Pot Lights and Lighting Installation in Cambridge
Lighting is the upgrade owners can see every evening, which is why it gets done badly in a hurry. In a Galt stone house with ten-foot plaster ceilings and a crown moulding, the choice of fixture matters as much as the wiring behind it.
Lighting requests come from every part of Cambridge, and the ceiling decides the job. A Preston Heights side-split with a single fixture per room and an accessible attic is the easy case. A Hespeler mill worker's cottage with low ceilings and shallow joist bays needs slim fixtures and a careful layout. A Dickson Hill stone house with original plaster medallions and deep cornices is a place where pot lights may be the wrong answer altogether, and a good contractor will say so and offer picture lights, sconces or a well-placed pendant instead.
The layout is done in the room
A recessed lighting layout is not a grid on a drawing. It depends on the height of the ceiling, where the counters, seating and artwork actually are, what the room is used for, and what is above the ceiling — joists, ducts, plumbing, and in older houses the old wiring. Kitchens want light on the work surfaces and inside the task zones, not down the middle of the floor. Living rooms want the walls washed and the seating lit, with the centre of the room softer. Halls and stairs want even, safe light on a switch at each end. The contractor walks the room with you, marks the ceiling, then checks what is above each mark before anything is cut.
Drywall ceilings with an attic above
The most common case in the post-war and newer streets. Thin LED fixtures rated for contact with insulation go in from below, cable is run across the attic, and a dimmer at the wall controls the run. The care points are the insulation and the vapour barrier: fixtures must be rated for insulation contact, and any barrier disturbed is sealed. Where the attic is deep in blown-in insulation, the contractor works from below rather than wading through it.
Ceilings with a floor above
A main-floor ceiling in a two-storey house has no attic, so cable is fished between joists from the nearest opening, and the run of the joists, the ducts and the plumbing decide where fixtures can go. The layout is adjusted to that rather than forced through it. Occasionally one small access hole is needed, and it is patched.
Plaster, stone and heritage houses
Galt, Preston, Hespeler and Blair have ceilings of plaster on wood lath, sometimes with a medallion, a cornice or a painted border worth keeping. Cutting recessed fixtures into plaster takes the right hole saw and a steady hand, and if the ceiling carries live knob-and-tube the new lighting goes on a new circuit and the old wiring is dealt with, not spliced into. In many of these rooms the better choice is surface-mounted or suspended lighting that respects the ceiling, and the contractor will help you make that call rather than sell a dozen holes. For exterior fixtures on a designated property in one of the city's heritage conservation districts, the city's heritage staff may want to see what is proposed on a visible elevation; interior wiring is ESA's domain as in any other house.
Kitchens, bathrooms and the outside
- Under-cabinet lighting. Hardwired LED strip or pucks, switched at the wall, placed so the source is hidden from standing height.
- Bathrooms. Wet-rated fixtures over the shower, proper light at the mirror, and a fan on its own switch or timer.
- Exterior and landscape. Porch, garage, driveway and soffit lighting, path and garden lighting, and on rural properties yard lights and a lit route from the house to the shop, all on proper outdoor circuits with weatherproof boxes.
- Dimmers and controls. Matched to the LED fixtures so they do not flicker or buzz, which is the most common complaint after lighting work done with the wrong dimmer.
- Ceiling fans. Boxes rated for the weight and movement of a fan, not a standard fixture box.
When ESA is involved
Replacing a fixture like for like on its existing box generally does not need a notification. Adding fixtures, running new cable or adding a circuit generally does, and the contractor files it with the Electrical Safety Authority as part of the work and tells you which applies before starting.
Frequently asked questions
How many pot lights does my room need?
It depends on ceiling height, what the room is for and where the light needs to land, not on square footage alone. The layout is worked out in the room with you, then checked against the joists and ducts above, and only then quoted.
Are pot lights a good idea in a century home?
Sometimes, and sometimes not. In a plain plaster ceiling they can be cut cleanly and fished from above. In a room with a medallion, cornices or original features, surface or suspended fixtures usually suit the house better and the contractor will say so rather than sell holes.
Why do my LED lights flicker when dimmed?
Almost always the dimmer: an older incandescent-rated dimmer on LED fixtures. Matching dimmer to fixture is part of every lighting job here, and correcting someone else's mismatch is a short visit.
