How far apart should recessed lights be spaced?
Recessed lights are commonly spaced about as far apart as half the ceiling height to the full ceiling height, and kept a similar distance from the walls. Closer spacing gives brighter, more even light. The right layout depends on the room, the beam angle of the fixtures and what the room is used for.
Kitchens and work areas usually need tighter spacing than hallways or bedrooms. A drawn plan on paper, with each light marked, saves a lot of trouble before any hole is cut. Joists, ducts and wiring above the ceiling can force changes to the layout.
It helps to think in zones. Put task lighting over counters and a separate switch or dimmer for general lighting, so the room can change with the time of day.
What type of recessed light housing do I need?
The housing you need depends on your ceiling. New construction housings mount to joists before the ceiling is finished, while remodel housings clip into an existing ceiling hole. If the housing touches attic insulation, it must be rated for insulation contact, and a damp location rating may be needed in some spaces.
In Arizona attics, temperatures run well above 110 degrees in summer, which is hard on wiring and on lights that are not rated for the conditions. Using the correct housing helps prevent overheating and keeps insulation from covering parts that need to shed heat.
LED retrofit units, sometimes called wafer lights, are thin and need less depth above the ceiling. They are often chosen for homes with tight attic space, though they still need proper wiring and a compatible dimmer.
Do recessed lights need a new circuit or a permit?
Recessed lights often connect to an existing lighting circuit if it has spare capacity, but a large number of fixtures or a new switch location may need additional wiring. Some projects need a permit and inspection. A licensed electrician can check the circuit load and tell you what applies in your city or county.
LED fixtures draw little power, so capacity is less of a problem than it was with older bulbs. The more common issue is the condition of the existing wire and boxes, especially in older homes in Sun City and parts of Glendale where original wiring may be present.
Adding fixtures to a circuit that already feeds outlets, or splicing in the attic without a proper junction box, creates hazards. Each splice belongs inside an accessible box.
What can a homeowner safely do with recessed lights?
A homeowner can safely plan the layout, pick fixtures, and replace a bulb or trim in an existing can with the switch off. The cable runs, switch wiring, and any work in the panel or attic splices should be left to a licensed electrician, since mistakes can hide inside a ceiling.
If a recessed light flickers, buzzes, or the trim feels hot, turn it off and have it looked at. A burning smell, scorched trim, or tripping breaker means stop using that circuit and call for service.
For projects that add many lights or a new switch, Vortech can handle licensed electrical work and the lighting upgrades together, so the ceiling is opened once.
