Canless and wafer downlights are thin LED recessed lights that mount straight into the ceiling with a remote junction box, so no separate housing is needed. They are a fast choice for remodels, basements and new construction. You'll find round and square wafers, canless gimbals and regressed or deep-regressed low-glare models from Lotus LED Lights, Luxrite, Halo, Satco, Nicor, Westgate, Nora Lighting and Keystone.
What should I check before ordering? Confirm the cut-out size (2-inch, 4-inch and 6-inch are the most common), the ceiling thickness and the dimmer type. Many models offer selectable color temperature (CCT) from 2700K to 5000K, wet-location ratings for showers and soffits, or 347V-capable drivers for commercial jobs.
