A trip up to Lancashire this week gave me the opportunity to have a second look at those LED lanterns on the A5, and also in daylight for the first time. I also grabbed a few photos as dusk was setting in. All photos were taken yesterday (1st February 2011).
The LED lanterns, mounted on the previously installed 12 metre columns, do a pretty good job of lighting the main carriageway.
But compared to the MA60, and even many equivalent SON lanterns, the lantern's size is absolutely tiny.
A side profile of the modern-looking new lanterns. Anyone have a clue as to who makes them, and how much energy they save compared to other light sources?
Despite their tiny size, the lanterns pack a punch - in this photo the light is compared to the light given out by the SON TrafficVisions mounted at 10 metres on the slip road.
One of the advances in technology seems to be the near 'invisibility' of the lanterns when viewed from the side. Compare the numerous lanterns on the main carriageway - if you can see them - with the flat-glass trafficVisions on the slip road.
A zoomed-in version of the above photograph. The street lighting in the rest of Tamworth (in the distance) is clearly visible to the naked eye, but the new LED lanterns are invisible. Only the patches of light on the ground and the lit-up columns offer a clue as to where they are. How's that for full cut-off lighting!
