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 15,840 lm fixture and 33 smaller ones add up the same but look completely different.

Where 15,840 lumens comes from

Lighting is specified in foot-candles — lumens landing on each square foot of the surface you care about. A basement is worked to 30 foot-candles. Across 528 ft² that is 15,840 lumens in total.

Split it up

One fixture putting out 15,840 lumens and 33 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.

Color temperature

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