Our DWP09 20mm deep drywall LED profile is made for mud-in plasterboard installations. It makes smooth, clean lines of light with no apparent frames or borders. The profile is 56.6 mm wide and has a built-in channel depth of 23.2 mm and an internal height of 20.0 mm. It is made of durable 6063-T5 anodized aluminum. The 12.2 mm inner width is just right for 10 mm LED strips, including normal single-row, RGB, and COB versions. The strong material acts as a heat sink, which keeps your tape light cool and makes it last longer.
Why Choose This 20mm Deep Drywall LED Profile?
- Flush finish: The edges have small holes (perforated flanges) that let muck stick. It looks like part of your wall when it dries.
- Strong Heat Sink: The metal shell keeps the LED strips cool, which makes them last longer.
- Light without dots: It comes with an opal diffuser cover that snaps on. This spreads light evenly and softly, with no dots or hot spots.
- Fits perfectly: Made for regular drywall (1/2″ or 5/8″) to make sure it stays in place.
- Protects LED tape: Keeps dust and damage away and makes installation simple.
- trim to size: You may get it in 1 or 2 meters and it’s easy to trim to the right length.
