Our DWP21 ceiling-mounted LED cove light drywall profile provides you with ideal, smooth lighting. This trimless, recessed LED cover light drywall profile measures 94mm in width, 34mm in depth, and features an internal channel that is 21.36mm wide. It fits nicely in ceilings made of drywall or plasterboard and can hold LED strips that are up to 15mm wide. The profile is made of durable anodized aluminum and works as a heat sink to assist your LED strips in lasting longer by keeping them cool. Its slanted shape sends brilliant, steady light down at the best angle, making sure there is little glare and a lovely, dotless output. The fixture disappears after being plastered over, leaving you with a clean, smooth architectural lighting finish.
