Photoelectric Streetlight Control Strictly For NYC

Wed Oct 02, 2013 4:13 am

Hello Everyone, I'm sure I'm in the right forum, somewhat, but I was looking around, just surfing the web, and noticed that a company called Ripley manufactures a Photoelectric Outdoor Lighting Control specifically for use by the FAA.
I figure it makes sense, since these may be used near the bright lights of aircraft, and you don't want the lights shutting off, etc.

But then, I came across THIS
http://www.ripleylightingcontrols.co...ist-lock-photocontrols/nycity.html
and now I have to ask, why does a company manufacture a photocontrol strictly for use by a certain CITY.

There isn't a special one for Chicago, Los Angeles, Washington D.C., Miami, Orlando, Houston, or any other major city for that matter, but New York City, or more specifically the NY DOT uses this special, specific model, that is so specific to NYC that it even has NYC in the model number (6390-NYC).

Why does New York City (I assume all of the boroughs) need a special model photoelectric control for their streetlights? I'm kind of dumbfounded by this, and would assume if NYC needs a special model, why not Los Angeles, or Chicago?

Any help (especially those in the NYC area, or ConEdison employees) would be greatly appreciated.

Thanks
Alright Alright Alright!

I have no idea what the case is here but I have seen similar things when there is a large installation that can't handle an updated model of part.
Don’t repeat earlier generations mistakes. Learn history for a better future.

The only thing I see different than a standard model is the 45 second delay to turn off vs 3-5 second for a standard unit.
It is a 120/208/240/277vac device which is a basic unit (one size fits all voltages)

The delay is the only thing I see, maybe the city was having inadvertent lighting shutdowns due to emergency vehicle or other sources of inadvertent light reaching the photo-cell for more than the 3-5 seconds on a standard unit.

Well for a long time there were "CA Emissions" cars produced and this could be similar. Anyone could get het CA emission vehicles but they were only identified that way.

Looking at the pick, NY may have simply requested the color, a sealed unit, and a longer delay and it became the "NYC".

Well, it also features an Omnidirectional photocell, as opposed to the normal "NORTH" Oriented photocell. Meaning, the photocell itself faces upward.

I also noticed that apparently ONE company manufactures these, and that is Ripley Photocontrols. I thought Fisher Pierce manufactured an FAA model at one point, but as of now, Ripley is the only one certified by the NY DOT to manufacture this particular model.

I can only assume they offered the cheapest bid on the contract?
