To insert new lamp:
1. For best performance of Halogen lamps, remove any dirt or
fingerprints from glass with a clean cloth moistened with 70%
Isopropyl Alcohol before inserting lamp. Failure to follow clean-
ing procedures will result in permanent stains on the glass with
reduction in light output. Average lamp life is 20 hours of on-
time.
