LED strips provide excellent lighting for under counter-tops lighting. The LED strip is thin, very bright and has a 3M tape adhesive for mounting to surfaces but as some designers and electricians have found, there can be some “spotting of LED lights” on shiny dark counter-tops such as Granite (and other similar reflective materials).
Aluminium Profiles diffuser Lens in Frosted and Opaque reduce or eliminate the spotting effect and most importantly, extend the life of the LEDs because the channel acts as a heat sink (although the strip produce little heat). Another added benefit is it protects the LED strip Light from splashes and makes cleaning the profile much easier. It is recommended to be used with Double and Triple Bright Type A (without coating or cover) series of LED strips.
