i get what your saying but I think they said lights would be dedicated separate service ?everyones enviro is different cap,i run the same 9kw with no a/c all winter and it only takes a 2.5 ton to cool it in summer with 90f temps outside.plus one dehuy pulling half the amps yours does and I run at 35% rh I think @Myco answered all the op's questions pretty well as far as the differences between 120volt and 240voltMy AC alone pulls 45 amps on start up and it is a portable 5 ton unit that barely keeps up with 9k in the summer. Each 1k light is 4.5 amps running on 240. A dehuey is 8 amps. I haev 2 of those to keep up. Most residential dehueys are 110. You should leave 10-20% free on your breakers at all times, includign your main breaker so forget about 200 amps start thinking 180 amps.
With 40 lights you are gonna need 15-20 tons of cooling. There is no fuckin way you can put all that on a 200 amp service. Sorry.
NoOlyver,
Are you saying you put 36 lights plus the air conditoners, dehueys, etc. on a 200 amp panel?
If you purchase a titan helios 14, you may have issue with electrical inspection, CEC requires all enclosures that are NEMA rated be 14AWG thickness, the helios is 20AWG, pretty thin considering, don't know why the couldn't have built a better enclosure.
I think there is some confusion going on in this thread.
By running 240v as opposed to 120v you ARE allowed to run more lights off of a given circuit/panel.
Amps = Watts/volts
Watts do not change, voltage and amperage does. The amount of amperage is what dictates how much power can run through said panel.
Running a single 1k at 120v, pulls 8.6 amps. 1000/120 = 8.6 amps.
Running a single 1k at 240v, pulls 4.3 amps. 1000/240 = 4.3
So with a 200 amp panel, assuming nothing but lights are going to be on said panel, it is recommended to not exceed 80% of circuit capacity. So we're working with 160 amps. If we divide 160 (total amps available) by 4.3 (a single 1k at 240v) we get 37.21. So basically, 36 or 37 lights. If we were to run the same lights on 120v, we'd divide 160 by 8.6, as running at half the voltage, we will double the amperage... this works out to 19.28 lights... so 18 or 19 lights.
It is an obvious choice when it comes to running lights on 120v vs. 240v when running more that 1k or 2k... and even then, it allows you to have more wattage on a specific circuit. Smaller circuit size, which means smaller wire. It allows you to more efficiently wire your setup, it doesn't affect the actual efficiency of the lights or power consumption.
Hope that all makes sense, good luck, and be safe!

Edit: voltage varies up to 250v depending on specific area, always calculate by 240v, because the lower the voltage, the higher the amperage. When considering larger loads, this does make a difference, and you want to stay within 80% of maxing a circuit with a full, constant load.
Thanks to everyone for the answers! I've heard conflicting answers to this question. Has anyone actually seen a flower room with 16,000 watts worth of lighting running at the same time (not 2-8,000 watt rooms running on a flip) on a 200 amp panel?
Hi DO IT, how the heck are you doing.
@DO IT
Go big or go home eh?
Or in your case... Go big AT home!
Cap that's why I was telling you I needed your bennies in larger amounts ;).... When we guna see them 5 or 10kg bags or buckets???
