The yellow green 'Autolicht' bulb is old package, as 6v car tail light vanished long time ago.

Dr. Fischer 6V3A bulb and 6V6A bulb with 10mm offset, all works well with Minox enlarger.

Old Fischer 6V6A lamp markings:

• Yellow/green Autolicht box, stamp 6V 6 Amp.
• Silk screen 6V6A 1521 on bayonet lamp base

New Fischer 6V6A lamp markings:

• Green 'Dr. Fischer' white box, stamp 6V 6 Amp.
• Concave stamp on bayonet lamp base: 6V 6A 5A (?)

Dr. Fischer 6V5A Bulb for Minox Enlarger I

• Single contact bayonet, diameter 15mm, silk screen "6V 5A 1521"
• Glass bulb diameter: 19 mm
• Height: 55 mm
• Filament coil to contact: 35mm, offset =0.
• Filament coil 5mm 11 turns.

Fischer Lamp vs Other Lamps

The following picture shows clearly the differences between Fischer 6V6A bulb and other replacement bulbs, for example, GE 1133 6.2 V 3.9A bulb.

• GE 1133 bulb filament is off focus by 10mm
• GE 1133 is off axis by 5 mm
• GE 1133 filament is perpendicular to bayonet keys, while Fischer one is parallel.
