I currently have 51 T12 48" 2 lamp shop lights in my shop.
I am looking into changing to some more energy efficient lighting.
I read that T8 & T5 lights are more energy efficient than the T12s. I am confused on how they are more energy efficient when they use the same wattage bulbs.
I was taught that wattage is energy used, so how does the same wattage use less energy?
The current shop lights are plugged into outlets in the ceiling. I am also toying with the idea of getting plug in light socket adapters & LED flood light bulbs to plug into the outlets to see how they would light the shop. What I like about this idea is that it would cost less for the conversion & some of the LED bulbs have the color of incandescent bulbs.
The ceiling in most of the shop is 9' 6". another part has a cathedral ceiling that starts at 9' 6" & goes up to 12'.
I did a calculation of energy use if I was to go with all LED bulbs. That would cut my electric bill by about $87 a month.
I have no idea how to figure what the energy cost difference would be to convert to T8 or T5 lights.
