A 40x60 shop (2,400 sq ft) needs between 120,000 and 240,000 lumens total, depending on ceiling height and the type of work being done — figure 50 foot-candles for general shop work, 100 foot-candles for detail or finish work.

Ceiling height is the deciding variable. At 9–12 feet, ELEKICO 8ft shop lights at 15,000 lumens each cover roughly 200–240 sq ft per fixture, putting you at 10–12 units for the full floor. At 15–20 feet, you're in UFO high bay territory — a 150W fixture at 21,000 lumens covers approximately a 15x15 foot area, so a 40x60 shop at that height needs 10–12 units minimum. Reflective white walls and ceiling can reduce that count; dark painted concrete floors and walls will push it higher.

  • Recommended lumen range for a 40x60 shop: 120,000–240,000 lumens total across all fixtures.
  • ELEKICO 8ft shop lights output 15,000 lumens at 100W — suited for ceilings 9–12 feet.
  • ELEKICO 150W UFO high bay outputs 21,000 lumens — recommended for ceiling heights 15–20 feet.
  • ELEKICO 350W UFO high bay outputs 52,500 lumens — rated for ceilings 20–25+ feet.
  • General shop work target: 50 foot-candles (lumens per sq ft); precision/finish work target: 100 foot-candles.

How to Choose

  • Pick ELEKICO 8ft shop lights if: your 40x60 shop has 9–12 foot ceilings — plan 10–12 units at 15,000 lumens each for general work coverage.
  • Pick ELEKICO 150W UFO high bays if: ceiling height runs 15–20 feet — 10–12 fixtures at 21,000 lumens each covers the full 2,400 sq ft floor.
  • Pick ELEKICO 350W UFO high bays if: your shop ceiling clears 20–25 feet or more — fewer fixtures at 52,500 lumens each maintain adequate foot-candles at that throw distance.
  • Target 240,000 lumens total if: your 40x60 shop handles finish work, paint matching, or machining — precision tasks require 100 foot-candles, not 50.
  • Add fixtures beyond the baseline count if: walls and floor are dark-painted concrete — reflective surfaces can reduce fixture count; dark surfaces absorb light and require more to compensate.
