Operating Notes - GE Lamps Brochure

Operating Notes

Caution notices are included with all lamps. Users are urged to read and comply with these.
Operating precautions
All lamps in this catalogue must be operated with a series fuse in the circuit, as directed in the
Technical Digest.
Lamps of quartz construction use a gas filling at a pressure higher than atmospheric and as the lamp
can in rare instances shatter in use, suitable shielding techniques should be employed where
appropriate. Also protect the lamp from mishandling, scratches and abrasions, and do not operate at
above correct rated voltage.
Operating position
For good performance lamps must be used within specified limitations on operating position. The
following abbreviations are used in the lamp tables to indicate these limits:
BD - Base Down. Operate only vertical, base down.
BU - Base Up. Operate only vertical, base up.
BDTH - Base Down To Horizontal. Do not operate with base above horizontal.
Horiz. - Horizontal. Operate only in horizontal position.
