1 This is the time after which 50% of test lamps were no longer operating. Average rated life is based on 10 hours/start.

2 These ratings are determined by the lamp manufacturer based on laboratory tests under controlled conditions; your own field results may vary.

3 CERN does not recommend use of the materials in Super-Vutron (CSPE/EPDM) cable above 108 R (106 Gy).
