This 1 metre Tech-Light profile is made of high-grade aluminium and has a white finish. It is 11mm in width with an internal width of 9.4mm. The profile has a depth of 7mm. The white colour means this particular profile is an all-rounder and can be used in a wide variety of settings without the colour taking away from the LED strip itself. Furthermore this product helps disperse any heat from the strip which improves the lifespan of your LED strip. All Tech Light LED profiles are protected by anodization layer which protects them from the elements.
