ELECO GR501 Lantern Installations
The ELECO GR501 was a popular 35W/55W SOX lantern in the UK. It was a small lantern, with no room for an integral gear. Consequently, the gear was always in the column's base or a gear-box. The canopy was made from aluminium, and the lantern was sometimes painted white; The polycarbonate bowl almost always suffered some yellowing.

Against the white backdrop, a 26W SOX-E lamp's silhouette is clear, and a two-part photocell detector is seen poking out of the canopy.
The lantern is extremely narrow, having room for the lamp and photocell control, but nothing else.
