Note 1
Substantive input voltage variation will affect lamp performance characteristics, including light output, lamp life, consumed power, color temperature, etc. Generally, higher voltage use will increase light output, power, and color temperature and will lessen lamp life, and lower voltages will have converse effects. However, the relationships are linear only near the rated input voltage value.
Note 2
The time after which 50% of test lamps were no longer operating.
Note 3
These ratings are determined by the lamp manufacturer based on laboratory tests under controlled conditions. Your own field results may vary.
