This is the PP bulb and base (54.9g) after removing the red wire soldered on. It's shell houses a small, thin glass filament bulb which is the light source for the projector.

The mild steel base piece (37.8g) twists and pops off easily from the bulb. This component allows the bulb to be connected to the rest of the circuit easily, through soldering and screwing it in.

Unsure on how to further dissect the base piece, however I am certain is it multiple components riveted and screwed together. Some of the 'screws' have no slot, just completely smooth, and the few screws available were on so tight I was unable to remove with my thin slotted screwdriver.

Bulb Length: 92.9mm, Base Length: 36mm

Bulb Diameter: 42.6mm

Bulb Width: 18.4mm, Base Width: 34mm

Height: 20mm
