Thanks for the information. I have ordered 10 bulbs (@38¢ each) from
Jamco, and I will soon find out how much of a pain it is to replace the
bulbs. If replacement frequency is too high, I will follow another
person's suggestion and replace the bulb with a 6.3V version. In your
estimated life for the 1850, you listed the estimated life as "1,5000" so
I'm not sure if you meant 1500 or 15000 hours. 1500 hours seems a bit
short. :-)

Sorry John - typo. CML shows it as 1,500 hour estimated life --
yes that is SHORT -- if left on full-time - that is not even a year.
I usually substitute for same or similar brightness
and longest bulb life from CML charts!!

LED is the other choice -- but liight characteristic differences -- do not
match all applications.
