I confess that I've not seen a globe with a band as you describe - all the
globes I've come across didn't have any protection and I've not broken one
yet. Just be careful when tightening the screws, they don't need to be
tight on the glass simply supporting under the lip. Remove your band and try
it.

Don't do the screws up tight, ensure the globe is free to move. Being
a fan as well it might then rattle or the screws work loose. Fairly
low possibilty of either provided the fan is properly balanced. There
is probably enough thread on the outside to fit a locking nut.

A little bit of glass fibre stove rope would provide some padding, if you
know where you can scrounge an inch or two?

Would tap washer do it?

I've done exactly the same thing, but without the rubber smell. I wonder if
rubber bands vary somehow?

I think silicone is pretty heat resistant.

What about an O Ring under each screw head? This would allow the glass to
expand.

20W CFLs wouldn't get so hot.

But don't like being in an effectively sealed space, they might not
run as hot as a 60W incandescant but the heat they do produce does
need to get away. The only CFL that we have fail regulary(*) is the
one in the bathroom globe light fitting...

Silicone sealant is often used when refitting an exhaust to a motorbike so
wouldnt worry about it being heat resistant, another matter if you want to
use it in preference to the other ideas posted.

One tip you may do well to avoid the acetic acid based silicone sealants
as these may eat the copper.. try

or

That will be an entirely different silicone. Most can only survive up to
about 220 %C

We had one like it - I think the rubber band was to try to
mitigate the rattling when the fan was in use

Anyway, I think before you use elastic bands, make sure they are in good
condition, and if you can put a layer or f something like castor oil on
them, as they will perish faster without it in my experience. Some of these
lamps have a little trough for an O ring to be used, so you may be able to
obtain those if they are a standard size.
