Trick Posted February 7, 2012 Share Posted February 7, 2012 After reading Milad's observations that RB, Turquoise, and Deep Red make a bright white light when combined, I agree that I will need some more blue. The question is 2 or 4 more RB? If I went with 2 more RB for a total of 8 the end result would be: 4 Cool White 6500K 2 Neutral White 4500K 2 Deep Red 660nm 8 Royal Blue 455nm 2 Turquoise 495nm 4 True Violet 420nm I can always balance by dimming one array a bit but the reds and turquoise might make for some weird color balance issues if I have to dim one array too much. Try it and keep us updated. Link to comment

DaveFason Posted February 7, 2012 Share Posted February 7, 2012 Most board houses will make anything you want. The problem is you run into minimum orders, die fee's, material, ect. -D Link to comment
ignatz Posted February 7, 2012 Share Posted February 7, 2012 Does anyone know where to get custom 3or 4 up boards made like dave's? DorkbotPDX PCB Order might be a reasonable alternative. fwiw, etching your own board is fairly simple. Link to comment

blasterman Posted February 7, 2012 Share Posted February 7, 2012 I was looking at the cree LEDs and I dont see any CW warmer than 6500K. Cool White XP-G's that RapidLED is selling right now are certainly warmer than 6500k. I'd put them between 5000-5500k. I loaded up a bunch on my house plant light-bar, and the color difference -vs- cold white XP-Es is huge. Gorgeous color for a cool-white. Which is actually a good thing given we're getting such high efficiency numbers from realistic color temps, and warmish cool-white make for better a better base color. Link to comment
sliceOreef Posted February 7, 2012 Share Posted February 7, 2012 Your balance is about right, but why not put the whites and the exotic trio on one driver and the blues+violets on the other. Keep in mind that the trio mixes to a white which means you really don't need much of the white LEDs. I'd probably go with: Driver 1: 4 cool white: 2 neutral white, 2 deep red, 2 royal blues, 2 turquoise. Driver 2: 8 royal blues 4 True violets with an optional 2 Standard Blues The advantage here is that you can always have the deep red, royal blues, and turquoise LEDs in perfect balance. That's pretty smart. I didn't plan on using standard blue as I was under the impression the turquoise would be adequate. Do you think I would even notice the standard blues? Link to comment

Do you think I would even notice the standard blues? I'd say they couldn't hurt. Dave uses a ratio of 5 RB to 2 standard blue. 10 total royal blues, 2 Turquoise, and 2 standard blues would put you a similar ratio. Link to comment
ignatz Posted February 9, 2012 Share Posted February 9, 2012 How are we supposed to make an led board from an arduino? Oops, sorry the link title should have read 'DorkbotPDX PCB Order' but it led to the correct spot. It's a group buy on custom designed PCBs by square inch. You'll have to draw your own boards, source the components, and solder them yourself but that's pretty straight forward. There are other services like ExpressPCB or Pad2Pad that might be a better fit depending on the size of your boards and the level of assembly you want to pay for. Link to comment
androidx1 Posted February 12, 2012 Share Posted February 12, 2012 I've had this ratio for months but using my single LED's. The 13up is only better with the LED's being much closer. The photo's above are the exact same ratio minus one deep red. Here are tanks with the exact same ratio as the 13Up. -Dave Hi Dave, Wow those photographs are beautiful!!!! So Im in the middle of a build, and Im about to finally purchase my LED's and I keep holding off because im unsure which whites to buy. It seems that there is a large variation in color temp withing the "cool whites" or "neutral whites" for that matter. To take the guess work out for me, i was wondering if you can provide me with the specific "Cool whites and neutral whites you are using? I remember reading that you said the cree whites are not efficient and you recommneded using something other than cree. Can you provide the manufacturer and part number of the whites you are using? If you are not comfortable posting them on here, you can shoot me an email if you dont mind. Thanks, Mike Link to comment
NavyChief52 Posted February 12, 2012 Share Posted February 12, 2012 In all its glory! CW,NW,DR are in a series. I found this to be the best way to run them without a million drivers. The Blue, Royal blues are also in series together. This combo looks incredible and is by far the easiest thing to wire. The modules can also be ran in a parallel with each other for monster builds. Using a Burquest Gap Pad instead of messy thermal grease/epoxy or thermal tape. This stuff is extremely easy to use and also can be pulled off easily if needed. The overall size is 2.9"x1.5". Enjoy! -Dave Sent you a message on your site. Curious of the amount of work it would take to remove the Edison Opto 6 x 3W modules (4 total, 2 blue and 2 white) and replace them with 2 of these. The Nanotuners 4.6 Kit shipped with a large heat sink and their Duo 700 dual channel controller. Would prefer to keep everything and just remove the Edison Opto modules if the Duo 700 dual channel controller can drive these. Thanks Link to comment

If you put the blues on one channel and the whites on the other, you'll have 12 on one driver and 14 on the other. Link to comment
DaveFason Posted February 12, 2012 Share Posted February 12, 2012 Mike - Because I am a nice guy.... CW - 5000-5300 NW - 4000-4300 I prefer the Rebel ES line. I also have these in stock. Navy - It will be extremely easy. Drill twelve new holes, install modules, re-wire and tada! -Dave 1 Link to comment

Trick Posted February 12, 2012 Share Posted February 12, 2012 Milad had some really nice 5000k cree XM-L's on his site for a while, but they are gone now, atleast i think the new ones are different. I used those by themselves and it worked really well, not too purple like most nw/rb builds, but next time I would add one or two Cool whites. Link to comment

IIRC...... Those pics are from Rehypes' tank thread. At the time he was using one of Daves' Nano-Box fixtures. As far as I know I don't think there was any photo touching done. Link to comment

blasterman Posted February 13, 2012 Share Posted February 13, 2012 They are still kicking around: http://www.ledgroupbuy.com/cree-xm-l-white/ XTE 4500K and 6000K are Incoming, not as good as the XML but similar to the XPG How are they not "as good" as the XML? The XTE is more efficient and they cost like 1/3 the price. The XML has to be driven pretty hard to get a price benefit out of it although it's a better deal in neutral -vs- cold white. The photo's are as true as they can be! Keeping it real like I always do: I've listen to Trick about a million times call NW based tanks too purple and I've tried to defend the combo to the point I've given up replying - don't turn your %^&*ing royals up so screaming high and it's not a problem. Now we have pictures that in my opinion are poster children for exactly what Trick is complaining about. The only way to get zoa skirts to glow like those in the pictures is to have RB cranked up to absurd levels, and you know that Dave. The color has nothing to do with 660nm or any other LED color. RB has been jacked up to get radioactive colors, and whites have been dialed up to compensate. When online coral sellers do this with softies is drives most of us nuts because we know the colors are fake. Link to comment
Trick Posted February 13, 2012 Share Posted February 13, 2012 Ya know those NW/RB tanks............... there just soooooo purple....................... Just messin with ya blasterman. Link to comment
DaveFason Posted February 13, 2012 Share Posted February 13, 2012 Blaster - Agreed. That is the joys with LED's, make it how you like it. The 660 has nothing to do with those colors but the RB and blue do. -Dave Link to comment
