Do you know that... ...Protecting is not the only one function of Aluminium profile for LED strips. Using covers we can get two different effects. If we want to spread the light, we should choose milky / Frosted one. In opposite, clear cover will focus the light emitted by each one diode. Why Aluminium? Aluminium is one of the best heat conductor. LED diode do not emits as many heat as the traditional light bulb or halogen, but we have to remember, that even if we can't feel it, every light source emits some heat. When you stick the LED strip directly onto the wall or wood, its durability will be even 10 times shorter! That's why usage Aluminium profiles for LED strips is very important.
