Data Sheet

3
3.2.1 The testing of the electrical and optical characteristic should start when the lamp has been
running for more than 3 minutes under the required testing current. The lamp should be placed
horizontally.
3.2.2 The ambient temperature is 25℃±2℃,and 65%±20% for the ambient humidity without any air
movement.
3.2.3 Testing Equipment
Testing Item Equipment
Input voltage、current Digital multimeter DT9806
Starting volt、lamp volt 1:100 high pressure detector/Tektronix TDS 1012B
Lamp current Fluke（8086 A）
Surface luminance Colored photometer（BM-7 Topcon）
Color Temperature 、
Chromaticity
Colored photometer（BM-7 Topcon）
3.2.4 Working condition：-10℃～80℃, relative humidity below 70%，Saving condition：-20℃～90
℃ relative humidity below 80%.
3.4 Testing method:
3.4.1 The testing circuit of starting voltage, lamp voltage, lamp current is as the pictureⅠ.
A. The length of line d-e and f-g is both 300±10mm(without the equipment for IL)
B. The lead wire for testing the loop should not be placed in parallel otherwise it may influence
the testing accuracy.
C. When IL is tested, disconnect the VL testing equipment. When VL is tested, connect the IL
testing equipment to the wire.
D. Lamp should be tested on the special testing lamp-support. The background should be black
with no reflecting light.
3.4.2 Note: The testing result would be different when testing equipment varies.
