Wow this turned From a simple question to a hostile thread . lol.
OP
hi u guys can someone tell me what is the difference if my light would be on a 110 or a 220 volts plug , my monthly bill wouldn't change wright to my understanding its just power voltage , what i mean by that is if my 1kw light is on 110v plug lets sey it needs 15amp breaker than if it would work on 220v it would need less breaker amperage , because of easier power flow , idk maybe someone of you know the answer and will let me know, thanx
The truthful answer
Answer is 240 he will need breaker at least the size of amp draw his ballast/s runs on, I dont suggest same size, a little larger wont harm as it is capable of pushing amps and allows an upgrade if needed in the future. The device will only draw what it needs and be fine. No his light bill wont be less, Yes resistance will be lower which will mean lower heat issues and less of a fire risk.
As well keep in mind at the higher amps and voltages to beware of any water danger and keep the ballast far from it, whether 110 or 240.
The post below yours explains why most of what Von has said till now can be summed up as sewage waste. Well to be honest his apology was well placed, but then back to his thought a commercial grower may see a lower bill crap.
As for hostile, well he got butt hurt for being proven wrong and became crack whore ugly afterwards. Ignore a commercial grower may see crap. If you could defeat wattage used, Consumers would change bill rating to match. They are not in the business to give away anything. Beyond all dont try the I will sneak power trick either, it will earn you a degree of hardknocks.
I was going to say something else, but decided this is where it shall rest. I can remember now, why I forgot my user name a year or so back.
Again self edit
