DX mercury vapor— colour?

<< < (2/2)

Hi bryantm3,

I haven't response your message for a while, but I think you are right that they refitted with HID at North Spring MARTA Station there.  I did noticed the failure where some of the light has lost the salt emission and started get dimmed.

It's not like the clear Mercury Vapor bulbs that they originally install that last almost forever here :(

Mike:
I saw your pic. In the pic, those are newer (1997-present) GE M-400s. If the lamp itself shines white with a hint of yellow and/or pink then it's a /DX lamp.
