Can You Install Recessed Lights in an Existing Ceiling?
Yes — remodel housing (old work) is designed for finished ceilings. No attic access needed. Spring clips grip drywall from above, and we fish the wiring from the nearest switch or junction box.
How We Install Recessed Lights in a Finished Ceiling
- Locate and cut: We mark joist positions with a stud finder, trace the housing template, and cut the hole — for pre-war Manhattan plaster ceilings, we switch to a carbide-tipped hole saw because drywall saws crack the plaster.
- Fish and connect: We run NM-B 14/2 cable from the switch box to the hole using fish tape or glow rods, then wire-nut connections inside the housing’s integral junction box (black to black, white to white, ground to ground).
- Secure the housing: We squeeze the remodel housing spring clips, push the unit into the hole, and release — the clips grip the drywall from above. No attic or crawlspace required.
- Trim and test: Snap-in baffle trim goes on, we install a BR30 or PAR30 LED bulb (or integrated LED module), then replace the existing switch with an LED-compatible dimmer — standard incandescent dimmers cause flicker with LED bulbs.
- Timing and cost: First fixture runs 30–45 minutes; each additional fixture on the same circuit takes 15–25 minutes. Our recessed lighting installation runs $150–$400 per fixture across all five NYC boroughs.
Slim LED Wafer Lights for Shallow Ceilings
For Manhattan pre-war apartments with less than 4 inches between ceiling and floor above, we install slim LED wafer lights that need only 1/2 inch of clearance — no housing required. Standard 6-inch remodel housings need 7.5 inches of clearance, so wafer lights are the only option for most pre-war shallow ceilings. The fixture clips directly to the drywall, and the integrated LED driver connects to the same 14/2 wiring we fish from the switch. No junction box, no spring clips, no baffle trim — just a 4-inch or 6-inch wafer that sits flush. On an Upper West Side job last month, we swapped a homeowner’s plan from Halo H7RT housings to Lithonia WF6 wafers after we measured the plenum at 3.25 inches. Standard housings wouldn’t have fit, but the wafers went in without a hitch. For shallow ceilings, wafer lights aren’t just easier — they’re the only code-compliant path.
How Many Recessed Lights Do I Need Per Room?
The number depends on room size, ceiling height, and purpose. General rule: 1 light per 4–6 sq ft for ambient lighting, closer spacing for task areas.
Recessed Light Spacing by Room Type
| Room Type | Spacing (8 ft ceiling) | Fixtures per 100 sq ft | Beam Angle |
|---|---|---|---|
| Kitchen (task) | 4 ft | 6–8 | 25°–40° |
| Living room (ambient) | 6 ft | 3–4 | 60°–120° |
| Bedroom | 6–8 ft | 2–3 | 60°–120° |
| Hallway | 4–6 ft along center | 1 per 4–6 ft | 60°–120° |
Formula for Calculating Fixture Count
Divide room length by spacing distance, then room width by spacing distance — multiply the two results for total fixtures. A 12×14 kitchen with 8-foot ceilings and 4-foot spacing gives you 3 lights across and 4 lights long, totaling 12 fixtures. That’s nowhere near the 42 lights a naive “1 per 4 sq ft” blanket rule would suggest, because spacing follows ceiling height, not just square footage. The 4-foot gap between cans is what actually produces even light without dark zones or overlapping hot spots on the countertop.
Are LED Recessed Lights Better Than Halogen?
LED recessed lights outperform halogen in nearly every category — energy use, lifespan, safety, and versatility. Here’s the breakdown.
LED vs Halogen: Side-by-Side Comparison
| Feature | LED | Halogen |
|---|---|---|
| Power (800 lumens) | 12W | 60W |
| Lifespan | 25,000–50,000 hrs | 2,000–4,000 hrs |
| Heat output at trim | None — cool to touch | Hot — fire risk near insulation |
| Color temperature options | 2700K–5000K | ~3000K only |
| CRI (color rendering) | 90+ available | 100 (perfect) |
| Dimmable | Yes — with LED-compatible dimmer | Yes — standard dimmer |
| Upfront cost per bulb | $15–$30 | $5–$10 |
Why We Recommend LED for NYC Homes
We install LED recessed lights in NYC homes because they run cool enough for insulated ceilings and last decades — no bulb changes in hard-to-reach vaulted ceilings. A 12W LED delivers the same 800 lumens a 60W halogen does, which means 80% less energy draw per fixture. That 25,000–50,000-hour lifespan translates to 20–40 years of typical use before replacement. In Brooklyn brownstones with knob-and-tube wiring, LED’s low wattage reduces load on aging circuits — a safety advantage halogen can’t match.
What Is the Best Recessed Lighting for Kitchens?
Kitchen lighting needs two layers — task lighting over counters and islands, and ambient lighting for the whole room. Here’s what works best.
Task vs Ambient: Choosing the Right Fixtures
- Task areas (counters, island, sink): We install 4-inch or 6-inch LED fixtures with narrow 25°–40° beam angles spaced 4 feet apart, placed 12–18 inches from cabinet faces so your body doesn’t cast shadows during prep work.
- General ambient: 6-inch LED fixtures with wider 60°–120° beams at 4–6 foot spacing — this evens out the light across the whole room without hot spots.
