Hey Jonny, My guess is @Bosgrower made a typo with the 8000 watt recommendation. He likely meant to type 800 watts.

You're absolutely correct ... late night typing error ... should have been 600-800w8000w of LED eh? Made me smile. 'Preciate that
No need to steer this fella down the wrong path. The first half of your recommendation wasn't bad. 2x 1000WDE HPS would be a great option. I was even onboard with the 4x 315w CMH for veg only, but you got into the weeds after that.
8000w of LED fixtures? Not a chance in that space. I assume you're using idiotic "LED equivalent" conversion numbers that are meaningless and should be referenced by no one because they aren't real numbers. Now that we've addressed that let's talk about telling this fella he needs to spend $750-$1500 for a quality light. One word: Absurd. He could install 2 SF-4000's in there for about $600/each and be done. That's considerably less than $750-$1500. To dig into that further let's discuss Alibaba. I ordered a 660w Q board that I presently have mounted in my flower room with 2600w of HID lighting. I paid $504 for the unit from Alibaba. It arrived faster than the SF-4000 I ordered from Amazon by 3 days. It pushes considerably more power than the SF-4000 and has the same LM301b diodes and mean well drivers, but don't allow that to skew your predisposed notions about the legitimacy of merchandise for sale on the platform.
$504/with shipping. About $264 cheaper per unit than the $750 quoted above.

Please bear in mind you''re looking at a 5x5 space. QB lights PAR values are insanely center weighted. You'll be MUCH better off with a 47" x 43" (for example) bar style fixture. This one happens to be a 10 bar fixture but there are 6 and 8 bar models as well. Just understand that the majoity of all of the fixtures out there target a 4x4 flower area so shop or build carefully

Well said. My 660w Q board has zero footprint outside the dimensions of the board. Plants that are not directly underneath do not benefit for the most part. Learning that the hard way in my flower room presently. I really dig the bar builds. I'd love to do the one GreenGene put together, but $800 is a bit too steep for me at the moment.

This is the PAR map for that 800w 10 bar fixture. Unlike many of the fixtures out there it's rated for a 5x5 flower footprint. Granted it's $1,099 but it ships from upstate NY and has a 5 year warranty. A similar fixture from China would save you 200-250 after shipping but good luck with timely replacement parts if there's a problem.
