Guidelines on the Application of Dimming to High-Intensity Discharge Lamps

NEMA LS 20011 S2022 (Previously LSD 14-2012 (R2019) | Status: Active | ID: 100654

There are two basic categories of lamp dimming systems in common use:
a. Step-level (including bi-level) power reduction, typically associated with magnetic ballasts.
b. Continuous or variable dimming, typically associated with electronic ballasts.

Not all systems will provide the same performance with all HID lamps, and not all systems are optimized for all HID lamps. Consequently, lamp and ballast manufacturers should be contacted to confirm that lamp/ballast combinations are compatible.
