45-Degree Corner Profile - How It Works This aluminium LED profile is designed to fit into 90-degree corners , but uniquely positions the LED strip light inside it at a 45-degree angle . This provides alcove shelving, staircases, and kitchen under-cabinet corners with lighting that doesnt limit illumination to the surface the fitting is mounted on, but rather directs it at an angle. So, what you get is light thatpoursinto the room, improving visibility and reducing wasted illumination . Instead of concentrating all the beams o n the worktop, the LED strip in this profile can help improve the rooms overall brightness without additional overhead lighting. It should be noted that only LED strip lights up to 12mm wide   can fit in this aluminium LED profile, so double-checking your lights is recommended.
