I've got a 3x3x72 tent arriving Monday. I still haven't settled on a light yet...been doing all kinds of research and it's really frustrating because of the companies that sell them.
I decided I'll double my budget on lights since I want something that may last and be enough for decent yields. I've been learning about different diodes (Samsung LM218B, LM301B, 301H, 301H EVO, etc). Also reading and watching a bunch of reviews on lights I'm interested in.
The problem is these models change every year. Not the model numbers which stay the same, but the components change. They may put in better diodes one year, and take out the better driver. Or put in better diodes, but decrease the total amount of diodes. Even downgrade to generic diodes, but it's the same model number as last year.
So going by reviews and videos doesn't help at deciding what may actually be a good light when they're reviewing superior versions of them. Even popular brands like
Spider Farmer and
Mars Hydro are all over the place cutting corners. Their listings will show one spec in the product photos, and give another spec in the description. So who knows what you're getting.
Sorry for the rant but I'm ready to cut a hole in the roof and let the sun handle this. lol
