Isn't 185.6v x 1.05A 194.88w? Or did you mean 100w per board when run soft, like dimmed to 500ma? Are you sure it's not 92.6v total, both channels?
The diodes are being driven at lower mA about 160mA so the total wattage is lower. Each channel has 192 diodes, at 2.9v with 32 diodes in series equals 92.3v. There are six parallel strings of 200mA each totaling 1.2mA which with a 1050mA driver will drive the channel at 166mA per diode vice 200mA driven softer and similar5 for lower rated drivers. Each channel has 192 diodes with 32 diodes in series and six strings in parallel. Thanks for checking in. appreciate the insight.
I get you. I have been experimenting with this mix and I find it quite productive for all phases. I started this because I believe in group sourcing to reduce costs. If you can find enough for one board USPS priority is only $13 plus the $60. I know funds are tight as we all feel the new economy. i9 love this spectrum mixture and I figured others would too, plus sharing is so much more fun than selling, in my opinion. I have fun. But I have to say the hours spent building the pcb and circuits is very time consuming and tedious especially for these older eyes.
Yeah might as well be 2 commercial strips side by side.
This used to be a place of sharing now it is a place of criticism of others and nothing of your own to share just others objects to sell and make a commission. Sorry for your poor outlook on others efforts and freedom.
thanks. I studied a few other folks and their use of Samsung chips. The belief is to get the chip around 150-175mA of drive current by design, so matter what driver yiou use, the chip will deliver in the 190-200umol range, the peak for the diode to perform. I am already expectant of the outcome based on chilledledgrowlights boards, whcih I am currently running in place of COB's and enjoying the reduction of heat, power, etc, in a space twice as large as the COB's were in and everyone is happy. I want to provide a cheaper version of that. If you want all four channels buy from @Vitally, his is the best. I am looking for a good veg, clone and bloom light set. I have been experimenting with the strips at the same volt/amps and love the results, which is why I decided to make a pcb too. I figured if I anted to do it others would too. I am going to place the gerber file on my github account so folks can get it and modify it for their own use too.
Uh, it's a discussion forum. I think you were looking for eBay. Interesting that you perceive the posting of anything other than "hell yeah, I'll take 10" as offensive. Your little designing project did give some Chinese people some work though, so it wasn't entirely pointless.
