To calculate the load in amps for the circuit, first determine the total wattage of the fixtures. The four 150W incandescent fixtures contribute 600W (4 x 150W), and the six fluorescent fixtures (assuming a typical wattage of 32W each) contribute 192W (6 x 32W). Adding these together gives a total of 792W. Using the formula ( \text{Amps} = \frac{\text{Watts}}{\text{Volts}} ), the load in amps is ( \frac{792W}{120V} = 6.6A ).

Why do most schools use fluorescent strip lighting?
Fluorescent strip lighting is commonly used in schools due to its energy efficiency, bright and uniform light output, and low operating cost. Additionally, fluorescent lighting is long-lasting and provides a suitable level of illumination for classrooms and other educational spaces.
How much electricity needed for 100 watt compact fluorescent lamp?
The answer is simply100 Watts. The Wattage rating of electric light bulbs is just the amount of electricity they consume. So a 60 Watt bulb would take 60 Watts of electricity. In fact, if you could buy a 100 Watt CFL, it would have the light output equivalent to about eight 100 Watt conventional (incandescent) light bulbs.
How many volts needed to run a fluorescent light?
The voltage of your area is what determines the operating voltage of all equipment. Equipment from other countries usually has to use a transformer to get the correct voltage. The voltage on a fluorescent fixture is printed on the ballast of the fixture. See if the voltage on the ballast matches the supply voltage of the system that you are going to use to operate the fixture.
If you operate an incandescent light bulb at less than its rated voltage?
Since an incandescent light bulb is an appliance that has a fixed electrical resistance, operating it at less than its rated voltage means that it will draw less than its rated current and will produce less light.
How long will T5 lights last?
T5 bulbs technically will last for about 20 000 hours. That's over 2 years if they were on continuously. However, if you are using them for an aquarium, they should be replaced every 10-12 months.
About how much money does a consumer save over three years by using a fluorescent bulb in place of an incandescent bulb?
The latest comparisons for energy efficiency and energy costs based on a 1200 hour incandescent lamp at 60 watts are;Light Emitting Diodes (LED) - 329 kWh/year at an operating cost of $32.85 per year.Incandescent Light Bulbs - 3285 kWh/year at an operating cost of $328.59 per year.Compact Fluorescents (CFLs) - 767 kWh/year at an operating cost of $76.65 per year.

The current drawn by a 250-watt incandescent lamp operating at 120 volts is?
P = i*v250w = i * 250vi = 250/120 = 2.08a
How long do fluorescent lights last and what factors can affect their lifespan?
Fluorescent lights typically last around 10,000 to 15,000 hours. Factors that can affect their lifespan include the frequency of turning them on and off, the quality of the ballast, and the operating temperature.
Why do most schools use fluorescent strip lighting?
Fluorescent strip lighting is commonly used in schools due to its energy efficiency, bright and uniform light output, and low operating cost. Additionally, fluorescent lighting is long-lasting and provides a suitable level of illumination for classrooms and other educational spaces.
What determines the operating voltage of an incandescent globe?
The length ,thickness, and alloy of the filament determines its resistance. The lower the resistance, the lower the voltage required to power it.
Which type of energy other than light energy is produced by incanduscent lights?
Incandescent lights produce heat energy in addition to light energy. This heat energy is a byproduct of the light-producing process and is why incandescent lights can become hot to the touch when operating.

Who made incandescent light bulb?
Thomas Edison made the first operating incandescent light bulb. But in 1800, Humphrey Davy invented the electric light. It didn't last long, and was not a bulb, though. Arc lights later became popular, but again, were not in a bulb.
