Just bought one yesterday.  It works great.  I can adjust it from
near-dark (muy romantico) to near-daylight (nothing beats daylight
in Phoenix...)

I doubt that.  The power is the same, and the light seems not to
be as strong as from a comparably powered standard incandescent.

But you're not going to find many 500W edisonian bulbs.  They
tend to evaporate their filaments.

Check out The Home Depot, if you're in the Southwest.
Hechinger's or Channel might have them, elsewhere.  I got
mine for $29.95, with a white enamel finish.  It sits where
my living room meets the den area.  The LR has a vaulted
ceiling which reflects the light obliquely, making it very
efficient.  The spillage into the den makes it the only
light I need in the apartment, outside the bedroom,
kitchen, and bathroom.

Nah.  They're a lot better than that.  Your ceiling must be dirty.
Mine replaced a 250W bulb I was using in a table lamp, and beat
its luminescent butt.

They do provide a little direct lighting, too, through a heavily
frosted plate in the base of the reflector bowl.  The bowl is
really just a shade; the real reflector is inside it, closer to
the bulb.

Assembly is a pain; the cord runs through the tube, which
comes in three peices, and there are two more in the base
and bowl.  You have to rotate things backwards a few turns
before screwing them together, to keep from binding the
cord, which at this power could cause hot-spots.

Almost anywhere, it seems.  These things look set to take
over the home-lighting industry.  They've already wiped out
both incandescents and fluorescents in the desktop lighting
niche.
