OK, since everything I know about the problem and solutions I learned here,
I might as well reveal my deep secrets ;) ;) ;) :

I have taped 2 AAA cells together, have connected two poles and soldered
thin long wires to the two free terminals.  The other ends of the wires are
soldered directly to a 2.5V/0.8A Dr. T halogen bulb.  One wire is broken
serving as a "switch". 

I put the batteries in the film canister compartment after I pull the
rewind knob up (fits nicely).  I put the bulb by the film pickup spool
(there is just enough space, push it down).

I then go to the "darkroom" (boiler room in basement, lights off).  Stay
there for a few minutes for my eyes to get adjusted.  I then connect the
broken wires for the light to come one (a little bit of light will not
bother my eyes) and close the back.

Stay there and observe.  I can see the light leaking off the side.  I press
the back and the light goes away.  All I need to do is make the back fit
tighter.  When I am done, I open the back and disconnect the circuit.

I plan to use rechargeable AAA batteries because the halogen bulb is very
demanding in terms of amperage.

Try it!!!!  -- George Themelis
