That driver is not a great choice for 20-28V strips as the driver is not very efficient in low V situations. You want to be as close to the max V as possible for good efficiency and at least within 70% of max. However you could use 2 strips in series and get close to max V. Yes, your recommendation...

I don't use Parallel / Daisy Chained circuits but if it's wired Parallel / Daisy Chained Circuit there could be; Corrosion at the connectors, Wire ends corroded, Increased Voltage drop across the Daisy Chained Wiring, check Vdc including LED Driver output and or PCB traces are damaged if there are m...

First of all, thank you for your reply! I have already grown indoors in a 40x40x120 growbox, but I had used various CFL lights, however now I wanted to try this experiment. Staying on 20/30 watts and 10 strips; which driver would you recommend me? MeanWell LED Driver; XLG-50-AB; 22 - 54 Vdc, 50 Wat...

Thanks for your reply! Well, so I guess I'll go with x10 strips. About Parallel & XLG-75-24-A: It provides 3.1A, to run x10 strips, it makes 310mA per strip, right? Wouldn't that lower the strips efficiency? And lower the lumens as well? If the loss isnt't that big I won't mind about that, just wan...

I have a small space (vertical tote) with only 45x40x90 cm (0.18 m2) I'd like to build an x8 (maybe x9 or x10?)

The xlg-h has a derating efficiency at less thab 70% than max or about 40V. Use 2-3 strips in seriec per string. XLG-XXX-H-AB Series are "derated" to ~ 75% @ 27 Vdc but have 100% @ 36 Vdc, Only derated when operating between 27 and 35 Vdc , ~ 75% - 97% respectively... https://ledgardener.com/forum/...
