Funny that. I swapped one last week and had no problems in
buying one.

Name any application in which they have an advantage over HID or
sodium. There are none.

Any application which currently uses them, and you need to replace
the lamp!

I have plenty of things at home with obsolete technology in.

Don't you mean obsolescent? ;-)

Quote: Things that are obsolete are out of date or no longer in
general use. Things that are obsolescent are fading from general use
and soon to become obsolete. For example, the Windows XP operating
system (released in 2001) is not obsolete because some people still
use it, but it is obsolescent because it will presumably be falling
out of use in the coming years.

Things that are obsolete are usually not so out of date that they've
been forgotten, however. When obsolete things are forgotten, they
become archaic.

So no, I mean obsolete and in some cases not far from archaic.

In case you had forgotten I was ribbing your choice of word based on the
previous discussion, where you complained because I referred to a
VO-ELCB as obsolete. It seems you now agree with my original use.
