Magnetic rapid start ballast
Developed in the mid 1960s, replaced the predominant (at the time) HID light source for streetlighting.

Vintage industrial shoplite.
they're blue but use yellow phosphors to render as either soft, warm, or cool white.

HPS, MH streetlights never really took off here.
I'm guessing those Philips LED lamps, most use a blue LED covered with a yellow phosphor.
Traditional type of traffic light, became less common and was largely replaced with LED in the mid 2000s.

incandescent traffic signal lamps
Runs F40T12s at full power and tends to leak tar if used with 34w lamps for extended periods

I meant full power ballasts...but you're still right!
I'm guessing preheat choke or HX-NPF mercury vapor ballast...

No one has posted recently so...
Is famous for their electric shavers and made some really cool lamps of all types, but I especially like their F40CW florescent lamps.

Phillips............
A company that used to be the best US manufacturer, but now a badge relegated to cheap and low quality lamps and appliances made all over the world for the lowest cost.

Technically you're right but I was thinking Norelco which was the American equivalent of Philips before they bought out Westinghouse...Norelco stands for something like NOrth american Philips lighting and ELectrical COrporation...
I'm guessing Sunbean or GE?
The dark sky people really don't like these lights...

Yup!
Was the predecessor to Philips here in the US in the 70s and is famous for their electric shavers and also made great lighting products, and I have a F40CW made by them...
