The lights have not let me down yet. Ppfd drops quite a bit at the edges, 3 of these lights in an 8x4 would be better. My only complaint is the specs advertised on the website are different then what is in the manual, the manual shows LM301D instead of LM301H that's on the website. Vivosun tells me the manual specs are correct and that they changed the light a few years ago but didn't update the advertisement.
Even with this issue, the lights perform well and I'm always satisfied with the outcome.
