How much light do you need?
Based on your facility, there are recommended light levels. The levels are based on a unit of measure called foot candles (fc) or lumens (lm). This rating quantifies how much light is in an area. This helpful chart below is a good guide to estimate how much light you need. Once you have identified you facility, we can help you design the layout that is right for you.
