How much are you yeilding with 2200 watts of cobs?

Thanks for your input.. Hopfully it won't start a fire.

Theres 10 80watt drivers per light and I'm buying 4 lights so I'm probably not gonna be replacing them all. They're encased in metal so I think I'll be fine plus they'll be in my shed.

Is it not good to run power supplies at 100%?

Best yeild and quality. I can only have 6 flowering plants so i'm trying to maximize yeild in a 9x9 space

I think thats a different company than the one i'm looking at

So I noticed fluence sells their 330 watt light and advertises it for a 4x4 area. They say its meant to be 6 inches from the top of the canopy and will produce PPF: 810 µmol/s and Efficacy: 2.5 µmol/J https://fluence.science/store/spydr-series/spydrx/ Would I better off getting 4 nalite 400...

The 8 bar 640 watt is $410. Probably the same shipping amount. 8 bar without dimming is $375 The 10 bar with standard dimming and no bluetooth control is $500. Its Bluetooth, Not wifi

How does that ss400 compare to the newer led technology? Whats your yeild from two 315's? Is it the balasts that put out most of the heat or the bulbs? I have a two ton mini split for my shed which is probably over kill but if I go cmh it will probably be needed more

Are you getting better results with the 315? I was looking as that as well but I'll need about 10 315's for my space and it seems the led setup from China could be similar in price or less. What led setup do you have to compare to the 315cmh in flowering?

Is this based off fact or your opinion? From my research it seems all these US based lighting companies use Chinese suppliers and mark everything up 100%. Anyone can buy Samsung leds at low prices in bulk and assemble lights. Or you're saying the leds can be Chinese Samsung knockoffs?

So they sent me this file of the inside and they use 10 80 watt Nalite power supplies which would make it run at a max of 800 watts. This is their own brand power supply but do list a 5 year warranty on the parts. Is it ok to drive power supplies at max voltage? I read on a different site that...

they are lm561c's i believe

I found these lights on Alibaba and was wondering what you think in comparison to HLG or fluence lights. I'm thinking about buying 4 of these 800w lights for my 9x9 shed but was wondering if its to much light since i'll need space to move around the plants. Even at 18" above the plants this...

I got a price on this nalite 800 watt light on alibaba for $625 shipped. It uses Lm561c leds. Do you think I can build a better light for around the same? I was planning on buying 4 of these lights to fit my 9x9 space

How do those strip lights in the bottom pic compare to a hps or led builds from HLG? I'm looking to build some for a 9*9 space. How much did materials cost for say 500 watt setup using the strips?

There are some free 55 gallon drums at my local metal pile. Line the inside of them with led strips, cut holes and add dc fans for air circulation . Maybe i'll try it.

Was wondering if anyone have tried making a circular grow space and lined it with led strips like in the attached picture? Do you guys think there would be any advantage in yield with a design like this? Thanks David

HLG advertises their HLG 550 v2 500 watt ($1049) as a direct replacement for a 1k single end Hid. Do you guys really think it really competes with a 1k HID or is it mostly marketing? There's sellers on Alibaba that advertise 480 watt quantum based LM301B's for around $350 plus shipping...
