WRTL 2822

This road tunnel fitting is designed for installing in a recess within a tunnel wall, although surface-mount versions were produced too. How it ended up at Derby is a mystery, but it never ended up being used - I wonder if it was supplied as a sample for evaluation purposes in the event that one of the City's (relatively uncommon) underpasses required relighting.

This fitting is a very simple construction - essentially, it is a clear-topped box with a 90 Watt SOX gear set positioned inside.

Unlike the Bergo 38SP, the 2822's front panel is held in place with regular (non-security) grub screws, although they are still recessed. The ballast and ignitor are made by Parmar, with all wiring being especially tidy. The ignitor was manufactured during week 48 of 1997 (the 24th - 30th November), whereas the capacitor is a little older, and was produced during week 10 of the same year (the 3rd - 9th March).

 The prize of a quantity of air goes to first person to spot a very obvious mistake with the fitting's label - think about the type of lamp it is meant to use! The mention of GEC is also interesting, as they had ceased to exist some years earlier.

The fitting was powered up on Saturday, 10th June 2006. The sides of the reflector were angled to allow both sides of the arc tube to be visible - therefore, maximising light output.
