Purpose - To test the lamp performance under high temperature
Criteria - Change in glass, electrode, fluorescent powder or gas materials, or major changes in sealing method on the electrode
Testing Procedures
Step 1 -
Leave the test lamp for 2 hrs at 25±2°C, 35~85% R.H. windless environment and then measure the lamp voltage, starting voltage, brightness and chromaticity.
Step 2 -
Place lamps at 80±2°C environment for 8 hours and place it at 60±2°C environment for 24 hours again.
Step 3 -
Place the lamp for 2 hrs in 25±2°C windless environment and then measure electrical characteristics, brightness, chromaticity and starting voltage again.
