The lights shine clear through the sodium haze

While out on my early evening perambulation with my dogs on the Northside the other evening, I noticed that a number of the street lights had been changed from the usual dull orange, to a sharp and bright white light. Ok, no problem with that. A few evenings later I noticed that whole streets had been changed over to these.

Now my street has been converted to these “Auschwitz spotlights”.

It’s not a case of replacing bulbs when they blow, but of replacing whole street sections. Which must be an expense. The new lights are bright and sharp, too bright for my tastes. They also cover a wide arc, which is fine for walking, but not so good if they come in through your bedroom window, and like me, you need pitch black to sleep.

Anyone have a clue as to the rationale and rhyme and reason for these new lights?

Are they “an experiment”, “more green,” “less expensive in the long run,” “mandated”, “just done to annoy Pommy”?

The lights shine clear through the sodium haze
The night draws near and the daylight fades
But there’s a voice in the distance quiet and clear
Saying something that I never ever wanted to hear

Hopefully they don’t improve the lighting in the carpark at Dickson Woolies. We wouldn’t want to spoil our local lovers lane now would we?

I would like to see one of these new suburbs trial having lights in a kind of ‘kerb’ at the side of the footpath, on the house side, so they shine away from the nearest house. Would fulfill the need for lights on the path itself, without creating so much light pollution.

just paint the footpaths with glow in the dark paint. you would be sure to see the footpath then.

Funny, I feel much less safe when walking a lit up path but with darkness around me. It’s much easier for anyone else to see me and much harder for me to see them.

I thought the orange lights were used in Canberra to reduce the effect of light interference on Stromlo observatory.

They may last longer and use less energy

We’re now at post #38 and I’m the first to comment that PB’s pic isn’t straight. Where are all the normal critiques of PB’s work?

I like the effort to keep the camera level though PB and now all we have to do is let the ACT Gov’t know they’re building lopsided roads:)

An JB, 3 set of curtains? What were you thinking? Think of the additional fading when daylight savings comes back around!

Just moved into a new place in Belconnen, on a battle axe block. There is a pathway that runs behind the house and a park behind that. The light just outside the house (and main bedroom), is way too bright and lights up the whole side of the house makes the room quite lit up, even with the blinds shut. It’s a rental place, so I can’t really install a proper curtain setup…anyone have any suggestions?

Call ACTEWAGL and complain.. I’ve seen/heard of occasions where they’ve been able to modify the lighting for residents’ comfort.

Like the lightbulbs in your house, the lights are normally a bit brighter when they first install them, they get a bit more dull after a couple of weeks. You also get used to them too.

No – I agree with that; muted light is vastly preferable … but some posters have suggested no lights at all, which I think would be a bad thing.

deezagood: I agree, but the issue is whether they need to be so bright and shining into people’s windows…

You don’t realise how necessary street lights are until they are no longer there. Our whole street’s lights went down over Christmas (ACTEW wouldn’t admit this, but I reckon the bloke down the road with the Griswaldesque Christmas display was to blame) and it was really dark and creepy. Scary even just putting the bins out. Tripped over objects on the way to my early morning run. Couldn’t wait to get the street lights back.

#27 – Granny, you’re the best… LMAO

Streetlighting initiatives
Current streetlight maintenance objectives are focused on reducing energy consumption and maintaining public safety. In recent years, Roads ACT has sought to replace mercury vapour lighting along the main road networks with relatively energy efficient high pressure sodium lighting. Further, as newer suburbs are developed, high pressure sodium lighting is installed along roads, and paths, where necessary. For the Tuggeranong Foreshore project the redesigned lighting uses 69 x 150 watt metal halide luninaires, which replace the 119 x 2 x 80 watt mercury vapour luminaires. That equates to a saving of $3,755/annum or 35.9 tonnes of greenhouse gas emissions per annum.

Lighting in shopping areas and carparks is being improved with the installation of cut off white light. White light is the clearest lighting available and this is important for maintaining pedestrian safety. Cut off lighting means that light shining up into the night sky is reduced. Thus the darkness of the night sky is maintained, you can still see the stars!

According to TAMS website

Having not seen the lamps… could they be LED lights?

I read something on a news site a while ago about cities trialling them.

i would go walking at night if it were better lit. i have a morbid fear of twisting my ankle on the dodgy footpaths around my neighbourhood.

Not that women should complain, though. The rapists and murderers have had such hard lives that it’s probably inconsiderate of victims to contemplate defending themselves or even running away. Besides, it’s not the criminals’ fault because they were drunk or on drugs. They just couldn’t help themselves.

