those drivers you have listed. is there a way to make them dimable? like adding a potentiometer to the LEDs or do you have to have a dimable driver that supports that?

Just received 9 more drivers and will work on the lights for the 90 gallon when I get some time. |

If you don't think that DIY saves you money, here is the Arduino controller built for you at about 10 times the cost of the parts http://saltydogaquariums.webs.com/32touchscreen.htm
He is saying that other touchscreen controllers will cost you over $1200, but here's a simple one at $72 - didn't really see if they had one at 120v http://www.aliexpress.com/store/prod...476755468.html Quote:

So is this driver dimmable with a 0 - 5 Vdc signal? From the ebay listing it doesn't really look like it. Or are you suggesting to put a 10K ohm pot from the output + to the return? I sure as hell hope not! Last edited by Seth81; 10-14-2012 at 06:46 AM. |

Doug, I'm curious as to how you're dimming the LEDs. I'm guessing the drivers have no dimming control correct? You're using the pot as a resistor? Any issues with over heating the pots?
