Been a little while! I've been revisiting my build idea and could use some help validating what I've learned
side question: can you run a driver that lists a fixed voltage at a lower voltage? what's the difference between an AB driver that does 27~56V or an AB driver that is 56V
So I'm looking at 4 of these
560mm BXEB Gen3 Thrive 4000k 2690lm, 138 lm/W, 20.3Vf, 960mA, 19.488 W

running in series parallel, 2x2:
what's the math on series parallel?
I'm under the impression it's adding the volts for series, and adding the amps for parallel . in this case double for both? if that's the case:
Amps
test: 2x 960mA = 1.92A
max: 2x 1.92A = 3.84A
Volts
2x 20.3V = 40.6V
Watts
test: 38.976W
max: 77.952W
Then I think I need: 40.6V, 1.9-3.8A, 78W
I found:
XLG-100-H-AB https://www.digikey.ca/en/products/deta ... B/10129183
100W, 27-56V, 2.1A
XLG-150-H-AB https://www.digikey.ca/en/products/deta ... B/10222586
150W, 27-56V, 2.8A
The 150 gives a bit more room but doubt I could use it. To me the 100 seems like the best option.
Does this sound right or am I out to lunch? I've been trying to learn in the off-time but it's not coming fast
As always, appreciate the responses!
Driver Selection Again :)
A "Fixed" voltage MeanWell LED Driver still has a Vdc output operating "Range" set by the Driver's circuits and listed in their datasheets, for example an HLG-100H-54AB has a CC "Voltage" Range of 27 - 54 Vdc
The numbers look good. Good luck.
4 Strips of 560mm BXEB Gen3 Thrive; 4000k 2690 Lm (~ 43 PPF), 138 Lm/W (~ 2.2 PPE), 20.3Vf, 960mA, 19.488 W
Total of 10760 Lm (~ 172 PPF).
19.5 W * 4 strips = 78 Watts (50% of Rated Max Current, ~ 172 PPF)
78.0 W * 1.25 = 97.5 Watts (75% of Rated Max Current, ~ 215 PPF)
2-Series = 40.6 Vf
2-Series x 2-Parallel (4 Strips total) = 40.6 Vf, 78 Watts
