Where 6,400 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 128 ft² that is 6,400 lumens in total.
Split it up
One fixture putting out 6,400 lumens and 8 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 6,400 lm fixture and 8 smaller ones add up the same but look completely different.
