How many pot lights do I need for a finished basement rec room in New Brunswick?

The general rule is one 4-inch pot light for every 16 to 20 square feet of basement space, or one 6-inch pot light for every 24 to 36 square feet. For a typical 600 square foot basement rec room in a New Brunswick home, you're looking at 10 to 14 four-inch LED pot lights or 8 to 10 six-inch LED pot lights for even, comfortable lighting.

Basement lighting needs are different from above-grade rooms because basements have no natural light. You need to compensate for the lack of windows with more fixtures and higher total lumens than you'd use in a living room or bedroom upstairs.

Calculating the right number for your space. Start with the room dimensions. Multiply length by width to get square footage. For a basement rec room, you want about 20 to 30 lumens per square foot. A typical LED pot light produces 600 to 900 lumens. So for a 600 square foot room at 25 lumens per square foot, you need 15,000 total lumens. Divided by 750 lumens per fixture, that's 20 lights — but that assumes evenly distributed general lighting. In practice, you can reduce this to 10 to 14 by spacing them strategically and supplementing with task lighting in specific areas.

Spacing and layout matter as much as quantity. Place pot lights in a grid pattern with 4 to 6 feet between fixtures and 2 to 3 feet from walls. Avoid placing lights directly above where a TV will be mounted — the glare is distracting. Put pot lights on separate circuits or dimmer zones so you can control the lighting for movies, games, or general use. A row of pot lights over a bar area or pool table can be on its own switch.

LED pot lights are the only sensible choice for New Brunswick basements. Older incandescent pot lights generate significant heat, which is a concern with insulation contact in ceiling cavities. LED pot lights run cool, use 75 percent less energy, and last 25,000 to 50,000 hours. For basement installations, use IC-rated (insulation contact) LED pot lights that are safe to install in insulated ceilings. Most modern LED pot lights are IC-rated by default, but verify before purchasing.

New Brunswick code requirements for basement lighting. Your finished basement needs AFCI-protected circuits for all living areas (rec rooms, bedrooms) under the current CEC. Bathroom lighting requires a separate GFCI-protected circuit. Stairway lighting must have 3-way switches at both the top and bottom of the stairs. And all pot lights must be properly rated for the type of ceiling they're installed in — IC-rated for insulated ceilings, which is nearly always the case in New Brunswick basements where you're insulating between the basement ceiling joists.

Cost for basement pot light installation in New Brunswick. Each LED pot light costs $20 to $50 for the fixture, plus $100 to $175 for installation including wiring. For 12 pot lights with dimmer switches on two circuits, expect to pay $1,800 to $3,000 total. Add a TSANB permit ($150 to $250) since you're running new circuits. Many electricians offer package pricing for basement lighting that brings the per-light cost down.
