Garage Lighting Replacement


The lighting in my garage is pretty lacking.

I have 2 single bulbs (one per junction box) and a 3' fluorescent tube with a melted ballast (another junction box), all on the same circuit.

My question is a stupid/simple one. Can I replace what I have with fixtures containing 2-4' fluorescent tubes without overloading the circuit (Circuit has a 15A breaker).

Using the equation power = voltage x current (and conversely, current = power / voltage) I get:

Power = 32W x 6 tubes = 128W
Voltage = 120V

Current = 128W / 120V
= 1.1A

According to the calcs, it looks like I'm good to go but I might be right out to lunch. Thought I'd better check with the experts first!

Thanks in advance!

15amps is good for up to 1800 watts, so you are fine with that small amount.

All looks great as long as those lights are the only thing on that particular circuit.

I'm going with 6" cans & 13w CFL reflector bulbs in my garage
I did a test setup in my great room & they really put out a lot of light @8' up

Can lights look awesome in garages! (Must be a guy thing). Depending on the weather, they are much better than fluorescents as long as you install enough of them.
