Coming to a street near you, the lights that keep you awake and could make u ill

[ArMaP]

First of all, I didn't read all the text, the lack of line breaks makes it hard to read, and I stopped when I read that sodium lamps use lithium gas, as that's not true, sodium vapour lamps use sodium (a metal, like lithium) and an inert gas like neon, argon or xenon.

Another thing that's wrong in the text is that LED lights give a light that is too blue and so affects people's sleep by messing with melatonin levels. As anyone that has looked at red LED showing that some appliance is on, LEDs can be made to emit in any colour. For white lamps the method usually used is to have ultraviolet LEDs inside the lamp covered with a phosphorescent material that turns ultraviolet light into visible light, like in fluorescent lamps.

At my home we have been replacing all old incandescence and fluorescent lamps with LED lamps, as they use much less power than incandescence lamps (a 100W incandescence lamp gives as much light as a 70W halogen lamp, a 23W fluorescent lamp and a 15W LED lamp) and (supposedly) last longer.

As for the colour of their light, we have lamps emitting light with colours from 2700K (yellowish white) to 6500K (bluish white, like the one I have in my room and that doesn't affect my sleep )

From what I read of the article, it looks like they chose those lamps without thinking about the colour of their light or about the shape of the light projected from the lamps, as they really look more like projector lamps than lamps for replacing common street lights. A quick look at the site of a Portuguese company that sells LED lamps for all purposes shows me that they have lamps with a light colour of 4000 K, similar to the light of an incandescence lamp and warmer than the light from a mercury vapour lamp (a kind of lamp also used on street lights that has a white light instead of the yellow light from the sodium vapour lamps).

But there are a series of small lights in the thing..not just one large bulb..It maybe that you need to break all the individual lights to knock it out fully depending how the electrical circuits are designed..

Probably, as they are not likely to be connected in series like Christmas lights but in parallel, so if one goes out they do not have to replace the whole head. In fact, each one of those small lights is made up from several LEDs, as the light a LED emits comes from a very small point. I will post a photo that shows what I mean after lunch and after watching the Monaco F1 Grand Prix.

I would guess these are nothing more than high efficiency low amperage LED lighting to conserve power. While it may be right to be paranoid that your government is spying on you, I would think putting up a surveillance network in conjunction with these lights would yield very low amounts on intel in urban areas and I couldn't see the logistical cost of it paying off in any sort of way as there simply is not a lot of terrorist activity or much other anti-government activity happening at peoples homes other than maybe on the PC which they already have covered anyways. From what I have seen the surveillance lights have a dome with a swivel camera in them. Those you might find in commercial areas.

do you have any idea of what that is in the hole ?.. bit big for a ballast no ?

what someone needs to do is crack one of them open , see what type of gubbins is inside

The hole could simply be access point for a mount bolt or something...I agree someone needs to see if they can spot a manufacturing label, name or cross reference the style of light with a supplier and see the specs on the light. The point is regardless of what they put up for a light there would need to be a separate set of wiring ran for the network to link them all to the mainframe. I can't see these being any sort of Bluetooth device.

are you aware you can run a network through the electricity grid of your home ?
what's saying it doesn't work on the main electricity line's too,

spot a manufacturing label

maybe it was under the paint

I have  one unusual surprise..

Many weeks ago I found a large fan that had been left out side  someone house who must have thrown it away...but it was missing a front guard..But I took it home and tried it and it worked fine..

As I was walking down another street on my walk to check the lighting in the area...I came across a Fan Guard and it looked the right size on a skip...I picked it up and took it home and checked it...and it fits ok..

what are the odds of that I wonder ? 

interestingly portentous , what does the fan smell of?

Yes I am aware of networking through the electricity grid but if you really want to get that paranoid just remember that every light in every building could be set up in the same fashion. The need to mic street lights seems to me a complete waste of time considering the amount of terrorists and culprits that hang out under street lights discussing their unlawful plans. How many conversations are you going to hear as cars are zipping by, lawnmowers going, dogs barking etc. They will spend money where it is practical to do so and I just don't believe that is an efficient use of resources unless it is in an area known to have a large amount of criminal activity.

