This aluminium profile by the creators at Tech Light is made of high-grade aluminium and has undergone the anodization process which means it is fully protected against corrosion. This product has an internal width of 24.5mm and a depth of 25mm. This P22-3 profile acts effectively as a heat sink which dissipates heat from the strip housed inside ultimately improving the longevity and reducing dulling. This product can house up to 3 LED strips at once. All Tech Light LED profiles are protected by anodization layer which protects them from the elements.
