Approx 16cm long, 4 & 6 cm dias.

Oddly textured end to the lamp holder, could be corroded, but also looks like it was manufactured this way. Doesn't impact use of the light as far as i can see. Otherwise all look ok. Some dirt and wear & tear. Cable and plug look ok. Glass has some scratches.

I presume there is a knob missing from the small spindle, which does turn, but only 1/4 of a turn or so.
