Volts and the effect Q.

I believe America uses 110v and were i am uses 240v.

Is one more efficient than the other? Can it effect light output?

We have 110 and 220v in America. The only difference is that the higher voltage circuit can supply twice the power on the same circuit.

It doesn't affect output. If a 1000 watt lamp uses 10 amps on a 110 circuit it only uses 5 on a 220.

appliances like full size electric clothes dryers run only on 220 and use a different wall plug than 110 to differentiate.

100% correct. There are no power savings to be had either way. You can run 2-1000W HIDs on 220 but only one on 110 tho you can plug lots of lower wattage things into the same circuit that the 110 plug is feeding the 1000W light. Oscillating fans, air pumps, exhaust fans etc can be plugged into the same 15amp 110v line your 1000W is on as long as you know what all the various device are rated at. On a double socket you can have the 1000W plug using one and a nest of plugs for small devices plugged into the other plug and still be below the breaker limit and not causing any problems at all.

Go buy a basic electrical code manual for 1st year electricians and educate yourself to stay safe.

Good luck!

o im not playing with anything i should not play with oldmeduser.

I was just a wondering.

Thank ya both.

It is a very good idea not to load more than 80% of the total amps available. With a 15 watt circuit and 1000 watt lamp I would be very careful of adding stuff as you are 66% there aproximately already.

A 6" fan is unusually at least 1 amp. So a couple more fans and you are safely maxing the circuit.

Just for example. I run 2 600's and 2 inline fans and 4 circulating fans on a 20 amp 110v circuit.

If it was 220 I could run 4.

Higher voltages are more efficient.

Also... if a 1000w runs normally at 8 to10 amp on 110v then when it first turns on the amps spike up to 13 to 15sh amps, which will trip the breaker...

I run my 1000W on it's own 15A circuit and it's never flipped the breaker. The only other thing on that circuit is a 5W air pump once in a while. I run that in fresh jugs of RO water to charge them up with air before use.
