Before Adding Recessed Lights
A great recessed lighting install is 70% layout, 20% fixture choice, and 10% installation. Most homeowners flip those numbers and end up with rooms that feel like a dentist’s office. This guide fixes that.
01
Who this is for
- Homeowners renovating a kitchen, living room, basement, or bedroom
- Anyone planning to replace existing flush-mount fixtures with cleaner recessed
- Long Island homeowners with attic access asking ‘how many should I add?’
02
What you should know first
Spacing basics
Rule of thumb: spacing between lights should be roughly the fixture diameter × 6 inches. For a 4-inch light, that’s about 24 inches apart. For a 6-inch light, ~36 inches. And keep them 18–24 inches off walls to avoid harsh shadows.
Wafer (canless) vs can lights
Wafer/canless lights are slim, fast to install, and great where joist space is tight. Traditional can lights are deeper, fit specific trim styles, and let you swap bulbs. For most modern installs, wafers are the right call.
Color temperature
2700K = warm (like incandescent). 3000K = warm-neutral. 3500K = neutral. 4000K = cool. For homes, 2700K or 3000K. Never mix temperatures across one room — your eye reads it as ‘something’s off’ even if you can’t name it.
Dimmer compatibility
Not every dimmer works with every LED. Mismatched dimmers cause flicker, buzz, or limited dimming range. Confirm the fixture brand + dimmer brand are on each other’s compatibility list before buying.
Attic access vs no attic access
With attic access, fixture install is fast and clean. Without (e.g., a second-floor ceiling under a finished space), we ‘old-work’ from below — totally doable but slower and more careful.
Room size affects layout
Small bedrooms often need just 4 lights; a large open kitchen/living can need 12–16. The right number is whatever evenly lights the room without creating bright spots and dark corners.
03
Common mistakes to avoid
The patterns we fix most often. Skip these and you’re ahead of most homeowners.
- Eyeballing the layout instead of measuring and drawing it
- Mixing color temperatures across a room (or even a floor)
- Buying fixtures and dimmer separately without checking compatibility
- Putting recessed lights too close to walls (creates shadows)
- Using one zone for the whole room — kitchens and basements need 2–3 zones
- Skipping dimmers entirely — instantly makes the room feel sterile
04
What affects cost
- Fixture count and quality
- Attic access (yes = faster) vs old-work cuts from below
- Number of switching zones / 3-way switches
- Whether new circuits or just extending existing
- Patch and paint expectations
- Dimmer type (smart dimmers cost more)
05
What the process usually looks like
- 01Walkthrough + layout sketch (in person or from your photos)
- 02Confirm fixture, color temp, and dimmer choices
- 03Permit pulled if your town requires it
- 04Install day: cuts, wiring, fixtures, switches, dimmers, test
- 05Demo the dimming + color with you before we leave
Quick self-check
Is this project right for you?
Three quick yes/no questions. Answer honestly — you’ll get a straight read in under a minute.
1. Do you have attic or crawl space access above the room?
2. Have you decided on color temperature (2700K or 3000K)?
3. Are you OK with at least 2 dimming zones for a larger room?
