Aquarium Dude Posted December 13, 2006 Report Share Posted December 13, 2006 Just wondering what brightness of leds people have used (eg 3000 mcd) and for what size tank and how many. Quote Link to comment Share on other sites More sharing options...
hazymranch Posted December 18, 2006 Report Share Posted December 18, 2006 I have used 5000mcd x 4 on a 700mm tank and it looks pretty good. I also have 2x 5000mcd on a 2ft tank (more shallow) and it is a bit better. I also have 3x5000mcd + 2x3000mcd on a 4ft tank and it is a bit scarce (deeper tank). My preference is for the 5000 mcd lights. Get the largest spread you can to avoid spotting. For the price at Dick Smith's (around $4 each), a viable alternative would be here: http://www.lc-led.com/View/itemNumber/64 They seemed like good bulbs (30 degree spead as opposed to the 18 degrees for the DS bulbs) and the price is good even with shipping and the exchange rate. A good site I found was http://www.kaotica.com/frag/diy/moonlight/ Good luck Quote Link to comment Share on other sites More sharing options...
Ira Posted December 18, 2006 Report Share Posted December 18, 2006 www.dpt.co.nz is also a good place to get them. That's where I've bought my leds before. Quote Link to comment Share on other sites More sharing options...
Aquarium Dude Posted December 18, 2006 Author Report Share Posted December 18, 2006 How do you reckon green would look (525nm)... It might look interesting... Quote Link to comment Share on other sites More sharing options...
Ira Posted December 18, 2006 Report Share Posted December 18, 2006 I reckon it would look like you've got a massive algae bloom. Quote Link to comment Share on other sites More sharing options...
