Recessed LED profiles sit inside a routed or cut groove so the diffuser finishes flush with the surface. House of LEDs stocks two recessed sizes: a shallow 25 x 7mm flanged profile that takes strip up to 10mm wide, and a deeper 24 x 14.2mm body for strip up to 12mm. Both ship with an opal push-in cover.
Choose the 7mm depth for 18mm board, worktop nosings and shelf edges; choose 14.2mm where you want more distance between the diodes and the diffuser. Every profile here is an open aluminium channel, so IP20, indoor. Other mounting styles sit in the LED profiles and channels range.
