Paul_B Posted May 8, 2012 Share Posted May 8, 2012 I get them locally (1/2hr drive from home) for $3.50, cheaper if I buy 10 or more. Link to comment

Ok, I don't get it then. http://www.ledgroupbuy.com/cree-xt-e-royal-blue-1/ XT-E are $3.23 apiece. You're paying more for an older, crappier product. Link to comment

pwreef Posted May 9, 2012 Share Posted May 9, 2012 International Postage? You only got the cheapest place in the world to get the latest LEDs right on your little island. Cutter.com.au Besides it would be a shame to send the LEDs from Australia to Milad then back to Australia. LOL. Link to comment

Tinola Posted May 10, 2012 Share Posted May 10, 2012 Overkill for a 15x15x10? 12 RB XT-E (700ma) 6 NW XP-G (700 or 1100 ma?) 3 TV (500ma with 1 DIM4 Channel) 1 OCW (500ma with 1 DIM4 Channel) Using a DIM4 to control Link to comment

I hate cutter. Maybe if you live in Australia they'll actually answer your emails inside of 2 weeks and not screw you on every other order Link to comment
Justind823 Posted May 12, 2012 Share Posted May 12, 2012 So for my mini S I recently got a barebones 4"x8" jbj unibody to create a fixture of my own. I'm including the usual rb and nw combo but I'm trying to decide if i want to add a red or another color. I haven't seen anything but a b/w combo led light in person so I'm not sure if I'm going to hate the addition of a new color. What would you folks recommend adding? I'm just worried about getting a strange effect on a tank of this size. Link to comment

I'm just worried about getting a strange effect on a tank of this size. If you feel your reds/oranges arent really coming out, then you want to pickup a OCW If you feel your light greens arent glowing enough, then True Violets. If you want to have super colors all around, then both OCW and True Violets. FYI OCW is just a deep red, Turquoise and Cool Blue in one LED star. 1 Link to comment

Milad LEDGroupBuy.com Posted May 18, 2012 Author Share Posted May 18, 2012 Big thanks to Milad for all the help with this one. Nice! That looks like a ton of light. 12RB 6CW 6NW 4OCW Amazing colors. What coral is on the bottom right corner, orange one. FYI here is the OCW spectral graph: Link to comment
McJosh13 Posted May 18, 2012 Share Posted May 18, 2012 Milad, Has the true violet led changed or just the specs/labeling (i.e 395nm-430nm) I know it used to say 420nm. Also are you still planning on coming out with the HVTV? I'm in the market for some true violets and need around 410-420nm. Link to comment

Francois Posted May 18, 2012 Share Posted May 18, 2012 Hey Guys Can you please help. I want to build a led unit on a 47' heat sink for my build to be 59 x 31 x 23 lps and sps tank. A few questions: 1.) Must I rather split my sink in two or just put all leds on one big sink. 2.) How many leds would I need for my new build, 3.) What type of leds would I need for the best light setup, 4.) How to arrange the leds on the sink, bundle or spreaded. 5.) How many drivers, what type of drivers and how to setup them. I'm going to dimm the leds through my Reef Angel Controller. 6.) Must I go for optics for the leds or just put the led unit closer to the water/ Thanx you all Link to comment

Must I go for optics for the leds or just put the led unit closer to the water/ Thanx you all All this info can be found on this site if you go digging, but here is what I'd do. 1) You can make two sinks or one. Doesn't really matter. Honestly, for a tank that wide you might want to go with two full length heat sinks so that you can have better front to back coverage. 2) For a build that large 4 arrays of 30+ LEDs would be about minimum. 3) For the meat and potatoes of the fixture the easiest combo is 2:1 Neutral White: Royal Blue. Adding Cool Whites and cool blues to this ratio certainly can be done. If you want to make the build a bit more complicated 12-16 OCW would be about right for adding color to this type of set up (note standard cool blues are a component of OCWs). Adding 420 nm True violets can be done as well if you want. The number you add is up to you, but I'd recommend a number of true violets equal to the number of white LEDs you are using for your set up. 4) You're going to want to cluster your LEDs into arrays. Look around. You'll find array patterns similar to what you'll want. 5) Drivers depend on the number of LEDs you are running and how much control you want. Invetronics drivers are designed for LEDs, but they don't dim to 1% intensity. The standard 700 mA 40W invetronics driver can drive 6-15 3W crees. You could also go look at Steve's LEDs for drivers or buy meanwells. 6) For a tank that's 24" deep and keeping primarily SPS you'll probably want optics. Link to comment

We are trying another approach to it and hopefully this one will work. What wavelength are they at nominally now, or do they vary between that range? Too bad about the HVTV, any eta for info about the new approach? BTW.. hurry up and get those makersled heatsinks in, I'm looking forward to seeing some builds done with them Link to comment

BTW.. hurry up and get those makersled heatsinks in, I'm looking forward to seeing some builds done with them 390-430nm, peak at 405nm. They say that 420nm is "dominant", though. Did they clarify on what that meant, Milad? Link to comment
Guillz Posted May 18, 2012 Share Posted May 18, 2012 Nice! That looks like a ton of light. Thanks, yea it turned out to be A LOT! Blues are running at around 60% and whites 45% on the 700mA Inventronics drivers but the coral colors are great. Would definitely recomend a full spectrum set up. Link to comment

MakersLED is on schedule. Here are a couple of pics of the real deal. Extra long version being made... lol Link to comment
HecticDialectics Posted May 18, 2012 Share Posted May 18, 2012 Their dominant wavelength is 420 but they peak at 405 which I have yet to figure out what that actually means. According to various googled websites, dominant wavelength is the color it appears to the human eye. 405 is the highest actual wavelength. Link to comment
