8 Simple Light Control Strategies / ECMs
Occupancy/Vacancy Sensing: Automatically turn lights off or dim down when space is vacant. Integrate HVAC locally/digitally.
Daylight Harvesting: Automatically adjust light levels based on the amount of daylight in the space.
Scheduling: Lights automatically turn off or are dimmed at certain times of the day or based on sunrise or sunset.
High end trim/Tuning: Set target light level based on occupant requirements in the space. Reduce HVAC load (3 for 1 rule)
The Standard for Lighting Management Quality since 1953 w w w. n a l m c o . o rg
Controllable Window Shades: Allows users to control daylight for reduced solar heat gain and glare.
Personal Light Control: Allow users in the space to select the correct light levels for the desired task.
Demand Response: Reducing lighting load at times of peak electricity pricing.
Plug-load Control: Automatically turning task lighting and other plug loads off when they are not needed.

What type of LED product am I using?
LED Bulbs/T8 LED
• Designed to replace standard incandescent or screw-in CFL bulbs
• Standard Edison (E26) base sockets
• Integral drivers determine dimming performance (if dimmable)
LED Fixtures
• Variable in purpose (cove lights, down lights, 2x2, etc.)
• OEMs offer multiple driver options to support different control technologies and applications (dim vs. non-dim, 0-10V vs. DALI)
The Standard for Lighting Management Quality since 1953 w w w. n a l m c o . o rg
Dimmed Hot
What control type do I need?
Line Voltage Dimming - Forward Phase Analog – 2 Wire• Most common dimming method (150 million dimmers in use)
• Designed for resistive (incandescent, halogen) or magnetic low-voltage (MLV) loads
• Installed base not intended for LEDs, performance issues and compatibility problems likely
Hot (120/220/277V)
Neutral

The Standard for Lighting Management Quality since 1953 w w w. n a l m c o . o rg
What control type do I need?
Line Voltage Dimming - Reverse Phase Analog – 2 Wire• Typically used for ELV loads, sometimes perform better
with LEDs
• Less likelihood of acoustic noise due to no repetitive peak current
• Smaller installed base, usually require a neutral wire

What control type do I need?
Line Voltage Dimming - 3-Wire Analog• Fluorescent standard, control signal carried separate from
power
• Precise, less prone to noise, but requires a third line voltage wire
• Universal voltage, high power factor, multiple control types available
Switched Hot (power)

What control type do I need?
Low Voltage Control - 0-10V Analog Dimming• Analog control standard, low voltage wiring to each fixture in
lighting control zone
• Requires 0-10V low voltage control output AND line voltage switching
Switched Hot (power)
0-10V +/-AC Power

The Standard for Lighting Management Quality since 1953 w w w. n a l m c o . o rg
What control type do I need?
Low Voltage Digital Control - DALI / EcoSystem• DALI (Digital Addressable Lighting Interface) allows digital
addressing of individual ballasts/drivers in fixtures & status feedback
• EcoSystem (Digital Low Voltage Data System) allows assignment to daylight sensors, occupancy/vacancy sensors, timeclocks and multiple controls for one or many fixtures without added wiring
• Control wires are independent of power, no need to rewire line voltage
