   I have a "expanded" garage that was expanded by punching out the back 
wall into the backyard another 16 feet, the end result is my garage is 
24ft. wide by 38 ft. deep.  I wired this up with lots of lights and I mean 
lots.  I have a total of 14 4ft. 40watt fluorescent bulbs and 4 8ft. ?watt 
bulbs.  Thats a lot of lights most are 2 bulb fixtures placed right over a 
tool, the 4bulb fixture is over the workbench.  I was noticing a few nights 
ago while outside that my garage is quite bright but I like light over a 
tool or bench or motor.  If it matters, the exact count of fixtures is 5 
2bulb 4ft fixtures, 1 4bulb 4ft. fixture, 2 2bulb 8ft. fixtures on a maybe 
20Amp circuit.

   I never rewired the garage for this and I am wondering if I am 
overloading the wires.  What is the amperage of a 40watt fluorescent bulb ? 
and a 8ft. bulb of ?watts.  Also what is the wire gauge for a 20Amp 
circuit, this is a old house with a new looking 20Amp breaker, I have not 
checked the gauge of the wiring behind that breaker.

   I can turn on my shop vac and band saw together, or my grinder with no 
dimming of the lights.  My radial arm saw and shop vac causes the lights to 
dim for a second so thats overloading a little.  I hardly ever blow the 
circuit breaker and only when a friend and I are running multiple 
tools.   I don't want a fire, should I do something about this ?

  I have a 220V circuit running the stationary tools, a 120V 25Amp circuit 
that my Mig is plugged into and all the lights and few small tools are on a 
20Amp circuit.  I was thinking of taking a few lights and moving them to 
the 25Amp circuit but the Mig requires 25 on the thicker metal.
