How many can lights do you need? A no-nonsense layout guide
Too few and the room looks like a cave. Too many and it looks like an airport. Here is the spacing rule we use, and the dimmer mistake behind most flicker.

Recessed lighting is the highest-impact upgrade per dollar in most rooms. It is also the easiest one to get wrong, because once the holes are cut, they are cut.
The spacing rule
A good starting point: space cans about half the ceiling height apart. An 8-foot ceiling means roughly 4 feet between lights, and about 2 feet in from the walls. Then adjust for what the room is for.
Kitchens: light the counters, not the middle of the floor
Living rooms: fewer, dimmable, and away from the TV wall
Bathrooms: one over the shower and one in front of the mirror
Why LEDs flicker
Almost always a dimmer that does not match the LED driver. It is a cheap fix — and the reason we pick the dimmer before we pick the lights.
FROM THE TRUCK
We mark every can on the ceiling in pencil and walk it with you before anything gets cut. If the layout looks wrong in pencil, it will look wrong forever.
LED LIGHTING INSTALLATION
From $180 per fixture
Per-light pricing drops fast with quantity. Twelve cans in one visit cost far less per light than one added later.
