GEC's Fulham Di-Fractor (Z8125) lantern is a variant of the Z8124 for 250W MA/V or 400W MA/V lamps. The lantern itself was top-entry only and could not host a gear inside. They were enclosed, featuring a Z6609 refractor made of glass. Nowadays very few of them are left, owing to replacement schemes over the decades.

Birmingham

A building along Witton Road has something very rare attached to it! What appear to be the remains of a GEC Fulham Di-Fractor lantern.

The bowl and lantern's rim are both missing.

The lamp-holder also remains empty.
