than a general indication of "tightness."
Answered in the other thread you started.
