Our Trimless "Plaster-In" Aluminium profile is available in 2m long. Upon installation, you can plaster across the flanges which allows you to create a stunning, clean lighting effect across walls or ceilings. It is supplied as standard with a frosted diffuser and 2 x end caps. As well as the great look, an aluminium profile also acts as a heat sink, aids cooling and extends the life of LED Lighting. The good looking frosted cover also reduces glare and can remove the "Dot" effect commonly associated with LED.
