There are great differences in FC/watt or CP/watt, depending on fixture type. Doesn't this affect the results?cschmid said:the simplest way to measure your LPD is to multiply your LPD by the square footage this establishes the maximum allowable wattage for that space..So you can calculate each space differently..
If you are classified an automotive repair shop you LPD should be about 1.5 per square ft..If you were classified as a manufacturing facility it would be 2.2 per square ft..
I only mention this because the square footage you are probably doing is worth while if you reduce your general lighting by 25 percent you get.30 per square ft the price goes up for every percentage reduced..Just a thought that might be worth while..
