Croft Street, New Boultham, Lincoln Attached to a property on the original alignment of Croft Street is a basic top-entry wall bracket supporting a CU Phosco P283, for 35 - 55 Watt SOX (low pressure sodium) lamps. The P283 is the top-entry version of the (once) slightly more common P226, and seems to have been popular in the Lincoln area in the past. Its operational status is unknown, as a much newer tubular steel column is located the other side of a gated access that is adjacent the wall-mounted installation; however, as it does not carry any identification numbering for maintenance purposes, it could be abandoned.

With Croft Street having been realigned, it is now lit with 8 m columns for much of its length. The wall bracket may be an indicator of how the lighting along here looked prior to the realignment.

Whether disused or not, a 55 Watt lamp remains fitted within the P283. The rather angular design of the P283's canopy suggests that the lamp control gear is installed within it.

Interestingly, the wall-mount installation is likely to pre-date the P283, as two cast iron enclosures for 'Rhythmatic' Control equipment are positioned end-to-end on the wall (the lower one now houses a miniature photocell on its side for switching the P283 as required); as discussed on the Eastgate / Exchequer Gate page, this was an older method of switching street lighting, and employed a relay that would detect high frequency pulses that were generated at a main control point (for example, an electrical substation) and sent down the supply wires when the lights needed to be switched on or off.
