Anyone have any experience with their lights ? They look like a really good deal and their PPFD specs are pretty impressive.
Im looking for cca 800 PPFD coverage and their lights look impressive, at least on the paper, Im thinking to ditch the DIY altogether because at the end the price for Budmaster lights and my DIY 11x 35900@1050mA setup is marginal.
