Halogen lamp protective shield - recommendations
 

Hi,

Got a floor-standing decorative lamp with a couple of halogen bulbs on
it. Each of the bulbs is (or was rather) enclosed in a frosted glass
tube as a protective shield, with a further decorative piece of frosted
glass as a shade.

One of the bulbs exploded quite nastily last year, shattering the
protective shield it was enclosed in. I'd like to use the lamp again,
but at the same time I'd like to put some kind of shield back around the
bulb - the explosion was pretty nasty, and I hate to think where the
glass would have got to without the shield.

Lamp shop has been completely unable to get a shield from the lamp
manufacturer. No surprise there, as it must be months and months old!

The shield is essentially a cylindrical glass tube 60mm long with an
internal diameter of 25mm and a wall thickness a smidgen under 2mm.
There's a hole near one of the ends for a fixing screw. Clear glass is
fine - I'm not bothered about the frosting. Simple enough, but it seems
pieces of glass tubing are hard to come by these days.

Does anyone know where it might be possible to get hold of something
like this in the UK ? The internal diameter is the important bit as I
can get the local glass shop to do any necessary cutting and drilling.

Failing that, is there any sort of heat-resistant clear plastic tubing
which could be up to the job which anyone knows about ?

Thanks for any info,

Try a scientific glassblower. They invariably build equipment such as
vacuum systems from pyrex tubing, often up to quite large sizes.
Scientific equipment suppliers may be able to help, but will only supply
in full lengths. If you hasve a Tech College or University with a
Chemistry Department locally, their glassblowers may be able to help you
- get them to cut it to length as it is not easy with large diameter tube.
