Agree with Kramer............. I've seen these on ebay before - maybe folk involved in theatre and stage business pick them up there - alternaive would be to check "Variety" or similar publications to see if they carry ads for that kind of stuff - maybe check around stage lighting hire companies......
AFAIK, the bulb life on that type of PJ isn't great, and they consume gobs of electricity, but I'd say it'd make a deadly rear-projection set up - plenty bright for day time/ambient light, CR would be pants, though....