FOCLMAO, , , , , , heh heh heh heh , ,thanky, 

, , as for those lights, this would help

Probably a transformer, and if they have the capability of dimming the lights then it's probably a variable power supply.

[robomont]

Its obamas speach in japan of a higher moral.the idea is to police us into insanity or absolute obediance.
Each light would be just another android.only camouflaged to be a light ,probably powered by solar.

Resistance is futile ,obediance to the state is all that matters.
All run by a computer that cares about you.with base programing done by psychopath mormons at nsa.
Just remember,every pyramid skeam ,eats its young.

I hate to say it but we all see what needs to be done,the matrix must be killed.its gotten out of hand.its become oppressive.it violates all civil history law.

[ArMaP]

Here are two photos showing a small LED light I bought some weeks ago, just to make some tests.

This is supposed to be used to replace the light above the passengers on a car, but in this format it can be used anywhere.

Each small point on that yellowish surface is a LED.


When on (with a low current) we can see the individual LEDs .


PS: if they wanted to add cameras and/or microphones on the light poles they wouldn't need to replace the heads, they just had to put the cameras there. In fact, it would be easier to add a small camera to a larger head than to those smaller (and fragile looking) heads.

Outdoor Lighting: London makes LED street light plans; US and UK projects - LEDs

"Meanwhile, municipalities large and small continue to pursue SSL streetlight upgrades around the globe. The Pascoag Utility District in Burrillville, Rhode Island, for example, became the first entity in the state to test LEDs on 56 streetlights, according to the Providence Journal. The small project has resulted in a $1710 decrease annually in energy costs and $2535 decrease in maintenance costs."

$30.53 per light in savings.

Just how much difference in price are these new LEDs and their old counterparts?

"But the impact of the project could be far greater. In part the success is leading Rhode Island to be the first state to force utilities to allow municipalities to buy energy-efficient streetlights and capitalize on savings. Work in the Rhode Island Public Utilities Commission will allow municipalities to get a lower rate for lower-power fixtures, and an even lower rate when adaptive controls are applied. The action could make the state a leader in LED adoption for roadway lighting."

"The upfront cost of the project will be GBP 8.2 million that will be spent over the next two years. But the Council pointed to a combination of energy savings, safer roads, and reduced light pollution as justification for the expense."


Texas plaza demonstrates uniform outdoor lighting, no spill

"One of the many advantages of LED-based lighting is precise beam control, and that attribute is very important in area-lighting applications such as a recent project completed by US Energy Management in Allen, TX. The Twin Creeks Village shopping plaza underwent a solid-state lighting (SSL) retrofit of its parking lot that has resulted in significant energy savings and - equally important - is delivering much-better-quality lighting. The prior high-pressure sodium (HPS) lighting was replaced by Edge High Output (HO) LED luminaires from Cree...

The property owners at Twin Creeks had asked US Energy to propose a one-for-one retrofit of the existing HPS lighting. That prior lighting design had two 1000W fixtures on each pole at a mounting height of 40 ft. The HPS lighting had delivered an average of 3.9 fc at the parking lot surface. But the owners weren't happy with the lack of uniformity that is apparent in Fig. 1 - a depiction of the prior HPS installation. The HPS lighting yielded bright spots under poles and much lower light levels between poles. Fig. 2 depicts the much more uniform LED lighting."



FIG. 1. The high-pressure sodium (HPS) lighting at the Twin Creeks Village shopping plaza in Allen, TX exhibited hot and dark spots and poor color rendering.



FIG. 2. Cree Edge HO LED luminaires were used to improve the uniformity of lighting in the lot to the property perimeter while minimizing light spill.



FIG. 3. The Edge HO LED luminaire is specifically designed for high-output lighting applications in which 1000W HID fixtures have been commonly used.

imho adaptive and safer streets are code words for spy,as this is simplest way. have android run the whole system,  but i do like the cost thing, and the light polution thing.

The second photo was either altered or not taken in the same conditions as the first, as we can see that the lights in the background are much brighter than on the first photo and the letters on the building at the right look white instead of blue.

who said anything about microphones ? im more interested in them being used to induce hypnogogic states