If only these vigilante people who dare to voice an objection to lenient sentencing would just STFU and accept that the judiciary don’t care about them and crawl off and die – preferably assisted by some conveniently recently paroled criminal.

You tell me? Depends on who the judiciary decides to release back onto the dark streets and carparks that week while women are out walking or returning to their cars, I suppose.

I often wonder about why we need streetlights. It makes sense along major roads and intersections where there is likely to be traffic after dark, but illuminating the suburbs seems like a waste of electricity to me.

So… pedestrians have to use torches? Flaming brands?

Not everybody drives home. The peasants getting off the bus, the cyclists, and the dog walkers all need to be able to see, too. I walk home through my suburb from the gym every second night, so the streetlights mean I don’t have to walk around with a flashlight in the dark like a horror movie.

Why can’t they use streetlights designed to cast their light where it is wanted, on to the road and back on to the footpath. Lighting up any thing else wastes electricity.

People might want to sleep with their windows and curtains open when it is hot, not close up the room and turn on a fan or airconditioner.

Isnt the whole reason for the orange lights, because your eyes adjust to it easier? Isnt that why tunnels use orange lights? For the same reason that you dont use white light in a photograph developing darkroom, but red or orange lights.

Wouldnt the white lights start to cause more accidents as drivers eyes have a harder time adjusting?

The reason why red and dark orange lights were used in darkrooms was that every other colour light exposed photographic paper and thus ruined the photos. It had nothing to do with your eyes adjusting better.

White light also exposed film – red lights didn’t.

I am glad they’re improving the lighting, as I’ve stumbled and nearly fallen many times while walking down the dark streets at night. It’s actually never occurred to me until just now that I could have taken a torch ….

But as caf has pointed out I do feel safer walking in an area that is better lit.

I think it’s a good move. The lights used to be brighter here in Canberra until recent years. Some inner city suburbs in particular are appalling when you’re trying to locate a street number at night as well.

Streetlights make the streets demonstrably safer, and decently bright ones are an improvement I say (the orange Sodium lights were used because of their low running and maintenance costs).

No, I think it was more for the fog. Those streetlights with the little “hats” that you see in the older suburbs in the south were for the benefit of Stromlo (to direct light downward), but I believe they opted for lower wattage (which is why you can’t see your hand in front of your face in some suburbs at night, despite the streetlamps), rather than orange lights, in order to cut out light pollution.

Pommy Bastard ACT Govt used to paint the side of the light facing your window black on request. They did it for me, years ago when I complained …

Yeah I assumed it was fog too.

I live in Belco and recently found the white lights on my street replaced with orange ones. It was weird, but I guess they got moved to the southside. Mystery solved.

That was my recollection too which has the side benefit of Canberra being a city where the general public can actually look up and see the stars. I guess that is going to be a thing of the past soon.

The old lights were low pressure sodium lamps, chosen mainly because they were very cheap to operate, thanks to long service life and low power consumption, There would have been some benefit for Stromlo too, as the very distinctive Sodium spectrum would have been readily identifiable. (this is long before the days of compact fluorescent lamps). Don’t know what the new ones are.

Sodium lights are horrendous things. There’s a couple of monsters blazing away at HQ JOC every night, and I cannot fathom the need for them. They shine for kms, casting their light on everything in their path.

Orange lights cut through fog much better.

Street lights in Canberra! Whatever next? Footpaths?

I understood that to be the reason why the Europeans used orange headlights.

No idea about the reasoning, and it doesn’t effect me much because I live on a battleaxe block, but I’m on your side anyway, PB.

I’ve always wondered why we want street lights at all. Has the moon ceased to shine? Once a month (I’m a slow learner) when walking from our carport to our house, I have to look up to find out where the light’s coming from (thinking there’s a searchlight beaming down on me from above) only to find it’s just the full moon! Street lights could at least be turned off for the weeks when the moon is full.

I have a vague recollection that street lights were popularised when Jack the Ripper was out and about in London, but I’m not sure they’re making the streets any safer in the 21st century, because there are lights everywhere anyway now.

Su8rely they can’t be ‘greener’, because apart from the energy consumption (which is possibly lower (though this is unlikely)) they also create havoc for wildlife, by changing ecosystems.

Regardless of whether lights are necessary, warranted, or otherwise, I do highly recommend window shutters, though. We’ve had them for a year or so and apart from keeping out street lights, they’re great insulators, and they make it possible to watch television in daytime without the pesky sun becoming a problem.

I think it’s great if Canberra’s finally getting decent street lighting.
