When leaving late one evening from Avery Hill, noticed how a bit cold of mist can effect the haze of lighting. Very spooky, but enclosed by the darkness of the sky in contrast to the effective downlighting (to avoid light pollution) of the white lights (high pressure sodium i believe), compared to the orange (low pressure sodium, more efficient for luminosity to power consumed than the high pressure ref: http://en.wikipedia.org/wiki/Luminous_efficacy).
The white is more up lifting and 'safer' in a car park situation, but putting that aside for the moment, the white just looks better due to ability to bring out the green (ie white spectrum compared to orange) in the planting. Thoughts for both parks. I know blue works well with humans in low light as it works well with our non colour sensors (what ever they are called) in the back of our eyes. Which i believe are there for low light (ie the less light the more grey and white landscape we see) or is my school boy memory playing tricks again? Normal back of post card please.
Getting 'A back to the Future' flash back, expecting a Delorian to come screaming out of know were doing 80mph+ with maybe a long haired version of Tom Turner at the wheel after an adventure in some Renaissance carriage park (or should that be stable yard), he would so love that.
Wow that's a good analysis you have done! I didn't notice that much. But it makes sense.
ReplyDeleteThanks, always had an issue with orange lighting, just seems we are missing out on potential colour at night, rather than the fug of Orange. It was argued that it was better for fog/smog, but since the clean air act we don't really get that much fog, bring on the white lights, rant over.
