DW Windsor Excel 500 Lantern Installations

This is another one of DW Windsor's Optima range. The Excel is very, very similar to the Stratum; the only difference of note is that the Excel is slightly taller. The Excel is available in two sizes, the 450 (small, documented separately) and 500 (large). They were once sold as HID lanterns, with lamp-types including metal halide or high-pressure sodium, but nowadays these lamps have been superseded by LED technology - and the Excel has been adapted to use such a light source. These versions could have LED boards populated with 64 LEDs only, compared to the 450 which could also include 16 or 32.

Several installations consisting of DW Windsor Excel 500s and Stratum 450s exist along London Road. The Excel 500s take charge of lighting the main road, while the smaller Stratum 450s are responsible for lighting the footpath behind each of the columns. It appears the Stratums are mounted at roughly 5m, with the Excels being located at 10m.

Another installation on the same road:

It appears these run 150W SON.
