The DORA LED downlight is a square luminaire with a very low height designed for offices, schools, corridors, hotels, shops, bathrooms and other public areas. It comes in three versions, so it can be used in suspended ceilings as well as on concrete ceilings.

DORA R is recessed into the ceiling. It measures 130 × 130 mm or 230 × 230 mm and is only 37 mm high.
DORA S is surface-mounted on the ceiling and measures 255 × 255 × 37 mm.
DORA A is recessed into the ceiling, has a micro-prismatic diffuser and IP 44 protection, so it is also suitable for bathrooms.

DORA R and DORA S have a double parabolic reflector with lenses that limits glare to UGR ≤ 19, so the luminaire meets the requirements for lighting computer workplaces. Its efficacy reaches up to 151 lm/W.

DALI dimming, an emergency lighting module, a black reflector and a body colour of your choice (RAL) are available on request.

DORA guarantees a lifetime of up to 60,000 hours and significant energy savings. It comes with an extended 5-year warranty.
