Quantum board electrical question (uk based)

hey people am new here, my first post so am sorry if this is the wrong place

have had green fingers for a few years now and have recently upgraded from hps to quantum boards, have recently purchased this light

QB288 V2 Samsung lm301B SK full spectrum Quantum Board 600W LED with XPE 660nm

Gotta say am impressed, so impressed in fact that I'm planning to buy another 1 maybe 2... Which leads me to my question. My electrical knowledge is quite limited and I've been doing some reading up on quantum boards, from what I've read it leads me to the understanding that QB's have to be viewed differently in terms of the power they consume. Whereas with HPS Ive always looked at it terms of watts used (rightly or wrongly), it seems with QB's I have to look at it in terms of amps and volts? I currently use 3 x 600w for flower and 1 400w for veg, via 2x 4 way maxiswitch controllers, but all are powered through the same plug with 13amp fuse and have never had any problems. If i was to buy 2 more of the 600w lights above would I be able to use them through the same power set up, or would I have to use another mains 13amp plug? If i have posted this in the wrong place please let me know

Thanks for taking the time to read this, and sorry if my lack of electrical understanding offends you lol

I think you might be getting confused by the way some sellers market their LED lights. Anyway, 600 watts is 600 watts, regardless of it's source. So, you can swap the 3 hps with the 3 hlg, or run 1 hps and 2 hlg, or 2 hps and 1 hlg.

Watts are simply voltage multiplied by current. For example, a circuit that runs at 50 volts and draws 12 amps is consuming 600 watts.

You would have to check the data sheeta for your drivers. Are they meanwell? Since youre on 220? The stated amperage should be half, because the volts are doubled, but wattage will be the same.

I looked up that light and the driver specced is a HLG-600H-54B so the wattage would be 600 and if hes running them at 220 volt then he's looking at 2.73 amps per light.

Would be in the 650 range though.

Good point, the input power is a little higher as nothing is 100% efficient. From the data sheet I get these numbers

Output power 604.8 watts
@ 115 VAC Power Factor is listed as 0.98
Thus I get an input power of about 617 watts at 115 VAC. At 230 volts the power factor is 0.95 so 636 watts at 230 volts.

im wondering about how the meanwells have higher efficiency (96.5 vs 94.5%) but lower power factor (0.97 vs 0.99) at 230V vs 115V

when we look at the reality of *billable* electricity does the increased efficiency at 230V just get sucked up by power factor anyway?

to my knowledge you dont pay the inductive reactive power (had to translate), just the active power.
So what you can meassure on your power meters they meassure and bill too, the active power.
It is your providers problem and he is problably more happy with 230V, as he can push the amps with lower heat trough the lines.
Also the reactive power can be extra compensated, but nothing private customers have to care for normally, done in industry scale.
Can differ from country to country, but thats how it is here and probably in most of the world.

Beside that, i think it should slightly matter if they have to work in buck or boost mode.
Buck, voltage down conversion should be slightly better, but thats not direct power factor related.
