Chad September 18, 2011 Share September 18, 2011 As some of y'all may know, I have a background DIY LED project going... Like many others, I only purchased RB and CW. However, with all of the recent talk (and reasonable evidence) that this might not be the best idea (and I have always been a little worried about the color since I generally prefer a warmer color anyway). Anyway, I currently plan on a mix something like: RB - 33% B - 22% CW - 24% NW - 11% WW - 11% Anyone have something close to this that I could come and see?

Mando77 September 18, 2011 Share September 18, 2011 I have a DIY set up with 10 XP-E Cool White, 14 XP-E Royal Blue and 9 XR-E Regular Blue. You are more than welcome to come and take a look. Link to comment Share on other sites More sharing options...
OldReefer September 18, 2011 Share September 18, 2011 Chad, This site is Japanese, but the tool will really appeal to your inner engineer. It let's you model the spectrum of your finished fixture as you add and subtract different LEDs. http://www.1023world.net/diy/spectra/ I am adding high CRI warm white XPGs and some green. That dramatically smooths out the spectrum. CW, Blues, and RBs. All put their light in a vary tight peak. I thought Ecotech had gone crazy with their LED selection on the new fixture until I saw data. I bet nobody will be using CW 5 years from now. RB + WW gives a much more sensible curve. If you like a 20k look it is easy to add more RB. I am glad I was able to stir things up on RC. If you think the thread is disturbing, you should see the PMs I have been getting. Some big names have contacted me to validate the issue. Many many people have been having problems. Nobody wants to admit it. I guess if we are capable of going to war based on group-think, I guess this shouldn't be a shock. I love data, Bill Link to comment Share on other sites More sharing options...

BowieReefer84 September 18, 2011 Share September 18, 2011 You know I have them, but the trip is not close. 12 cw and 12 rb. Whites on a dimmer. I can go from yellow to windex. More than welcome to make the trek. Link to comment Share on other sites More sharing options...
BowieReefer84 September 18, 2011 Share September 18, 2011 Just placed an order for 4 blues, 4 warm whites, and 4 neutral whites. Want to play with things a bit here. Link to comment Share on other sites More sharing options...
Jim September 18, 2011 Share September 18, 2011 Bill, Any reason you picked warm whites over neutral whites? Jim Chad, This site is Japanese, but the tool will really appeal to your inner engineer.

OldReefer September 19, 2011 Share September 19, 2011 Take a look at the Cree spec sheet for XPGs. There is not much difference with cool vs neutral, but a big shift with warm. Warm white does not have that blue spike that duplicates the spike in RB and Blue. I think part of the problem is the way traditional LED combos all pound on the same peaks +- 20nm Link to comment Share on other sites More sharing options...
OldReefer September 19, 2011 Share September 19, 2011 The japanese site is a pain. Try going in at the home page and drill down through anything that looks like spectrum charts. It is worth the effort Link to comment Share on other sites More sharing options...
zygote2k September 19, 2011 Share September 19, 2011 I have a Robert Chu built DIY fixture. It has 18 blue and 18 white. Colors look fine to me. Come take a look see. Link to comment Share on other sites More sharing options...
Chad September 19, 2011 Author Share September 19, 2011 I have seen 50/50 CW/RB fixtures... that is what I based my planned split on... I am more curious about the addition of some of these other colors. Bill, I figured it out... the Japanese site doesn't work in Firefox for me, but it works in IE. Cool site, thanks!

Stu September 19, 2011 Share September 19, 2011 My DIY retrofit has 10 NW's, 17RB's, and 3 CB's. I started with 20 RB's and 10 NW's, but added the 3 CB's for extra pop for red/pink/orange corals. I've been very pleased with it. You're welcome to come take a look if you want. I spent a lot of time researching/tweaking plans, so I have some trial and error experience that might be helpful in planning your build. I think Bill is spot on about smoothing out the spectrum, and I have been thinking about replacing a few more LEDs with the colors he talks about. The peaks in RB and whites are very tight and unforgiving in my opinion. Link to comment Share on other sites More sharing options...
Guest thefishman65 September 19, 2011 Share September 19, 2011 I have CW and and RB in a 50/50 arrangement, but they are older XR-Es. You are welcome to come look. Old Reefer, just to be sure could you post a link to the RC thread you mentioned above? I am probably already following it. Thanks Link to comment Share on other sites More sharing options...
Chad September 19, 2011 Author Share September 19, 2011 Thanks, Stu. Will you be around evenings of this week? I can probably make it over on Wednesday. Rob, here is a link http://www.reefcentral.com/forums/showthread.php?t=2070551 Link to comment Share on other sites More sharing options...

Chad September 19, 2011 Author Share September 19, 2011 That works for me, although if another evening works better, I can do pretty much any night Wed-Fri or so. Thanks! Link to comment Share on other sites More sharing options...
