No mystery Watts are not . KilloWattsperHour (kWh). The two are entirely different. 200 watts is 200 watts. However, 200 watts being driven at 1400mA cost more after 12 hours than 200 watts being driven at 1050mA, by a 25% savings alone. So after 12 hours of running a meanwell HLG-185H-C1400B driver will cost based on amps being drawn.
HLG-185H-C1400B HLG-185H-C1050B
1.4A x 12 = 16.8kWh 1.05 x 12 = 12.6 kWh
1 month 30 x 16.8 kWh = 504 kWh 30 x 12.6 kWh = 378 kWh
12 months 12 x 504kWh = 6048 kWh 12 x 378 kWh = 4536 kWh
cost per kWh $ 0.16 $967.68 $ 725.76
average cost savings is $241.92
not calculated is cost of cooling.
Higher voltage has less drop over distance.

I think where everyone is confused is the 200w part. Maybe it should be said that the cobs produce less light at 200w?
The part were having trouble with is this 25% savings in electricity costs simply from switching 1 200w light to another 200w light.

I was taught there are three Proofs, Documentary Proof; written facts;, Theoretical Proof; theories untested; Actual Proof; results based outcome. Of the three Actual Proof is the most important.

If you want to form an informed opinion of the GrowGreen board you can CO-Op a board or two or you can contact this company -> https://tophspcb.en.alibaba.com/?spm=a2700.8443308.0.0.mMeK17
ask for Jeff Wei and he will provide you with 13 GrowGreen boards for a fee of course.

This is the same company that makes the Quantum Board. Issues of genuine Samsung diodes, quality of construction, or other issues relative to the supplier are non-existent.
The Grow Green board is MY design, and I share it openly just as I do all of my ideas.

@VegasWinner Do you have proof this Jeff Wei is the producer and maker of the HLG QB board? Just want to clarify this claim you made.

A typical 200w cob setup uses a 1400mA driver with 36v cobs. It draws three amps to cover 2x2 with 200 watts.
No. it does not. A 200W (four 36V cobs) setup on a 1400mA driver draws 1400Ma @ 144V from the driver, and with a properly matched Meanwell 200W driver, the efficiency will be ~93% and the current draw at 120V AC will be (212W/115V = 1.84A, not 3A. The Meanwell spec sheet for the HLG-185 series lists the exact same wall current draw (~2A @115VAC) for all four versions - 500 mA, 700 mA, 1050 mA and 1400 mA.

Please stop lying.
With A GG uses a 1050mA driver drawing two amps less amps same 200w .same coverage.
Same amps - 2 amps for both.

Two amps per hour is less than three amps per hour. More efficient use to cover 2x2 with 200w per hour. You are paying for the power supply on an hourly basis not the cob. The driver is connected to the wall. The lower operating amps of the driver means the driver makes less heat thru thermal resistance of the wire using the right hand rule for current. Less current less resistance greater efficiencies. Electronics operate more efficiently the cooler they are power supplies are no exception.
Same amps at the wall. Same power out. Same efficiency. Its right there on the spec sheet. If yours was drawing more than two amps from the wall, but only delivering 200W then ITS BROKEN.

If you are running 240 320 and 480 drivers they are very large heavy because they use more amps.
They use more amps because they deliver MORE POWER.

All 185h drivers generate 200w at various current draws. The lower the amps the more efficient less heat. A 350mA can generate 200w but the Vf is 257v a 500mA is 400v a 700mA is 286v a 1050mA is 184v a 1400mA is 143v.
All have the EXACT SAME EFFICIENCY when running at full rated power. Output current is not relevant to their efficiency.

Stop lying.

The lower amp rated drivers use less energy. The higher amp rated drivers use more energy to do the same watts.
No, they do not. Read the spec sheet.

Stop lying.

You pay for amps used not volts used. Power is delivered at a constant voltage. You are charged by how many amps you carry on those constant volts 120v for usa or 240v commercial. 240v is more efficient than120v lower amps again.
Amps are MEASURED but you are billed by the kW/h.

A 1400ma current is heavier/more than a 1050ma current both traveling on a 120v circuit or a 240v circuit.
Neither current is on "120 or 240" the 1400 mA is at 143VDC, and the 1050 is at 190VDC. READ THE SPEC SHEET. Both pull 2 amps at 115VAC or 1 amp at 230VAC or 0.85A at 277VAC. Its right there on the spec sheet.

If you could choose you would choose the lowest rated amp products if you want a lower power bill.
Are you drunk?

BWAHAHAHAHA!!!!

Now I know your full of shit. What does the right hand rule have to do with thermal resistance of wire? Go ahead and google it, cuz you CLEARLY have no clue what the right hand rule of current is.

You'll see slight improvements (fractional or single digit) in efficiency running the drivers at higher voltages (this doesn't depend on the particular LED) 1-2% from US to UK

The input current ratings are typical per the voltage listed, they will depend on the load, the circuit will only pull and deliver what the load is calling for.

A HLG-185 draws ~200w, fact!
It takes AC from the wall and convert it in constant DC.
But this does not matter because it only "sucks" AC from the wall.
At 220v ~0,9A, at 110v ~1,8A, DC output does not matter here, no matter whether it delivers 500mA or 1,4A. Only power factor correction and internal circuits are different so only 2-3% difference in effiency. See screenies below!
There is by no means a 50% gap in kwh draw from two different HLG-185's.
Perhaps someone hijacked you electricity or your refrigerator was open all year round ...
Remember! Power supplies consume no dc, they supply it. They consuming only AC and all HLG-185 have the same AC power draw within 2-3%.

BTW, dimming effects effiency like you can see in the second effiency vs. load screenshot.
If you dim your driver below 20% and keep your ear close, you can even hear the inefficiency.

This is just beyond hilarious. It's the same "high side switch" drama all over again. Then he too got livid that we were all wrong and annoying. Or when he insisted that dimming a 10V PWM driver would never work without an extra 12V source.

It's baffling why some people feel the need to pretend they are guru's at something when it's so overly clear that it's something they just started with. Probably because his aim has always been to sell ... ehm sorry ... "DIY CO-OP" stuff to people. Better not let on that you're really a noob then.

What's even more worrying, I think he actually still does think he's right. Even after a dozen or so people explained how it actually works. It will take a few months before it sinks in. Took him well over half a year to finally understand how 10V PWM dimming works.

Would like to know in which area he has made his engineer? Certainly not in electronics...

Thanks for posting this. It's why I avoid dimming below 50%.

I had to put a bunch of people on ignore because they lack understanding. One in particular has gotten my private email address and attempting to fight with me via my private email, address claiming some higher standard while lying to get that said email address. This is the quality of people on this web site promoting the major sellers here.

Clearing the air; he willingly gave me his email address. Then he gets upset because I respectfully related the same concerns everyone else has here. His accusation of lies are themselves untrue. I have nothing to lie about! Lol I represent no lighting or any other company at this time.

Dude has anger management issues. All those who want to work with him need to be aware that he doesn't handle criticism or questions, nevermind well.

Good luck!
