4 in Ultra-Thin LED Recessed Lighting 5CCT 12 Pack - Slim Canless

Our review of the NUWATT 4 in Ultra-Thin LED recessed lights finds them best for homeowners, contractors, and remodelers who need bright, flexible lighting in shallow ceilings. The single biggest reason to buy is the combination of five selectable color temperatures and a thin, canless design that installs in less than 2 in of clearance, delivering versatile illumination without bulky housings. Installation is straightforward thanks to the spring clips and built-in junction box, while CRI90 color accuracy keeps colors natural in living spaces and task areas.

Key Features

• 5 CCT selectable: Choose from 2700K to 5000K to match room mood and task needs without buying multiple fixtures.
• Ultra-thin canless design: Fits in shallow ceilings and renovation sites, eliminating the need for a recessed can and saving installation time.
• Dimmable 10-100%: Works with standard dimmer switches to set precise ambiance and reduce energy use during low-demand periods.
• CRI 90 accuracy: Renders colors more naturally than CRI80 fixtures, useful for makeup, crafts, or retail displays.
• IC rated and airtight: Safe for direct contact with insulation, helps maintain HVAC efficiency and meets code requirements for insulated spaces.
• Damp rated and weather resistant: Suitable for bathrooms, laundry rooms, and covered outdoor soffits where humidity is present.

Who It's For

These slim LED wafers suit homeowners renovating kitchens, bathrooms, basements, or drop ceilings where clearance is limited and professional-looking light is required. Contractors and electricians will appreciate the built-in junction box, snap-in clips, and durable aluminum heat sink that speed up installs on multiple jobs.

Those who need integrated smart control or extremely high lumen output for warehouse-scale spaces should look elsewhere; this product is optimized for residential and commercial rooms that need efficient, versatile downlighting rather than industrial flood illumination.

Frequently Asked Questions

Yes. They are damp rated and water resistant, making them suitable for bathrooms and other humid locations when installed in covered areas.

Do they work with dimmer switches?
Yes. The fixtures dim from about 10-100% and are compatible with standard dimmers, though pairing with a modern dimmer yields the best performance.

Can they be installed where insulation touches the fixture?
Yes. Both the light and junction box are IC rated and airtight, so direct contact with ceiling insulation is permitted.
