Re: the used lamps being treated as hazmat, I used to work at a university where they did that. The truck would come every 2 weeks to pick up the tubes/HID lamps from all over the campus. Then compact them right where it was and leave mercury running out the back [Linked Image].

As for the scepticism, I just wish more places were like that so people would tend to believe it more often. Telephone company buildings are often a good place to see good wiring practices, of course they never had the 'oh it works so it must be ok' attitude that prevails in many places [Linked Image]
