Bad news that the intersection of Martin Luther King Jr. Drive and Peactree Street at downtown Atlanta, GA, USA has been switched from incandescent lights to countdown LED pedestrain traffic signal lights this afternoon (2013-8-22)!
Thats been happening here for a long time now. All our ped signals are LED but about 80% of them have timers. The other 20% are older converted Incandescents where the bottom lense for the walk is disconnected and the top shares the hand and walk signal.
were the incandescent heads polycarbonate? The idea of polycarbonate incandescent signals never sat well with me. With LEDs it's alright though since the LEDs run far cooler. i bet suspended poly heads rock around a lot in the wind too lol.
Was it a full replacement or did they retrofit the light. Over here York Region had LED for 10 years now.
The poly incandescent lights were ok but the lenses tended to brown and crack if the signal stayed the same for too long. That's probably why I preferred glass lenses over poly lenses.
Update: I recently discovered that they replaced with 12-12-12 Dialight LEDS at the same intersection
