LED spotlight unit with one LED spotlight head size maxi, equipped with a lens system for high-quality accent lighting in museums and exhibition rooms. Combinations of LED boards, lens, and foil result in uniform light distributions with high intensity and soft transition, without scattered light from the light cone. The luminaire features a 3-phase universal adapter with control gear in the luminaire, fitting: 1/15.5W, colour rendering Ra > 90, colour temperature 3000 K. It has a WIDEFLOOD beam characteristic, colour tolerance: SDCM 2 initial, and premium-selected LED boards. The luminaire luminous flux is 950 lm, with a luminous efficacy of 61 lm/W and a service life of 50,000 hours at 90% luminous flux. It includes illuminance dimming, with dimming directly above the luminaire, and provides flicker-free light (amplitude dimming). The light head can be rotated 360° and swivelled 90°, made of die-cast aluminium painted black. The optics consist of a glass lens and a plastic foil, and the front ring is used for glare control and for holding foils. The luminaire wattage is 15.5 W, mains voltage is 220-240V/50/60Hz, dimensions are 150x65x157 mm, and weight is 0.66 kg. Note: Horizontal and vertical wall mounting is permitted, but it is not suitable for point outlets. The foil can be replaced with other light distributions, and the ring louvre or the extended anti-glare tube can be replaced with the front ring.
