Loose sounding piece rattling at bottom of Sunmaster HPS bulb?

Hello, I got a replacement Sunmaster 600W HPS bulb from HTGSupply and the base seems to have something rattling around in there. I can hear it but cant see it. My other bulb does not do this but I found a post from 2007 with someone asking the same thing. It runs good so far and I emailed for a replacement. I am wondering if it is a bad idea to use it until I get another replacement in about a week?

its usually the metal ring going around the glass nub inside. doesnt seem to effect it. you would think they would address this, but its so common they obv. dont care.

Would this specifically come from inside the screw housing? It sounds like something it literally loose and rattling around when I turn or shake it. I can figure out what. I plugged in the bulb and ran it for 3 hours without any issues but it is a bit nerve wrecking.

the metal ring im talking about is at the top of the bulb, if its coming from the screw base, the worst that would happen is the bulb burns out.
