ajmckay Posted February 18, 2009 Share Posted February 18, 2009 (edited) He11 yeah! New LED Guide!!... Bookmarked... One thing that I'm really glad you stressed in your article is the potential energy savings of LED lighting. For a smaller system it won't be a whole lot per month, but it really adds up. Combine that with the fact that you don't have to replace bulbs every year and you've got a real cost savings. I did a simple calculation Saturday a $2000 LED setup vs. an $800 800W metal halide. The LED array would break even with the increased up-front cost in only 3 years! Now in addition to the efficiency, could you post some links to how well LED's work for coral growth? I've googled some stuff, but I haven't found very much recent information (from well trusted sources giving accurate numbers) yet similar to all the stuff you can find for MH or T5. I'm not just talking PAR, but rate of coral growth, algae growth, etc... Keep up the good work. I'm also looking forward to the completion of your latest LED array....

Coral growth is going to be a difficult one to quantify. I can tell you based on my experiences what it could be, but I don't have the tim eor the funds to set up comparitve systems to see how well a coral would grow under different lighting systems. I wish I could though Adin, thanks for the sticky, but I wonder if this wouldn't be better kept in the lighting forum? Quote Link to comment
Marteen Posted February 18, 2009 Share Posted February 18, 2009 I agree with the sticky but I think it would serve it's purpose better in the lighting forum. Quote Link to comment
musthaveitall Posted February 18, 2009 Share Posted February 18, 2009 Yay!! I have been waiting for something like this!! I cant wait for the rest!!!!!!! how long?? THANK YOU! Clint Quote Link to comment

The Propagator Posted February 18, 2009 Share Posted February 18, 2009 Yeah you would think this would have been a sticky in the lighting forum since it is all about LED LIGHTING LOL ! Quote Link to comment
evilc66 Posted February 18, 2009 Author Share Posted February 18, 2009 I reported to the mods. Now we wait to see their judgement. Quote Link to comment

er1c_the_reefer Posted February 18, 2009 Share Posted February 18, 2009 where would one go about buying the LEDs and componenets? recommended dealers? Quote Link to comment
wobbabobba Posted February 18, 2009 Share Posted February 18, 2009 Think you could list of couple of DIY LED threads that you think are built well? Maybe some different set-ups with different brands, optics, heatsinks and all that good stuff so everything is in one place. Quote Link to comment
evilc66 Posted February 18, 2009 Author Share Posted February 18, 2009 Thats going to be covered in the next section in detail, but here are a few to get you started: LED Supply Luxeon Star LED-Tech (For our European bretheren) Deal Extreme Kai Domain This will give you an idea as to what you are looking at part wise. There are many other places to get supplies. Some better than others depending on quantity and quality. Think you could list of couple of DIY LED threads that you think are built well? Maybe some different set-ups with different brands, optics, heatsinks and all that good stuff so everything is in one place. I'm sure I can do that, once I get permission from the relevant people. 1 Quote Link to comment
Ryan110484 Posted February 18, 2009 Share Posted February 18, 2009 For those of you who have a par meter....... What would you say the average par number is for a single LED with 40 degree optics at 12, 18 and 24 inches. If you don't know thats cool, but for a guestimation... what would you say?

evilc66 Posted February 18, 2009 Author Share Posted February 18, 2009 Don't have numbers for a single LED, but I do for an array. Array of 10 LEDs. 4 XR-E Q5s @ 1000mA, 4 XR-E royal blues @700mA, 1 3W UV @ 700mA. 12" - ~500PAR 24" - ~200PAR These numbers can vary based on brand of LED and lens, and the drive current used.

evilc66 Posted February 19, 2009 Author Share Posted February 19, 2009 Thanks everyone. Kamy is being kind enough to take my guide and tidy it up a little and format it so there will be a downloadable pdf that you can print as a handy desk reference, once it's done of course Quote Link to comment
