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.
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.
