My father found a green LED traffic light insert thing in the intersection in front of his workplace. The lights at the intersection were all there, so it must have fallen off of a truck or work vehicle!
Made by LEOTEK, which is a subsidiary of LiteOn.
It's rated for 80 to 135VAC, 60Hz, 6.7W/7.1VA (So the PF is not quite 1).
Model number: TSL-12G-LX-IL6-A1-P3
(I attached the datasheet, which was easy to find regardless.)
MFG date: AUG 2014
Intensity rating: 475cd (min) @ 500nm (dominant wavelength)
Hooked up a cord, plugged it in, and it works! Strange!
The lamp:
Lit up:

The LED itself, next to a penny:
(It's outside of the pic, but there is an NTC thermistor on the PCB, presumably for overtemp protection. The lamp unit doesn't really get too warm to begin with, but it might be hotter inside because the plastic case doesn't transfer heat very well. Plus, in the summer it gets hot outside.)

Power supply (bottom):
Some of the power supply components:
470uF 35V Nippon Chemi-Con KY series (105C) capacitor,
(small cap is 22uF 50V TAICON, 105C)
L6562A PFC controller,
2904 dual OP-AMP,
B5100C 100V 5A Schottky diode,
DF06S Full-wave bridge rect. 600V 1A,
STP4NK60ZFP 600V 1.7Ω 4A N-channel MOSFET,
STF2HNK60Z 600V 4.4Ω 2A N-channel MOSFET,
02N6A 600V 8.5Ω 1.4A N-channel MOSFET,
3.15A 250V fuse
Note that the N and L wires are reversed! Not that it matters, since the whole lamp module is isolated.

P.S. I forgot to take a pic of the inside lens, it's like a fresnel lens. I'll take a pic tomorrow because it is dark outside now.
