Here's a shot of a GE GT-X red LED installed in the red section of my Econolite 12-8-8. This LED module replaces the existing red lens and reflector assembly.
I think you misunderstood me. they're just like these but instead of having blank leads, there was a plug with a medium base socket. yuo screwed in the socket piece then installed the LED module (removing the lens) and then you plug in the module to the socket peice. It's a faster retrofit and allows a quicket return to incandescent like Rick Shields said in one of his pics of what I'm referring to.
I know what you mean, but those aren't as good since the LEDs can't be placed as deep into the housing as these and so either have to be pixelated or dimmer than the ones with the deep body.
This is a GT-X module. They are dimmable and can store diagnostic information. Right now these features are only extracted by GE. GT-X units use masks that go behind the outer lens to make it an arrow, or other indication. They only use 4 or 5 LEDs inside.
GT-1 is the previous design that had a coarser pattern and no large GE logo on the back. They also made a seperate arrow version that used a very thin profile with standard rows of LEDs in front of a diffusing lens. I have these in my Flashing Yellow Arrow signal.
The profile is deep because with minimal high-powered LEDs you need a distance between the LED and fresnel lenses to spread the light evenly.
LED fixtures with edison bases are still being made by Electro-Tech and Cooper but they have fallen out of favor. They were an early way to retrofit LEDs into existing incandescent heads in the late 90s and 2000s and used about 600 standard 5mm LEDs.
Ahh thanks I didn't know that the GT-1 was replaced with a newer model already. I just looked through some of the specs and it looks like they have some pretty interesting features too.
Update: I got a matching 8" green GT-X module for this signal so only the amber is still incandescent. This same configuration is used in a lot of older Toronto signals.

I can take some pics of the new module.
