How many drivers do you have, and what size area are you looking to cover?

8 drivers . i usually use 1 light per plant. the 4 cob cxb3590 lights do not have as good of spread as quantum board style or the bar style lights like geek beast pro . i use 2 geek beast pro lights to cover 3 plants on a ten foot long eight foot high vertical scrog. i also use three board budget leds one per plant, so three per 10 foot long eight foot high wall but the spread is not as good as bars. i have 8 of the hlg185-1400 drivers

3 of these 4ft Samsung strips HERE in series @1400mA, or 6 strips @700mA in a 3Sx2P arrangement will give you about 32000lm/500PPF per driver

I have a question for the experts here.
i have some meanwell hlg 185-c1400b drivers from my old 4 cob cxb 3590 lights that i am not using now. what would be the best flowering leds that can use these drivers? I prefer better spread than light intensity since i do vertical scrog. I have not stayed current with building lights and just repurposed my 4 cob cxb 3590 lights into 8 cob veg lights with hlg185-700 drivers.
i started using the samsung led strip lights in flower and love the spread.
I would like to repurpose the 185-c1400b drivers into some newer style lights using strips or quantum board style .
thanks for any helpful input!

2 parallel strings, each with 3 fseries strips in series would fit pretty well. 30ish watts per strip.

23.19 from digikey 7.0078 from arrow . thats a pretty big difference!

Around $15-$20 is where they normally sit, but those strips were $3 a week or two ago. Arrow has times where their prices fluctuate by up to 90% off, someone posted earlier in this thread it has something to do with inventory space management I think. I keep one of varied strips/drivers in my cart then check in every now and then to catch them when they are cheap because they don't last long.

Dont appear available, and are not $7

The 3000K ones are still at $7, the 3500K ones are $13 and have 232 available to me, maybe a regional thing? IDK

*edit - NVM just seen you linked the double row ones:oops:

sorry my post was not clearer! the same part number for the one mma posted is 23.19 at digikey. I appreciate the input.

$22 per strip is still below $1 per watt. Pretty hard to get lower than that.
Higher powered cobs or strips require bigger sinks which ratchet up overall cost faster than anything else. Long strips and heatsinks shipping adds to costs as well
If you buy 10 plus the price is at under 18 per strip

i understand.
when i built my cxb3590 lights i did a ton of research. my first four were a real pain using heatsink usa sinks. i had to buy a drill press etc.
the next 12 i built using the pin heatsinks, were easier, way lighter, and cheaper. the costs these days are better but even back than arrow usually beat digikey by a wide margin. that was my point.
these f series strips are a great deal either way and i appreciate the help since i didn't have the time to do all the research on what is the best bang for the buck now.
i already ordered everything to build my first three lights to see how i like them. I went the cheap route with the single row from arrow in 1120 mm.
my reconfigured 8 cob lights running at 700 ma should cut my electric by a nice margin and if i can reuse some or all of the old drivers without spending alot building decent lights it will be a win all the way around.
i spent about 250 to make my first three lights which is about 600 watts!

Hey guys!
Most of the times i know my led drivers but this is somewhat especial:
Im looking for low amps (less than 200mA) high voltage (if possible about 100V) and if possible also dimmable. Hoping to set up some UVB for a friend and these diodes taje very low amps. Anyone have know aby good options?

XLG 20 could get you there if you do 2 strings in parallel. But I've shopped a lot of drivers I think it's pretty rare to see such high voltage on a low wattage driver.

i am assuming there's a good reason you don't want to run any in parallel?

Uvb diodes have very low max amps and the ones in looking at are china made. So if i lose a string (due to my shitty solder work or my buddys clumsiness or whatever) ill either break something in the second string and/or burn the shit out of the cannopy due to double output and low hanging height. He grows with buds reaching the light.
Maybe if i do 3 strings.... Ill send some pics when i get it ready.
