Burningbaal Posted June 26, 2012 Share Posted June 26, 2012 ok, putting together my led setup for the femto tank. so here's what I have: "moonlight" driver, puts out 350mA (constant) at 0-13v 2x: 'moonlights' 3.3v at 350mA 1x: violet 3.5v @ 700mA, (3v min, 4.3v max) 1x: cool white: 2.81v @ 350mA the driver on the website says any 4 diodes (not just the moonlights), so I bought the white and violet. can I just put them in series?

Burningbaal Posted June 26, 2012 Author Share Posted June 26, 2012 35 views and no replies...here's my idea (not attached image) I can wire them up in series and add a resistor (theoretically 11.423 ohm if I did the math right) for constant current of 350mA at 13DCV. but of course...I want more out of it. so I was thinking that it would be awesome to be able to just run the blues at night and how can I rig up a circuit with a switch (timed would be best, but manual switch will suffice...for now) to do that. it seems that if I branch it so there's a resistor (R1) equal to the CW+UV resistance, I could make R1and the CW+UV diodes be switched. so the RB are always on and the CW+UV get switched on and off, but without throwing off the RB voltage/current (because R1 takes that load?). Also, I'm still not sure if the unswitched resistor (R2) is needed since the driver says "0-13V" and "constant current 350mA"... am I crazy?

Googs Posted June 26, 2012 Share Posted June 26, 2012 Yes, you can put up to 4 diodes in series with one Moonlight driver. I just installed two moonlights in my canopy with no trouble. I did wire up all four (bought the 4 led kit, only needed 2) Quote Link to comment Share on other sites More sharing options...
Jeramy Posted June 26, 2012 Share Posted June 26, 2012 Although it sounds like you have this worked out. I would contact them and see what they recomend as a solution. The might have a really simple solution for this, or at least could give you a more definative rsponse to your question. Quote Link to comment Share on other sites More sharing options...
Burningbaal Posted June 26, 2012 Author Share Posted June 26, 2012 @googs: my main concern is that I'm not just using the 'moonlight' diodes...the site says '2-4 of any diode', but I'm surprised cause the moonlight ones are supposedly for a really different current than the violet, and especially than the CW...

NoobtoSalt Posted June 26, 2012 Share Posted June 26, 2012 I would ask them on rc. Everytime I messaged them they get back to you fairly fast. Best thing is to just call them. They were suggesting I don't use the moonlight driver for my edge, but your much smaller then that so it should be fine. Good luck.

Burningbaal Posted June 26, 2012 Author Share Posted June 26, 2012 good call...email sent. I think the "R2" resistor in my sketch is unecessary, but if I do the switch, R1 will be important so the blues don't get crazy bright all the sudden.

Burningbaal Posted June 29, 2012 Author Share Posted June 29, 2012 they said the switch idea is untested and therefore unknown. they said if I was trying to do it with a regular meanwell driver it would surely fry the diodes that are before the switch (because of the brief moment that the circuit is open between the CW/UV and the other side), the inrush of power would surge the blues. he said it may be fine with the moonlight driver (so low-powered), but they've never tested it. he told me what I would need to test it (or, he said, just try it and I might have to buy new LEDs if they popped). all that to say, I'm just going to wire the 4 in series, they'll all drive at 350mA (perfect for the blues, 1/2 for UV and 1/4 for the white of 'full power'). so I'm hoping that gives a really high-K spectrum and still sufficient light. if things are suffering, I could buy a second driver to power the white/UV separate from the blues, which then could be used on a separate timer. so that's what I know.
