Philips XGS 103

Lantern acquired in August 2019.

This XGS 103 was one of a number that were installed in and around the Rempstone Drive area of Chesterfield. As a trial, all of these lanterns had their 35 W SOX lamps and gear trays removed, and retro-fitted with an LED gear tray instead. Following feedback, the decision was taken to fit purpose-built LED lanterns instead, owing to the converted lanterns producing a peculiar light distribution, which was caused by the original refractor bowls creating a stripe effect on the carriageway.

From the side, this XGS could be mistaken for being a standard SOX version of the popular Philips lantern, with its GRP canopy and aluminium rear section, enabling the lantern to be mounted post-top to a column shaft.


The GRP is in typical condition for its age - rather grubby, with fibres beginning to shed quite mercilessly.


The NEMA socket carries a manufacturing date of December 2003, whilst the Royce Thompson Oasis 2000 photocell that was fitted to it was manufactured earlier in the same year.


Only when seen from below does the different light source begin to be apparent.


With the plastic cover panel removed, the inside of the aluminium section reveals a number of spider eggs, as is to be expected.


Opening the lantern's bowl reveals the replacement LED gear tray that is fitted in this lantern. The LED circuit board contains 72 LED chips, and is positioned in the centre of the lantern, in the approximate footprint of where the 35 W SOX lamp would be situated.


The inverse of the gear tray serves as the location of the small driver unit.


The gear trays are made by Harvard Engineering, with the drivers being the Company's 'coolLED' type. Notice that the project reference code incorporates 'MI 26'; the name allocated to older XGS 103s...what do you mean, "pedantic"?
