Nf, a question for you about your light setup, if I may: Are you running these 4000k strips for flowering or just veg? If flowering, are you planning to supplement some red?
I can be named a horse and you can flog me if you wantnot to flog a dead horse here nfhiggs, but links may be helpful.
I've got them over a flowering plant right now, replacing a Galaxy Hydro light.. She is about 5 weeks in I think. Nothing else on her.Nf, a question for you about your light setup, if I may: Are you running these 4000k strips for flowering or just veg? If flowering, are you planning to supplement some red?
Yeah, when I first turned them on after putting them in the cabinet, they were at 1.4 amps and they hot a little hotter than I like, so I turned them down to 1 amp,.My Samsung Influx strips run great on HeatsinkUSA 1" profile at 1.4A, but I prefer to run them at 1A on cheap aluminium angles.
Yep 1A seems to be the sweet spot for these strips.Yeah, when I first turned them on after putting them in the cabinet, they were at 1.4 amps and they hot a little hotter than I like, so I turned them down to 1 amp,.
Yeah, I wish. A cheap light meter is on my "to buy" list.... (wish I could afford a PAR meter or spectrometer)Have you a light meter of some sort? par, lumen, lux (maybe your phone) just curious, love this build.
BTW, I found out all but one of the voltage/current displays I have are WAAAAY off (like double the actual amperage). They are actually running at a little over 500 mA each, according to my multimeter. I'm gonna have to go back and find the seller I got the first display from, cuz its dead on...Yeah, when I first turned them on after putting them in the cabinet, they were at 1.4 amps and they hot a little hotter than I like, so I turned them down to 1 amp,.
If you have a smart phone then you likely have a basic LUX meter. I have a handheld lux meter (cheapo ebay) and an App on my phone and honestly I think the phone is more accurate. not a PAR meter or spectrometer , but hey, use what you got right.Yeah, I wish.

Yeah, I tried the phone thing, apparently mine won't work as a light meter.If you have a smart phone then you likely have a basic LUX meter.

I would love to be able to afford one of those Sekonic C-7000's or something similar, spectral colour graph and ppfd.
I'd just like to be able to get one of those Apogee quantum flux meters....Yeah, I tried the phone thing, apparently mine won't work as a light meter.
So each strip is 500mA ?BTW, I found out all but one of the voltage/current displays I have are WAAAAY off (like double the actual amperage).

yeah, that's what it looks like.So each strip is 500mA ?
Right now I'm at 150W to the lights, plus power supply losses - probably ~170W at the wall. Was gonna grab another set but they are currently sold out....Well, I just received my 30 strips. Time for me to get building a 720 watt 4'x4' light I suppose! Woot!
NF, how many watts are you pulling from the wall with yours?
I'm not really up on all the different Meanwell models, but I'd look for a 200W 700 mA CC driver - that should go to at least 285V, and you can put ten strips in series on it. You would need three drivers for all thirty strips.What would be the best power supply (or multiple power supplies) to power 30 of these strips? I am used to constant current power supplies to power cobs, but not sure what one(s) to get. Theses strips are new technology to me.
The constant voltage (24V) power supplies I am looking at are only in the 85-89% efficiency range. Even the Meanwell power supplies. The constant current drivers I am used to using are all 93+% efficiency.
