biodives Posted May 12, 2017 Author Report Share Posted May 12, 2017 I made two 4-footers to act as second lights over two 24" deep (front to back) tanks which is too wide for a single light to cover unless you raise it up. Cost for each light about $35. Each can generate up to 4400 lumens. One participant build a light for a 5' tank using a single 4' module, also rated at 4400 lumens. The host showed 2' lights he had built in a much smaller package so it would fit in a narrow space between tank and shelf. Another light was built using 3 daisy-chained modules including one double-intensity module, but I didn't see the final product. A neat trick was to use rain gutter as the light housing for which you can buy water-tight end-pieces that will be more durable than my tape solution. Some others were going to assemble their lights at home. Quote Link to comment Share on other sites More sharing options...
Iceturf Posted November 17, 2017 Report Share Posted November 17, 2017 Can you send me some spec's on these? Are they from Digikey or ?? Quote Link to comment Share on other sites More sharing options...
biodives Posted November 17, 2017 Author Report Share Posted November 17, 2017 I just build a bunch more for my new tank racks. Instead of individual lights per tank there is now one 6 foot light per 2x6' shelf, 7 lights in total. After about 10 months there has not been a single failure in power supply or LED module and I have had sword plants, water hyacinth and frogbit form flowers under these lights.

jvision Posted November 17, 2017 Report Share Posted November 17, 2017 I tried to order enough for just 1 or 2 lights, but the minimum on the parts I wanted was 25. I'm selling for T5HO for now Quote Link to comment Share on other sites More sharing options...
biodives Posted November 18, 2017 Author Report Share Posted November 18, 2017 At futureelectronics.com some have to be bought in bulk but others can be bought a piece or in pairs. Those are the ones I've been using. It's a bit frustrating that there doesn't seem to be neither rhyme nor reason to why some can and others can't be bought a piece.

biodives Posted November 18, 2017 Author Report Share Posted November 18, 2017 Actually I have one unused 2 foot LED strip (CRI 90, 4000K) and a 4 foot light with two 2-foot modules (I assume my standard CRI 80 5000K) and power supply left after my tank rack renovation and that I could sell. PM me for details if interested. Quote Link to comment Share on other sites More sharing options...
