Measuring EL Life
EL Life is typically measured in time-to-half luminance (THL). THL
below is 5000 Hours.

Factors Affecting Life of EL
Lamp Construction
• Phosphor Technologies and/or Color
• Environment (Temperature, Humidity)
– Life decreases as temperature and/or humidity
increase
• Driving Conditions (Voltage, Frequency)
– Life decreases as voltage and/or frequency
