What's wrong with using teflon tape?  I've been using it for 
several years with no problems and gas-tight seals that I can undo 
easily (with a wrench) when the time comes.

Several problems.  These lights are strongest (by far) in the

 They produce a lot more heat than they do light, and they are 
expensive to run.  Other than that, they're just great ;-)
