Anyone ever had 2 same MH bulbs that gives out different colors?

I have 2 XM bulbs same age same brand but one is slightly dimmer/yellower. THey're both 10k running off the same kind of ballast. I've proved that it's not the ballast cause I swap ballast. Can it be bulb or can it be reflectors? (Same pendant too btw.) AM Ocean Lights. However, I do noticed that the yellow/dimmer side reflector seems a little more dull looking. I asked others and they say they look the same but something is telling me one is duller. maybe I'm tripping.

Perhaps a defective bulb? There was a thread a few months ago in the lighting forum about the people who ordered the aquarium traders metal halide fixtures had 2 of the same bulb but the colors were VERY different on one side of the tank than the other.
I'm sure if you can get through to the search, or check the lighting forum, you'll find the thread.
So i'd say, its a good possibility they could be different colors.

I know those jebo/oddyssey bulbs have this problem. But XM? that's crazy.... well it's time for new bulbs anyways. I just toss these out for spare, I broke the ceramic around the contact. Still works but it's that feeling of broken bulbs. I think I'm gonna attack the 10k ushio
