B&H has herds of em and most aren't expensive.

Re balancing lighting loads.
Bigger isn't always better. Canada and the US both use 15 amp and sometimes 20 amp appliance circuits. Although the voltage is "110" volts it can vary 10% legally (up or down) 120 is usually the upper limit. At 120 volts 1000 watts draws 8.33 amperes, @ 110 volts 9.1 amps. A circuit that is fused for 15 amps should only be used at 80% of it's capacity (12 amps)

What about the lamps, a computer or the TV they all draw something. The lights aren't always the only load in the circuit.

It would be embarrasing to plug into someones recepticles and clear the fuse or breaker. I seldom use more than about 800-950 watts total.

I spent this morning changing out 15 amp breakers for 20's because some engineer couldn't multiply
