LED High Bay Calculator: how many fixtures and what spacing

Enter the floor size, the mounting height and the lumens of one high bay (from its product page). The calculation follows general industry guidelines (IES): lumens per square foot by use, spacing of about 1 to 1.5 times the mounting height.

Floor area– sq ft
Target lumens– lm
Recommended high bays–
Maximum spacing– ft
Distance from walls– ft
Suggested layout–rows × columns

Rules of thumb for an open floor; racking, aisle height and dimming change the result. For a project, ask us for a quote with your drawings.
