Where 16,800 lumens comes from

Lighting is specified in foot-candles — lumens landing on each square foot of the surface you care about. A garage is worked to 50 foot-candles. Across 336 ft² that is 16,800 lumens in total.

Split it up

One fixture putting out 16,800 lumens and 21 fixtures adding up to the same number light a room very differently. A single source throws hard shadows and glare; several spread the light and make the room feel larger. Aim for layers — ambient, task, and something low for the evening.

Colour temperature

4000–5000K suits this room. Warmer light reads as relaxed and is what you want where people wind down; cooler light keeps edges and colours crisp, which matters where there is work to do.

Notes

  • Foot-candles are lumens per square foot at the work surface. Ceilings above 9 ft, dark walls or dark flooring all eat light — add roughly 10% per extra foot of ceiling height.
  • Spread the total across several fixtures rather than one bright source. One 16,800 lm fixture and 21 smaller ones add up the same but look completely different.
