From what i have read the max voltage for Gen2 strips is 60 volts (please check) i have built a light using a meanwell i used a clg 150 20c as i found it cheap on ebay for 10 strips but i used the ppf calculations instead of watts this works well for me 36 PPF per strip 20 PPF (Cuttings) 40 PPF (Veg...

Thinking of adding some far red LEDs bit not sure on how many and what sort room size 72cm X 72cm just want to use at end of day to put plants to sleep any help appreciated Hi Stu I havent had time to be on here often, for end of day spread is important. I developed 730nm Buddies for this reason. h...

Led driver HLG 60h-20b
Using a POW R2 to measure watts
LUX meter is CEM DT-130
and yes fairly uniform throughout

i missed a 0 off the scale should have been 50,000 not 5000

@P@PeteR_1


just took some readings 33 watts at the wall

@3" 195
@4" 175
@5" 165
@6" 155
scale x100 5000
strips spaced 80 mm apart

@P PeteR_1 thanks for the reading have just got a lux meter and will take some readings from it at different distances and post them up i have been running these for 5 days and very impressed with the strips for the wattage just a thought seen that ppl run them with in 3" off the canopy so will take...

@P@PeteR_1

Thanks was using your calcs for that so 30w set at wall have a sonoff POWr2 not one for measuring after driver and dose the height look ok at 3-4 inches from top ?

Thanks Stu

i have 6 bridgelux BXEB-L0280Z-50E1000-C-B3 for a bonsai mother and clones will this be enough for a 280 x 650 mm grow space ? looking at the ppf calcs .28x.65 = 0.18 m2 1.8 * 40 PPF (Veg) = 72 PPF / 18 PPF/Strip = 4 Strips think this will depend on height of strips from plants from my understanding...

Ok thanks got it now so the meanwell are a lot better option to be able to control the outputs then

Thanks Stu

so they can be dimmed and used at correct voltage ? they are £30 -£40 cheaper than the meanwells but discontinued models and in stock
