The Donar DN-27219 (JC 6V 20W/SP) is a specialized halogen replacement lamp designed specifically for Topcon slit lamps. Unlike a standard G4 bulb which has plain pins, the "SP" (Special) version features a pre-focused metal disk base (often referred to as a flange or copper plate) soldered to the G4 pins.
This disk is critical because it ensures the filament is perfectly centered within the slit lamp's optical path, maintaining a sharp, uniform beam during eye examinations.
