Q. How do I change the lamp in my Beseler Cadet II?
A. Unscrew the three small screws at the base of the lamphouse and
lift the lamphouse off. Unscrew the lamp when cooled and replace with a
PH140 lamp. Refasten the lamphouse to the enlarger.
Q. I have a bessler 23C11 enlarger that needs a PH140 bulb. I
a broken bulb (GE) with a new one made by a different manufacturer
A print that originally took 12 seconds, now, with the new bulb, only
7 seconds. Obviously, all my times are going to be off. Is this normal?
Is a stronger bulb better? Please help!
A. This is normal. Bulbs do not project an equal amount of light over
the life of the bulb. The older GE bulb probably had shorter print
when it was initially installed. While bulbs are manufactured to high
exacting standards there will often be a small difference between
The strength of the bulb should be equal to the standards required by
equipment manufacturer. Shorter print times equal higher productivity.
Longer print times allow for easier dodge and burn manipulation.
Q. In our community college art department darkroom we use PH
on all our enlargers. At $9+ a bulb our budget is creaking. Does anyone
know a good cheap substitute (a bulb, a modification of the enlarger,
both) for a 75w bulb that would work in a B & W Beseler
A. It is not recommended to use any other bulb than the bulb required
by the equipment manufacturer. Better pricing is available when bulbs
purchased in quantity. If you are replacing bulbs more often than the
hours the bulb is rated you may have an equipment problem.
Q. I have besslers in my darkroom that have 2 different types
bulbs-I believe one is a ph 140 and the other is a 111 something. One
round in shape and small-one is more the traditional light bulb shape(P
140).I find the 140 prints better-can anyone explain the pros and cons
of these two light sources??? I hope I have the numbers correct. Is it
expensive to switch all the enlargers to the 140 bulb? Does besler just
sell the part that you screw the bulb into?
A. The older style bulb is the small one with the pin mount base. The
newer being the larger screw in style.
Beseler sells a kit to upgrade to the newer bulb. I would contact
directly or check in with a repair shop which handles darkroom
Enlarger Bulbs are widely used in motion picture lighting.
