Installing Shop Lights
January 07, 2011
I have been involved with Cypress’s lighting products pretty much from the beginning, but there is nothing better than actually doing our own lighting project. My new shop is 20’ by 23’ and I wanted at least 75 foot-candles (fc) of light. I went to this really cool website ( www.cooperlighting.com/iesCalculator/FlashIndoor.cfm?fp=/specfiles/ies/Metalux/SURFACE/WB/&fn=WB-432A.ies) and they recommended six, four 48” bulb fluorescent fixtures. Given normal wall, ceil and floor reflectance I have about 95 fc. I just had the floor epoxy coated and I am well over 100 fc. You don’t really get a feel for lumens, foot candles and such until you actually do a design, One thing I learned is with 24 bulbs, LEDs will have to get a heck of a lot cheaper before I could afford them. My cost including wire, conduit, fixtures and bulbs was about $500 for 67,200 lumens or about 3/4s of a penny per lumen.
