Just started posting not to long ago. Rather see someone test and what not than someone say it's bad but there's no side by side. I'm thinking to go LED or just stick with DE HPS. I need about 10 lights right now
lol
You can do LED for quite cheap nowadays friend.
You'd be best settled ordering as many boards as you'd need to fill your space, (mega discounts on larger quantities) from China. Meiju, kingbrite, R2T qre your best bet. Shipping won't be much for just boards.
Buy several Mean well HLG 480's or 600's locally for warranty reasons, some angle aluminum from a website I can hook you up with for dirt cheap aluminum, build them, plug in the drivers, and get to growin.
I promise you, it's very easy to build a light with the advancements that have come along recently.
