Local Thorn Triumph 2s

Triumph 2s are used on the Derby City Council-owned part of the A52 dual carriageway. The lanterns were installed in early 2003; replacing Philips MA 60 180W SOX fittings. They currently run 250W SON-T lamps although it is thought that they might be converted to metal halide in the future. The lighting on the slip roads was not changed and so these are still lit with 135W SOX lanterns - mainly Philips MA 50s.

Following column replacements in November 2011 as part of Derby's Street Lighting PFI, the Triumphs installed along this road disappeared; the new columns being fitted with Philips Iridium² lanterns (the 'updated for 2011' version of their regular Iridium lantern).
