Trying to get it as fair as possible, looks like Gav was correct - Urbis is a bit of a glare bomb!

Glare bomb yes, but this is due to it having the wrong lamp in, at this mounting height you only need a 50watt SON-T.
Street lighting in the UK is way over the top, if you look at Al`s photos, the Australians use 50watt MBFs at heights WE would use a 100watt SON-T.
I remember showing him a 90watt SOX lantern at 8 metres, (the norm in the UK), and he commented that why would such a bright light be mounted at such a low height?
As a street lighting planner, my choice would be 50watt SON-T on sideroads at about 6 metres, with 70watt being at 8 metres.
There is far too many 70watt SON on 5 metre columns here.

our streets are 150w son Indal Arc 80,s on 5m columns
