Canless Recessed Lighting from NuWatt
What Is Canless Recessed Lighting?
Canless recessed lighting refers to LED downlights that do not require metal housing, otherwise known as cans, above the ceiling. Each fixture combines an integrated LED light with its own compact junction box, while our strong spring clips lock it flush to the drywall. No can, no bulky hardware, easy installation.
Many of these fixtures are considered "ultra thin recessed lighting" because they need as little as 2 inches of clearance and can come in direct contact with any insulation. This wafer style build is also sold as "canless wafer lights".
Beyond wafers, NuWatt canless lights come in five sizes (1, 2, 3, 4, and 6 inch), including anti-glare, trimless, and adjustable gimbal fixtures built with powerful COB LED chips with IC-rated heat sinks for high output installs.
Canless vs. Traditional Can Lights
Traditional cans need a metal housing mounted to framing; canless skips the housing entirely.
| Canless recessed lights | Traditional can lights | |
|---|---|---|
| Housing | No housing, just integrated LED + junction box | Metal can required |
| Clearance needed | As little as 2" | 6" or more |
| Install | Cut hole, wire J-box, snap in | Open frame, mount can to framing, add recessed light |
| Joist in the way? | Shift the hole and keep going | Reroute around framing |
| Best for | Remodels, low ceilings, new layouts | Open ceilings in new construction |
Canless Recessed Light Sizes: 1", 2", 3", 4", 6"
NuWatt canless lights come in five sizes. Pick based on the room and the job:
- 1 to 3 inch: accent lighting for hallways, niches, artwork, and architectural detail. Small aperture, minimal ceiling presence.
- 4 inch: the all-rounder. 4 inch canless recessed lighting fits kitchens, bedrooms, bathrooms, and hallways.
- 6 inch: maximum coverage. 6 canless recessed lighting suits living rooms, basements, and open floor plans.
On 8-foot ceilings, space 4 inch lights 4 to 5 feet apart and 6 inch lights 5 to 6 feet apart, with the first row 2 to 3 feet off the walls. Put every room on a dimmer.
Trim Styles for Canless Lights
Every style below is built for canless installation, no housing or adapter needed:
- Anti-glare: regressed COB light source with a deep lens cuts harsh reflections for comfortable, glare free light.
- Trimless: muds into drywall for a flush finish with no visible trim ring.
- Gimbal trim: tilting head washes walls or spotlights art, ideal for sloped ceilings.
- Square trim: a geometric alternative to round for modern interiors.
- Black trim: low-contrast architectural finish.
- Baffle trim: ribbed interior softens glare for living rooms and bedrooms.
- Smooth trim: clean reflector for maximum output.
How to Install Canless Recessed Lighting
Canless recessed lighting installation is a manageable DIY project. Check local code first, since many areas require a licensed electrician. Cut a round hole with a hole saw, wire the included IC-rated junction box, push it into the ceiling cavity, then plug in the fixture and push it up until the spring clips lock it flush.
Are canless LED lights dimmable?
Yes, NuWatt canless LED lights dim smoothly to 10% on an LED-rated dimmer, and the built-in 5CCT switch dials color temperature from 2700K to 5000K.
