Replacement Light Bulb for Wild Focomat I IB IC Photographic Enlarger - 120V 75W 1200 Lumens

Replacement for Wild Focomat I, IB, IC and similar photographic enlargers that require a 120 volt 75 watt incandescent bulb in A21 shape. This part matches the original 1200 lumens output at 3000K color temperature with a white bulb finish and 100 hour rated life.

Photographic enlargers demand consistent, reliable light sources to produce accurate prints from film negatives. Using the correct incandescent bulb ensures even illumination across the negative carrier without introducing unwanted color shifts or hotspots that can ruin an otherwise perfect exposure. This 75 watt option operates at standard household voltage and draws only 0.625 amps, matching the electrical characteristics of the original equipment exactly.

Darkroom technicians appreciate bulbs that install quickly and perform predictably session after session. The A21 shape combined with the white internal coating diffuses light gently while the medium screw base threads securely into the socket without adapters. Because this is a traditional incandescent lamp rather than an LED or fluorescent substitute, it maintains the spectral qualities enlarger optics were designed around, preserving contrast and tonal gradation in the final print.
