Leviton's photocell sensors precisely monitor either task or ambient light levels. As part of a Leviton lighting and energy solution, photocells work with other components in the system to automatically adjust light levels to a user defined level. Photocells are most suitable for installation in rooms with windows and open spaces receiving substantial ambient light. Photocells must be hardwired to a compatible Leviton lighting control system. The photocell measures ambient light in a specific area and sends this data to a dimmer or relay that, in turn, adjusts fixtures to a constant lighting level as measured in that specific area. Daylight harvesting is achieved as lights in a room (with windows or significant, artificial ambient light) automatically brighten or dim depending on how much light the photocell detects.

Commercial Applications
PCATR atrium photocell with opaque dome lens filters 33% of light level in upper atrium
Default setting 215 to 2690 FC sensing range, can be field adjusted to 2690 FC maximum sensing range
Lowers electric bills by reducing usage of lighting where ambient natural light is also present
Lumens maintenance opportunity compatible
Indoor photocells designed with a flat Fresnel lens looks downward in a 60 deg cone of reference to measure actual light on the work surface and reduce the influence of stray light striking the photocell from nearby windows or incidental side lighting
Measures light from any source in the visible spectrum within a 60 deg cone or 180 deg angle of response depending on the model
