Photocells

Photocells

Leviton’s Photocell sensors precisely monitor 

either task or ambient light levels. As part of a 

Leviton energy management system, 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.

DAYLIGHT HARVESTING

With Daylight Harvesting, ambient (often natural) 

light supplements in-room, artificial light in order 

to keep a constant lighting level while saving 

energy. This constant level is programmed into 

a compatible control device. Once hardwired to 

the photocell, the dimmer or relay will receive 

the photocell’s real-time light measurement and 

maintain a steady level within the photocell’s 

area of detection.

RULES OF OPERATION

Measured light level = Light Maintain Level 

Action: Output to lights remains constant

Measured light level < Light Maintain Level 

Action: Lights are brightened

Measured light level > Light Maintain Level 

Action: Lights are dimmed
