Parking Lot lights -Finding lm/ft2

[AC\DC]

Was asked to Install some Pole mounted parking lot lights. Looking at my city rules I need to keep 2Fc around the entire lot. Maximum of 5Fc above walk ways and Parking lot lights.

I never have done this and every thing I am finding online is not to technical. Parking lot is not a perfect square, lots of little off shoots.
Any one have a handy calculator for this? Or am supplier they know that will design it for you if you use their product?

Ask the lighting rep for the mfg, or the supplier may have some one in house that can do the calcs

Thanks I’ll, try them tomorrow, seems to be something I can’t just do quickly looks very intensive to do it properly.

They will use a lighting program and if you can get them an Autcad dwg with pole locations, heights, and then the luminaire make/model
