System OverviewSystem Overview
• Workspace specific
• Quality illumination
• Personal dimming control
• Occupancy sensors
• Daylight dimming
• Peak load management
• Scheduling/Reporting
Workspace specific lightingWorkspace specific lighting
• One Ergolight per standard workstation
• Positioned directly over work area
• Puts light where it is needed
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
Load shedding and sensor commissioningLoad shedding and sensor commissioning
• Avoid peak demand charges with load shedding• Commission sensors with the click of a mouse
