Quality Direct/Indirect LightingQuality Direct/Indirect Lighting

• Center lamp distributes light

upwards, reflects off ceiling

• Provides uniform ambient

light / Softens shadows

• Eliminates cave-like room

appearance

• Outer lamps deliver extra

light on desk-top for

enhanced visibility

• Louvers control glare on

computer screens

Constant up-light in open spacesConstant up-light in open spaces

Personal Dimming Daylight Dimming Occupancy Sensing

Up-light unaffected

Occupancy and daylight sensingOccupancy and daylight sensing

• Overhead sensor location= reliable sensing

• Gradually dims outer lamps to 10% after

time delay

• Holds at 10%, before turning lamps off

• Over 30% energy savings in window-

adjacent locations

• Gradual dimming avoids

sudden changes in levels

• Maintains constant light

level at work plane

Personal Dimming ControlPersonal Dimming Control

• On-screen control panel

• Users select preferred light level

• Ceiling light stays constant

System-wide managementSystem-wide management

• FM has full control over entire Ergolight network

• Entire network can be gradually dimmed for load shedding

• Events can be scheduled on daily/weekly/monthly basis
