Stylishly designed photo-cell controller. The remarkably inconspicuous NightmatIQ photo-cell controller impresses with its slim-line, sleek design and automatically provides perfect illumination night after night. The photo-cell controller gets to work on reaching the twilight threshold selected and simultaneously switches on all of the lights connected to it (max. 1000 W/ LED: 250 W). This reliably illuminates building fronts, premises, gardens, shop windows and other areas as soon as it starts to get dark – without having to lift a single finger. When dawn breaks hours later, the lights switch off again all by themselves. Benefiting from NightmatIQ, existing lighting previously switched on and off by hand can be converted to automatic operation in no time at all. To suit any need, the twilight threshold can be set to an ambient light level of 1 to 75 lux via a potentiometer (controller). Whether rain, storm or snow – with an IP54 protection rating, NightmatIQ ensures reliable performance in all weathers. The photo-cell controller comes in white and anthracite.
