TIR 80 vs 120 Lens

[nighthawk26]

Hi Guys. I'm looking to by 3 used radions from someone, and I'm wanting to know if there is a way to tell from looking at the lenses if they are the standard or wide angle TIR version. Also, is there a way to know if its a G1 with added TIR lenses, or if it's an original G2? I assume the build date would be one indicator, but anything else? And if it is the build date, what dates is the typical crossover from G1 to G2?

Thanks

Wide angle optic is listed on the edge of the lens. I don't recall if you can see it without taking the cover of the radion off. You can see it on this image

PERFECT. Thank you.

Now is there a way to know G1 vs G2 units other than manufacture date? And if that's it, what dates am I looking for?

Thanks again.

I don't recall seeing model numbers on the light. I just see manufacturing dates and serial numbers. I guess you can search online to figure out when each version came out and use those dates as a guide. I know that you can get the model information through the reef link web interface. The model appears on the devices page.
