It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
At 120 volts a 15 amp breaker can be loaded to 1800 watts before it will trip. If it is a continuous load then the electrical code states that it is only allowed to be loaded to 80%. This will be 1800 x .8 = 1440 watts. If the voltage is not 120 volts use the following equation Watts = Amps x Volts. Amps being the breaker size that is to be used.
One breaker in the North American electrical system will supply 110 volts. Two adjacent tied breakers will produce 220 volts.
If the power requirement is 120 volts it will be connected to a single pole breaker rated at the amperage requirement of the air conditioner. If the voltage of the air conditioner is 240 volts, then a two pole breaker will be required.
The equation that you are looking for is I = W/E. Amps = Watts / Volts.
Since baseboard heaters come in many different wattages vs. lengths I guess the best answer would be, you can load up to 2880 watts of baseboard heaters on a 15 amp two pole breaker at 240 volts.
50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.

Check the current draw that is on the label of the ballast.
Does it surge past 120?? Drops are due too the fact that there are too many outlets or devices on one line. Trace the line that you have a voltage drop in and find which breaker it is, if the line that comes off the breaker is a 12 gauge wire and the breaker is a 15amp breaker you can put in a 20amp breaker. If the line is a 14 gauge line then you must leave the 15amp breaker in place and remove a device from it.
