Look on the ballast inside of the fixture. There is an amperage and a voltage on the ballast label. Use this equation to find the wattage. W = I x E, Watts = Amps x Volts. This will give you the answer that you are looking for.

What is the wattage of a standard four foot fluorescent bulb?

The wattage of a standard four-foot fluorescent bulb is typically around 32 watts.


How many watts does heat trace draw?

Heat trace systems typically draw 3-15 watts per foot, depending on the specific type and application. This power output is necessary to maintain the desired temperature and prevent freezing in pipes, roofs, or gutters.


Using twelve gauge wiring how many eight foot fluorescent lights using 110 watt bulbs can you use on one twenty amp circuit breaker?

Ohm's law states: I*E=P in other words: I = amps, P=watts, E=volts If: I or Amps=20 and E or Volts=120 (i am guessing as this one is standard for a residance) Then: 20 * 120 = 2400 or 2400 watts of power are avaliable 2400 watts / 110 watt bulbs = 21.8 bulbs can in theory, be placed on a 20 amp 120 volt circuit. The reality is that you would probably not want to place more than 17 or 18 100w bulbs on a circuit for safety and code required design load calculations. However you can bet that all bulbs in a residance will not be active at one time and therefore seldom will the peak load be at max. None of this takes into account any other loads on the circuit or derating factors such as heat, etc. When in doubt always get a qualified electrician to help or guide you as electrical fires are the cause of much property loss and life safety concern. SAFETY FIRST AND ALWAYS! Hope this helps! Terry


What is the lumen out put per 4 foot fluorescent T-12 light tube?

A typical 4-foot fluorescent T-12 light tube produces around 2,300 to 2,600 lumens of light output.


What is the equivalence of 20 foot candles in watts?

There is no direct equivalence between foot candles and watts as they measure different aspects of light. Foot candles measure illuminance (light intensity on a surface), while watts measure power consumption. The relationship between the two depends on various factors like the efficiency of the light source and the distance from the source to the surface.

Did early florescent bulbs draw little power?

Take a 4 foot tube of 10 years back they used 40 watts today they only use 34 watts, that does not seem like a lot until you have to light a office area or a work area then it adds up on the electric bill. so less is better
