(The one exception here is the GE Genura R80, which
at 23W produces more light than a 100W flood lamp, but it uses
a significantly different technology from standard CFLs.)

Of the several we have, one in particular is squintingly bright to look at
which is a Mazda 6L electronic - it has 3 folded tubes or "6 legs" (6L?)
and gets brighter after a few minutes. I have looked around casually for
more but
have not seen them again...
