Thanks

Its 75w or so and can be used with automatics(20-24h light per day) but for normal 12/12h grows you would need more of them. They are also a few years old and f... expensive.
Better get a few 2ft. EBgen2 strips from digikey and a siutable 20v driver. These strips need no heatsinks and have poke in connectors, so no need to solder anything. Simply mount them on a frame, connect them in parallel and you have a light weight fixture with 175lm/w. These strips are available in 1, 2 and 4ft length and its pretty easy to build it yourself.
9pcs 2ft strips are only ~70$ and a HLG-120H-20A costs ~48$. Single core awg18 wires, a few selftapping screws, a frame made out of alli L-channels and a few hangers costs maybe another 50 bucks. Thats a 135w light with ~176lm/w or 2,5μMol/J efficiency. Enough for a small 2x 2' area. You could build it with only 6 strips too but efficiency goes down to 2,2μMol/J in this case.
If you consider to go that route I recommend to visit ledgardeners website. There are a lot of wiring examples available and a calculator tool for different areas if you have another tent.
