Garage Lighting Layout Guide

Step 1: the total, from floor area

Everything starts here, and it is one multiplication. A working garage wants 50-75 lumens per square foot — call it 60 for a sensible middle.

Under-buying is the universal error here. A single 4,400 lumen fixture in the middle of a two-car garage is about 16% of what the room needs, and it is what most garages have. If the garage feels dark with the lights on, this is almost always why.

Step 2: placement, which matters as much as quantity

Two fixtures in the right places beat three in the wrong ones. The rule is counter-intuitive: do not center the lights over the car.

A fixture directly above a car lights its roof, and the roof is the one part of a car you do not work on. The sides, the wheels, the engine bay and the walls behind are all in shadow — the car blocks the light.

So: run fixtures in rows along the length of the bay, positioned over the sides of where the car sits. For a two-car garage, that is typically two rows of two fixtures each, with the rows roughly 2-3 feet in from each side wall and one down the middle between the bays if the garage is wide.

• 2-3 ft from the side walls, so the light reaches your wall storage. A fixture tight against a wall lights the wall and nothing else; a fixture too far out leaves the wall dark.
• Along the length, not across, so you get continuous light down the bay rather than bright bands and dark gaps.
• Avoid the door track and the opener. Measure the clear ceiling run before you commit to 8 ft fixtures, which frequently do not fit where you wanted them.

Step 3: the fixture geometry changes the spacing

A flat LED panel throws light straight down, so it produces a bright stripe directly beneath and darker gaps between fixtures. Spacing has to be tighter.

ELEKICO's V-shape gives 270 degrees of spread, throwing light sideways at the walls as well as down. That means wider spacing covers the same area usefully, and — more importantly in a garage — the light reaches the pegboard, the shelving and the labels on the bins.

Practical consequence: with a V-shape or similarly wide-distribution fixture you can space further apart and get more light on the walls. With flat panels, space tighter and accept that the walls get less.

Step 4: the bench needs its own light

This is the thing more ceiling light cannot fix, and it is worth understanding why.

You stand at a bench leaning over your work. The light is above and behind you. Your head and shoulders block it, so the thing you are looking at is in your own shadow — and making the ceiling light twice as bright makes your shadow twice as sharp, not less dark.

The fix is light from a different angle, close to the work:

• A slim T5 strip mounted under a shelf directly above the bench. Barrina's 2,200 lm T5 is ideal — slim enough to fit under a shelf, links up to 8, and costs very little. This is the single best lighting purchase in a garage after the ceiling fixtures.
• A bench with an integrated magnetic LED strip. Eltean, Rumetol, HAK and CAMMOO all ship one, and the magnetic mount means you reposition it to kill the shadow rather than working around it. See the best garage workbenches.
• A portable work light for anything inside a cavity. See the best garage work lights.

Step 5: check the electrical plan

Linkable fixtures share a plug, so two numbers matter: the maker's link limit, and the total watts on that chain.

Six hykolity fixtures at 42W is 252W on one plug, which is comfortable. Three SHOPLED 8-footers at 100W is 300W, which is where you check the cord rating and consider a second circuit. Full table on 4 ft vs 8 ft shop lights.

Also think about switching. A single switch for everything is simplest; separate switching for the bench light is better, because you often want task light without lighting the whole garage. Several fixtures here have a switch on the cord or a pull chain (Sunco), which gives you that for free.

The free upgrade: paint

A dark garage ceiling absorbs the light you just paid for. White paint reflects it back into the room, fills shadows and makes the same fixtures measurably more effective.

Light-colored walls do the same, and in a garage they have a second benefit: you can see what is on the shelves. A tin of white ceiling paint is the cheapest lighting purchase available and it is usually the last thing anybody considers.

A worked 2-car layout

1. Four 4 ft fixtures at 7,500 lm, in two rows of two running the length of the bay, each row 2-3 ft in from a side wall. Total 30,000 lm.
2. One T5 strip under the shelf above the bench, on its own switch.
3. One portable work light in the tool chest for cavities.
4. White ceiling.

That is six mounting points, two cord runs, two switches, and a garage you can actually see in.
