Local DW Windsor Kirium Pros

The Kirium Pro LED lantern began to make an appearance in Derby in early 2019; possibly, as a change to the City's preferred LED lantern, the OrangeTEK AriaLED. Multiple versions of the lantern were used, depending on the size of the road and its particular illumination requirements.

This Kirium Pro 1 mounted to a 5 m column in Littleover replaced a bracket-mounted Philips XGS 103 35 W SOX lantern.


An unpainted section of the column, from where the bracket was situated, is visible below the lantern. The lantern itself is coloured light grey to RAL 7035.


16 LEDs are situated in the centre of the lantern's optic, although there is space for double that figure in this version of the Kirium.


A small number of Kirium Pro 1 lanterns were installed on new mid-hinged columns on a footpath that passes alongside the A38 between Queensway and Kedleston Road.


These lanterns are painted black (RAL 9006), but the LED quantity remains the same.


This Kirium Pro Mini is one of several installed on Bramblehedge Drive in Sinfin. These lanterns replaced Philips Iridium2s, again in 2019, that were installed when the housing development was new in 2014. Despite the relatively new nature of the original lanterns, changing to LED must have been a more cost-effective solution, particularly as the Iridium2s would have been afforded by the company that constructed the development.


These tiny lanterns measure 390 mm (1535 inches) in length, 110 mm (433 inches) in depth (excluding the post-top spigot and 227 mm (893 inches) in width.


Once again, 16 LEDs are installed; the maximum quantity available with this version of the Kirium.


From the smallest lanterns in the Kirium Pro range to the largest, now - a number of Kirium Pro 3 lanterns were installed on the A52 Borrowash Bypass as part of the road's widening at its junction with the Wyvern Retail Park.


Coincidentally, these lanterns were also used as direct replacements for Iridium2 lanterns that replaced Thorn Triumph 2 lanterns in 2011.


The lanterns are equipped with Telensa Telecell Controllers fitted to their NEMA sockets; these control the operation of the lanterns remotely.


Adaptors are fitted to the narrow side-entry brackets, in order to allow the much wider lantern spigots to attach securely.


From ground level, these lanterns seem rather large and bulky.


Then again, they are - the lanterns measure 1010 mm (331 ft) in length, 167 mm (657 inches) in depth and 415 mm (1633 inches) in width.


These lanterns accommodate 96 LEDs - four groups of 24 LEDs.


The maximum quantity of LEDs that this version of the Kirium can accommodate is 128 - I expect that sunglasses are provided as standard at that amount!


The lanterns weigh 17.5 kg (38.58 lb) each.


Not all of these lanterns are fitted to double-arm columns; some are mounted post-top.


The wide surface area of these lanterns makes them an ideal podium for wood pigeons to use and survey all that lies below!


A small number of single-arm examples exist too.


An older version of the Telensa node is fitted here; these incorporate a more prominent antenna than the newer examples do.
