I run (usually ) 2 HLG 288s (3500k) driven at about 230 total watts these days. I run that in a 2x4 space whereas I ran my ss440 in a 3x3 so it isn't a 1:1 comparison, but yeah my HLG boards definitely outperform the clw. The only thing I will say is that I love how the 440 vegged plants. Super squat, super vigorous and then they'd blow up when you hit em with 12/12 and a bloom spectrum.
You do not own at the very least a Lux meter boss ? you are playing with fire then !Currently experimenting how low I can keep my lights. It's 300-320w in 2x4. Now the lights are at about 6-8 inches from the tops.
I think I should experiment with reflectors too, but I really need a light meter
Ain't no boss
I did buy a lux meter, but it didn't give consistent readings under the leds and I returned it. My phone only measures upto 10k lux too. I think I should be fine even at six inches, because fluence recommends 6" for spydr 2i and my leds are about half the size and output of one. My leds more spread out too. 
The longevity of the bulb is a huge factor. CMH bulbs will last twice as long as an HPS bulb. You get almost the same output of light from 315watts of CMH as you would from a 600watt HPS.
No, you don't. It's almost the same as a 400w hps.
as always thank you for your time
Awesome dude I hope mine come out like that or just close with my cheap LED's man those look great good job!!!
and that is the 2000 watt philzon
Yes I'm familiar with the Philzon Good lights, I went with the WILLS I have for the silence... Man those buds look Tite!!!
eh. There would be no point in buying a 400w hps over a 315cmh tho. The next jump up is a 600watt HPS and 2x 315 CMH would destroy that IMO. I've always looked at my CMH to be about equivalent to 500watts of HPS. Add in the other benefits of CMH (Bulb life, cost of bulbs, color spectrum, heat output added UV) there really isn't any point in going with any other HID bulb if that's the route you are going.

How big is your space?Where are my diode pros out there?
I use to scoff at viparspectra.. They seem to have dropped something to similar to the Spiderfarmer SF2000.
Can someone knowledgeable help me decide on which to get? If either? I need something small to veg with and combine with my LEC 315 for flower.
The XS2000 has 504 diodes pulling 240 watts while the sf has around 600 diodes pulling 202 watts. I can't find the spiderfarmer's specifics.

I'm only considering Viparspectra because of the 20 percent off deal, $224 before tax. I'm afraid there's not enough red and IR light. Open to ANY suggestions.
I would go with CMH to add UV
I would just be flowering in a 4x4 for now. I just need something decent for veg, then plan to combine both lights into the 4x4 with flower. The LEC does real well in a 3x3, just trying to keep it cheap and decent. Not a fan of mars hydro's old fixtures but this line seems like they are headed in the right direction! https://www.mars-hydro.com/led-grow-light/mars-fc-series-led-grow-light/buy-fc-3000-300w-3x3-energy-saving-full-spectrum-commercial-led-grow-light-mars-hydro-for-sale
