![]() i am also having a hard time getting past how much some of these sites are charging for a diy kit(most of them not even including the heatsink). wondering if i would be better off buying something like these and getting more light and paying less then a lot of the diy kits i have seen.
http://www.aliexpress.com/store/3178...with-Lens.html i also am wondering if there has been a standard set as to how many watts per foot you need. I have read quite a few threads and the number of leds used varies quite a bit and also have noticed that most people down even end up getting their fixtures up to 100% intensity once they are acclimated. so, do i really need 200-300 watts of leds over a 4foot 120 mixed reef with a bit of sps near the top??

![]() I'm about 90% done with my DIY fixture using 10 watt multi chip emitters. I've had it hanging over the tank for just over a month but need to take a more recent picture since I've stained the wooden frame I've made to hold the LED rails. Used a mahogany stain on the wood & am trying to figure out how to best attach gold coloured aluminum trim around the edges to hide the corner joints & screw holes. Also need to make some sort of cover to hide all the wiring on the top.
Here's my build thread, but like I said, photos are out of date as far as the wooden frame goes. It looks much nicer now with the stain applied & wiring cleaned up. http://www.canreef.com/vbulletin/showthread.php?t=82206 I'll try to get a new photo up tomorrow. Have the corner trim pieces on & one of the long trim pieces taped in place. Looks good.

![]() cant wait to see the pic mike... i really do like the idea of the multi chips from ebay as they are very economical and i liked the look of the light they put out when i saw you set it up at the frag swap.
is there a reason that you went with numerous rails of the 10w chips as opposed to just one rail of larger 25-50w emitters?

![]() Several reasons. Price, more flexibility as to colour blending, availability of the heatsink/fan combos for cooling, forward voltage of 9-12 volts (more common voltage for power supplies, possible solar power). For me the 10 watt emitters are a good compromise between the more commonly used 3 watt Cree, Bridgelux, Phillips, Osram etc and the larger multi chip LEDs. You don't need quite as many as when you're using the 3 watters, they put out plenty of light and cooling isn't as much of an issue as with the 20 and higher watt emitters.

![]() Mine is kind of a cross between fixture and canopy. Doesn't hang, it's supported by the wall behind and hinges up for full access.
