Awesome post with lots of information and no rambling. I had to give you a reputation point boost for that, lol.
The last one took a little more than a 15 amp load and popped.
Apparently, they're manufactured at the WalMart level of quality and standards. A while back I stumbled across a thread about (easily and cheaply) repairing them with upgraded components. It was on one of those electric car forums and people were testing their chargers - that were well within the allowable load range for the Kill A Watt devices - and melting bits of the things by leaving them connected overnight, lol. That's where I read the bit about how to calibrate them. IIRC, there was something about being able to set it to 240(?)V mode, too. Anyway, the calibration procedure is initiated by a simple button combination - so be careful not to press more than one button at a time.
Here is the total wattage with all the lights on. They call it a 450...so maybe rounded down.
Or maybe the "450" figure is without considering the UV bulb - which is how I'd do it - and allowing for losses in the power supply (et cetera). IOW, 450 watts actually reach the COBs and mono-color LEDs. That is, of course, just a guess. But my last Lumatek 400-watt ballast used a 400-watt bulb... but consumed something like 471 watts (IIRC).
Amp draw...you can tell that the people who designed these lights grow cannabis. I see what you did Amare
Lol. Yeah, they are in league with your electric company and your house's wiring.
Hmm... Interesting. According to your pictures, the COB switch pulls 305 watts and the mono-color LED switch pulls 172 watts. That's 477 watts. But you saw 466 watts with both switches activated. Oh - all the fans run off of either switch. OOPS, I didn't catch that when I posted my numbers. Do you suppose that means all the fans only draw 11 watts?
And here it is through the side air vents.
You're getting some "side-scatter," too, I see.
Since the actual wattage was 481 and we got 371 grams off of the first plant... that brings it down to .77 gpw.
If it was me doing the calculating, I would NOT count the UV bulb. Yes, it's a light, lol. But I consider it more of a... modifier. It's a narrow-wavelength, low-wattage, low-intensity fluorescent bulb. My
guess is that your harvest's mass wouldn't be less had you chosen not to use it. Its purpose, AfaIK, was to invoke a protective stress-response in the plants.
Therefore, I'd call it 371 grams per 466 watts, or .796 g/w. Or .8 g/w if you wish to round it (I would - it looks better
and .004 gram won't get me high).
Still not a bad number at all.
13¼ ounces is a nice bit of cannabis.
I think the way to get the most gpw it could be done in a 4x4 and a SOG. That's not our style right now but I could see us doing a 90 day SOG some day. Just for kicks setup both rooms and have two giant Seas of beauty. I could see us easily getting 1 gram per watt in both rooms.
You could try playing around with the lenses - maybe removing some whilst keeping others in place to tune the footprint (and intensity across same). Have you looked at the PPFD or whatever those diagrams are that show the light's intensity at a certain height? They ought to have one with lenses and one without. You'll notice that the intensity doesn't have quadrilateral symmetry either way, because the lighting components are set up as two rows of three sets.
When you're chasing yield, it sort of becomes the priority over other things - and those other things are important, too, IMHO. Type of effect, length of same, potency of same, flavor, aroma... Strain choice is a significant thing. As you mentioned, you could go with a SoG - perhaps nine plants per square foot in those square (as seen from the top) pots, or pack in as many two-liter bottles as you can (which might be a little bit less than 9/ft²), filling the grow space with uniformly-sized clones that have decent root systems but received little or no vegetation time after they left the cloner, basically going straight into flower and shooting for 10-13 grams each. IDK if that would do it or not... Well, let's see... If you could get 9/ft², and manage to average 10 grams per, in a 4'x4' tent, that'd be
1,440 grams, lol, or about 51.4 ounces. But that strain would be a heavy indica, methinks. I'm not at all sure that I wouldn't much rather have half that much of a good sativa instead...
Now here is the purple kush reveg under it now. She is showing some beautiful flowers so far. Love the way they look.
I tested the off brand LED that said it was comparable to a 900 watt HID...well it read 253 wall watts. Well then.
LMAO @ a 253-watt "900 watt HID equivalent" - I hope Canna doesn't let you open those spam emails that advertise extreme err... growth. They probably don't sound half so ridiculous.
OtOH, that's ~$1.27/watt - and that 450+UVB costs, what... a grand or a little more? IF that other panel is reasonably efficient (low electrical losses) and manages to produce a halfway decent intensity, it might actually be... not too bad of a deal. I'd consider it a "250-watt class lighting device," though, and if it performed better than a 250-watt HPS, I'd call it a win. If the quality was high enough to last through, IDK, three years of continuous grow room operation, at least.
Wouldn't mind having one a light mover where that one sits currently and get more coverage...hmmmm.
Years ago, I had a Sun Circle that had two HPS and one MH. I'd like to see such a setup with a HPS, a MH, and a high-quality LED panel (probably an
Amare Technologies one). The size of the MH would depend on the wavelengths/intensity of the LED panel; maybe the same as the HPS, maybe the next size down. But IDK that it would produce any better than a good LED setup (or a good HID one), watt for watt.
That's one thing I like about Amare' light as you see more natural color.
Running just the mono-color LEDs, does your SE450+UVB's light output appear to be ever so slightly blue? That's how this one is, and it's really pleasing to the eye. Adding the COBs seems to, IDK, naturalize(?) the color quite a bit - but I like the bluish a little better. Would probably make a great all-around light for the home (and a prohibitively expensive one - when it comes down to it, I could read with a candle... and save the LED for growing cannabis :rolleyes3 ). I had to throw in a little rambling, otherwise y'all would wonder if someone hacked my account
...
BtW, your pictures/plants look beautiful.
for the info on the light.
I did some research and the Amare gets some amazing reviews. A little pricey, but hey, what the hell, I only have to buy it once and you only get what you pay for. :
You go six days,...no cigs, you rock !!
So this one was just wanting to have a reason to use it.
Stay classy. 
Second place ain't nuthin' to sneeze at.
