Acuity stopped by our office with a new series of recessed lights from Gotham, called Evo Architainment Color. There are three new platforms that they introduced that all work within the 4" round and square downlight and wall washer apertures. There is a dim to warm LED, a color tuning and an RGB option all using Nichia LEDs. With the Dim to Warm option, they are trying to keep it as close to the black body curve as possible. The fixtures dim from 3000K to 1800K. Dimming can happen with either 0-10V or DMX. With 0-10V it requires a power pack in order to work without DMX. Color tuning fixtures have a range from 1800K to 4300K. With the RGB fixtures, you are able to change color and intensity.
