Perhaps they replace temporary lighting? During road works they place temporary HPS lighting.

No I am almost sure the HPS lighting wasn't temporary

Ok, I prefer LPS lighting.

Why the crew hold, moving and install this lamppost with the fixture already mounted to it. I think this may damage the fixture. In Israel i saw the lighting crew of Haifa municipality do this only with fixtures mounted to arms that connected to regular wooden electricity poles. In indepent lamppost where the electricity line is underground, i saw many cases that lighting crews first install the lamppost itself without the road light and then the road light. But this may not be always like this.
Regarding the LPS post: Even through the LPS lamps have lower optical control in the fixtures because of it size, i bet this fixture will perform much better with less power and without mercury in the lamp. But as far as i know, because LPS is considered an antique light source and it is rare today then in the past, Like in computing and automobiles this installation may be more expensive then a 250W HPS installation despite the much simpler fixture, equipment and lamp costrution.

Really? The lamp construction seems quite involved to me. There seems to be lots more shaping and coating etc.

Hey! I think the reason this lamppost contains a LPS fixture is because it is move to here from another location.

I have seen it often in the Netherlands that they raise a post with already the lantern mounted on it.

I think not. The post looks like new.
Sometimes you see them install the post without the lantern, but not often. It's easier to mount the lantern when the mast is on the grount then when it's standing.

@dor123:
They do this in the UK as well, put the new columns up WITH the lanterns on them, I suppose it saves the electricians having to bring the lift truck out as well
