[pure-silver] Re: Enlarger Lamp Life

Well I have had more of an issue with bulbs when the enlarger had to be moved 
for any of a number of reasons.  I ended up just keeping spares around.  Try 
www.bulbdirect.com   As cheap as the bulbs were for the enlarger I have now, it 
didn't make sense to worry about it.  Now my enlarger had apparently been 
rewired to take a cheaper bulb, but it worked and I don't have any problems 
with it, except when I have to move the table back for the wife to clean behind 
the table in the laundry room.  Trust me its far less aggravation to buy a bulb 
than try to explain to the wife why the table shouldn't be moved.  I tried that 
over a decade ago and learned that there is only one acceptable answer and it 
has only two words.  Yes Dear.
