Could they be?

Could they be?

This is at the college I went to originally for horticulture I am likely going to go back for electrical. Anyway the building was built in 2002 and when I went there before I had thought these were metal halide lamps but I believe I was wrong. Could these actually be clear mercury vapors? The camera sure thinks so. The two nearest the camera and the one to the left seems greened out and have a really interesting blue/greenish color that one to the right looked much brighter and was a yellowish green color

My guess is they are probably metal halide that are getting close to EOL, I have seen metal halides take on a MV colour before the end of life

Maybe the metal halide lamps reached EOL and were replaced by mercs. I've seen it happen. Some people are "CCT blind" and/or "CRI blind".

Yeah thats likely too, as some maintenance personnel don't know the difference in lamp type, but that would also damage the mv lamp since the ignitor would be present

Not necessarily. If the system is probe start, and the wattages match, it will work properly. You are right for pulse start systems, though.

I have seen mercury vapor installations in malls that were built in the mid 2000's so it's a possibility. Is that "flower-lamp" in the middle MV?

LEDs = Downgrade 85% of the applications.

Most MH lamps I've seen, reached EOL before all of their halides got deplated, so burning as clear mercury lamps.
I had only few case of mercury only MH lamps here and here

I"m don't speak english well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I hope that LED won't replace all forms of other lighting.
