zoolan70 Posted January 4, 2015 Share Posted January 4, 2015 I'm building a 5x8 inch waterfall scrubber. Doing the math in my head, that means 40 sq inches per side, which requires 20 watts of LED per side. I'm not afraid of being a little underpowered, so I bought 16 of these: http://www.ledgroupbuy.com/deep-red-660nm/ They should use 2.3 W per LED at 700ma. I plan to drive them with this driver. It was the recommended one on LEDGroupBuy.com:: http://www.ledgroupbuy.com/inventronics-40w-driver-700ma-1/ wattage: 42W / max output voltage: 28-56v My ideal scenario would be to run each side of the scrubber in parallel, so I would have 2 strings of 8 LEDs in parallel, like this: Please disreguard the colors in that image, they will all be the Red LED above. Will this work? Thanks! Link to comment
jedimasterben Posted January 4, 2015 Share Posted January 4, 2015 Why would you run them in parallel? Link to comment
zoolan70 Posted January 4, 2015 Author Share Posted January 4, 2015 Because they will be in two different enclosures (one on each side of the screen). My thought was that each one would have + and - wire from their individual enclosure back to the driver. I can certainly run them in series, it just makes my wiring more complicated. Link to comment
jedimasterben Posted January 4, 2015 Share Posted January 4, 2015 I would run them in series. Wiring won't be any more complicated, you'll just have one wire connecting the two. Link to comment
zoolan70 Posted January 5, 2015 Author Share Posted January 5, 2015 OK, I'll do that. Another question...should I put in a fuse in the circuit, just in case? I don't think so, because the max output 700ma is still within the running range of the LEDs, but welcome any input. Link to comment
