Street lighting

About two weeks ago, I encountered a fellow changing street light bulbs inside the globes of the stanchion lights in our neighborhood.  His truck carried the name of a private contractor, presumably hired by the Town of Hempstead.  The pink-orange sodium vapor lamps were replaced by LED lamps inside the same globes.

Because these are enclosed, I am unable to determine what each bulb looks like.  I suspect they resemble the one in this link, as it has a screw base socket. Also, the new lights appear concentrated in a bulb, unlike the LEDs that the Town of Hempstead has affixed to utility poles.

The photos below show a variety of street lights in and around Seaford. Clicking on a photo will enlarge it.

Of the new LED street lighting around Seaford, the type in the above two photos seems to prevail. There are five LED bulbs in an X formation, plus a bar of 8 buttons or smaller lights, the purpose of which I don't know.  On Oakland Avenue, this type does not illumine the width of the street.

Maybe six or seven years ago, the Town of Hempstead installed these decorative "bishop's crook" lamps along five or six blocks of Merrick Road.  The other night, some glowed a pinkish-orange, suggesting that the lights were high-pressure sodium vapor lamps.  I'm not too sure whether the whitish lights were mercury vapor or LEDs.   A 2009 article in the New York Daily News priced similar lamp posts at $10,000.

It's somewhat difficult to see that the above Seaford Avenue lamp has twice the LED's than the insufficient Oakland Avenue lamp in the previous photo.  Each position on the X has two adjacent bulbs.

I am fairly certain that the towns supply street lighting along Sunrise Highway and Merrick Road, resulting in a change of illumination for eastbound drivers when they pass over the town line at Tackapausha Park, the creek being the division existing for 200 years or more.  From about 1985 until 2015 something then shocked the eastbound motorist: traffic signals displaying yellow in Massapequa (Town of Oyster Bay) were the same color as the street lights!  With the recent introduction of brilliant white LED street lights, it is again possible to see all three aspects of signals.

One old sodium vapor bulb was left on Saddle Path, Seaford, surrounded by new LED lights shining white.
