ROOF is a suspension light fixture designed by David Abad for dab in 2004. The designer wanted to create the most versatile model possible with optional diffusers and even with the possibility of working without one for a less controlled lighting. This model can carry one of the following diffusers: • a clip-on tubular perforated aluminium sheet; • a plastic diffuser that comes in transparent red, opal white or transparent grey; • an anti-shine, aluminium strips diffuser which can complement the previously mentioned plastic diffusers. It has a standard length of 125 cm and its light source is a 54w T5. With all of these options within such a simple and clean design, David Abad multiplies the light fixture’s potentials, thereby allowing the user to participate in the resulting visual effect, may it be for home, office or any other environment.
