Voltron:
Just so you're aware, those bulbs may or may not be hazardous waste (more than likely, they are not). You need to run a test known in my industry as a TCLP (Toxicity Characteristic Leaching Procedure) for Mercury. If it passes, keep the results in the file and into the dumpster they go. Without testing, by default, they are assumed as hazardous, and you're a waste generator.
The test isn't cheap, maybe $200-300, but if you're paying to dispose of bulbs, it might save some cash, and you aren't on the state's list of generators.
We've been doing this at all our facilities, and so far, all bulbs passed. Save several thousand bucks during relamps. I'm not speaking out of place...this is what I normally do for a "living".