- Color temperature: 3000K–3500K range (soft white to neutral white) — the sweet spot for food prep because it doesn’t distort how meat doneness or vegetable freshness looks under the light.
- CRI: 90+ minimum — below that, raw chicken and ripe tomatoes start looking the same shade, which is a safety issue you don’t think about until it happens.
- Dimmer: Required — we pair these with a Lutron Diva or Leviton Decora LED-compatible dimmer; standard incandescent dimmers cause flicker and shorten LED lifespan.
- IC-rated: Required if insulation sits above the ceiling — common in top-floor NYC apartments — because non-IC housing near insulation creates a fire risk and nuisance tripping of the thermal protector.
- Air-tight: Required by NYC energy code — prevents conditioned air from leaking into the ceiling plenum, which in a pre-war building can add noticeable draft and raise heating bills.
Recommended Brands for NYC Kitchen Installations
For NYC kitchens, we typically install Halo H7RT remodel housings for standard ceilings or Lithonia WF6 slim LED wafers for shallow pre-war plenums — both IC-rated and air-tight. The Halo runs about $25–$40 per housing at standard electrical supply houses across the five boroughs, while the Lithonia wafer runs $15–$25 and needs only half an inch of clearance. In Brooklyn brownstone kitchens with plaster ceilings, DMF DRD fire-rated housings are worth the $15–$30 premium because they maintain the floor-ceiling fire rating if the kitchen sits above a basement — and the intumescent material inside expands in a fire to seal the hole, which a standard housing won’t do.
Can Recessed Lights Be Installed Between Floors?
Yes — but NYC Electrical Code requires fire-rated housing to maintain the floor-ceiling fire rating. Standard non-fire-rated housing between floors is a code violation.
Fire-Rated Housing Requirements in NYC
We install fire-rated housings like DMF DRD or Halo H7RICT between floors — they contain intumescent material that expands in a fire to seal the hole and maintain the assembly’s fire rating. The housing must be UL-classified for the specific fire-resistant floor-ceiling assembly type; no additional fire caulking is needed if the housing carries that rating. These units cost a $15–$30 premium over standard remodel housings, but the 2025 NYC Electrical Code makes them mandatory for any penetration through a floor-ceiling assembly. That code went into effect December 21, 2025. Slim LED wafer lights are NOT fire-rated — using them between floors in NYC violates the code and could invalidate your building’s fire insurance.
Wiring Access for Between-Floor Installations
- Attic or crawl space above: Drop NM-B 14/2 or 12/2 cable down through the joist bay — 15–30 min per run
- No access above: Fish wire from the switch box or nearest junction box — same process as a standard remodel install
- Air-tight housing: Required by NYC energy code — gaskets seal against drywall to prevent conditioned air from leaking between floors
- IC-rated: Required if insulation is present between floors, which is common in newer buildings
Can You Install Recessed Lights in a Sloped Ceiling?
Yes — but standard baffle trim points light straight down, which on a slope sends light at an angle. Gimbal trim or sloped-ceiling adapters fix this.
Gimbal Trim vs Sloped-Ceiling Adapter
| Solution | Max Slope | Adjustment | Aesthetic | Added Cost |
|---|---|---|---|---|
| Gimbal trim | 30°–45° | 30°–45° adjustable | Visible ring | $10–$25 |
| Sloped-ceiling adapter | 30° (housing limit) | Housing mounted at angle | Flush (no visible ring) | $15–$30 |
| Slim LED wafer with gimbal | 35° | Built-in adjustable | Low-profile | $0–$10 over standard wafer |
Common Sloped Ceiling Locations in NYC
We install sloped-ceiling recessed lights in Brooklyn brownstone stairwells, Queens and Staten Island vaulted living rooms, and Manhattan pre-war dormer bedrooms. A gimbal trim from Halo or Junta rotates 30°–45° to aim light straight down regardless of pitch — on a Brooklyn brownstone dormer with a 35° slope, that makes the difference between a usable reading nook and a wall-wash. Wiring a sloped ceiling is the same as a flat ceiling — but the junction box must remain accessible, so we use housings with integral boxes accessible through the trim opening. For steep slopes over 30°, a sloped-ceiling adapter like the Halo S700 mounts the housing at the correct angle, which gives a flush look — some homeowners in Carroll Gardens prefer that over the visible gimbal ring.

Final Thoughts on Recessed Lighting in NYC
Main Takeaways
Recessed lighting installation in NYC requires careful planning — from choosing the right housing type to complying with the NYC Electrical Code. Remodel housing works for existing ceilings; slim LED wafer lights solve shallow plenum problems. Fire-rated housing is mandatory between floors — no exceptions. LED outperforms halogen in energy, lifespan, and safety for every application. Kitchen lighting needs task and ambient layers with appropriate beam angles and spacing. Sloped ceilings need gimbal trim for proper light direction. A 1-year warranty on parts and labor is the NYC standard for professional electrical work. The biggest mistakes homeowners make are using non-IC housing near insulation, installing non-fire-rated fixtures between floors, and pairing LED lights with standard dimmers — all avoidable with a licensed electrician.
