cainechow Posted April 19, 2014 Report Share Posted April 19, 2014 I just wanted to share my new LED setup for the 4 gallon pico reef tank. I was using two GU10 1x3w cool white + 2x3w actinic for a couple of years and wanted to try something different. I ordered a 10w Chip on Board LED module, thermal epoxied it to a little heat sink, drilled some holes for wires and siliconed a glass guard for the actual LED. I'm really liking the nice white look. We'll see how the coral and shrimp like the new light. It is much less spot lighty than the GU10 bulbs. This is the old LED New 10W unit And running on the tank And FTS. Apparently I need to do a water change :P I think I might see if I can run two units w/o the actinic on my planted 10G. Quote Link to comment Share on other sites More sharing options...
Deano85 Posted April 19, 2014 Report Share Posted April 19, 2014 Cool, how hot does the heat sink get ? Quote Link to comment Share on other sites More sharing options...
cainechow Posted April 19, 2014 Author Report Share Posted April 19, 2014 I'm not sure exactly, I don't have one of those laser thermometers. If it helps, I can hold the heat sink at the bottom on the sides and it isn't uncomfortably hot to the touch. It is quite warm but not scorching by any means.

Luke Posted February 8, 2017 Report Share Posted February 8, 2017 Hi. I am new to the sight. Not new to fish keeping. Always wanted to try the custom LED lighting. Could you throw up some more pictures of your wiring and lighting set up? Also wanted to see if you could link to where you got the the LED's. I will be setting up a small fresh wate planted tank in the next month or so. Was thinking of building a custom light hood. Thanks L Quote Link to comment Share on other sites More sharing options...
