Brlowe Posted January 20, 2015 Share Posted January 20, 2015 Hello all,I have purchased the RapidLED retrofit kit for my Biocube 29. I also purchased the Bluefish controller. I want to use the Bluefish Power Dimmer to run my LED's so here is my question.The power dimmer has a 40 DCV max input and each channel will drive up to 120 watts of LED's. What is the max voltage 14 Cree Royal Blue LED's need? and how many amps/watts of power will they be pulling? I'm trying to figure our what size power adapter I will need. Any help would be great. I do have a power supply and LDD drivers if needed but would like to use the bluefish dimmers.Brandon Link to comment
evilc66 Posted January 21, 2015 Share Posted January 21, 2015 What drivers came with the retro? Link to comment
farkwar Posted January 23, 2015 Share Posted January 23, 2015 I would figure 3v each and 3 watts each until you get them hooked up and running. Then add 20%. For overhead and efficiency losses. Until you get them hooked up to a volt meter and amp meter, you wont know exactly how much a string will pull. There is enough variance between individual LEDs to give you slightly different numbers, if you look at them individually. So I would start with 12 on the string. You can do 16 on an LDD if you give it 52-54v. I HIGHLY recommend using the HLG Meanwell as the power supply. Its safe, energy efficient, and waterproof. And its a driver as well. Link to comment
