I'm sure there must be plenty more who use these.
Heavy glass lens, circular fluorescent lamp etc on 2 off 18 inch long

sets
of arms with springs. However much you tighten up the central clamp the
top
arm sags down in use, especially when you rotate the whole lamp or the
angle
of the head.
Place a dense rubber tap washer under the nut of this clamp. Changing

the
angle of the arms is then stiffer but I prefer that, to sagging in use.
Anyone else have any other ideas that retain full functionality.

I have two genuine Terry's Anglepoise lamps, both of which go back many
years. Both of them suffer as you describe occasionally, but I have always
found that re-tightening the Nyloc nuts at the joints, cures mine for
another year or so. I wonder if that's because the 'head' on the lamp

weighs
a lot less than on the magnifier version ? Do radio studios suffer a

similar
problem ? They seem to use exactly the same arm mechanism for presenters'
mics, and I would guess that some of them with spring mounts and baffles,
must be as heavy as the magnifier lamp heads.

Surely audio studios have the springs in either Anglepoise, far reach
suspension, or microphone , local suspension, replaced with bungee which is
naturally damping. The last thing you need attached to a microphone is a
twangy resonant springline. Going by the racket that comes off my Anglepoise
in normal use.


The microphone sits inside a cradle suspended by thin elestic bungees
