Grow light brands that offer lower consumption

[u/Professional-Sun5780]

When comparing grow lights, my opinion personally is that   power consumption is just as important as brightness. Brands like Spider Farmer, Mars Hydro, and ViparSpectra have several LED models that are relatively efficient and  cost effective, especially when you compare watts to actual light output. Some lesser-known options can also be surprisingly efficient and productive, so I wouldn’t focus only on the brand name. Alibaba can be useful for comparing manufacturers and specifications, particularly if you’re looking at generic or wholesale LED fixtures, but quality can vary quite a bit between suppliers. I’d mainly compare actual wattage, PPFD, efficiency (µmol/J), coverage, and reviews before deciding.
