Just rebuilt a mid-'60s bog-standard Anglepoise lamp

Fit a 12V lamp into a BC adapter in the lampholder and use an external
transformer so the Anglepoise is only running low voltage.

Certainly avoids 240V on the lamp, but portability...

Also, I'm 'tuning' it to take a CFL.

If by tuning you mean adjusting the counterbalance springs then fair
enough. Without such adjustment, a CFL will be far too heavy and the
lamp end will droop.

Err, I'm sat looking at an Anglepoise lamp which has a 5W CFL in it. No
adjustment to the springs required.


Surprised to read that Hugh. Anglepoise lamps I have seem to be so
critically balanced that a tap on the lamp shade will set it moving. The
springs give a fairly well damped oscillation and it soon comes to rest
at the original position.

I assume that a 5w CFL will be quite a bit heavier than a 'proper' bulb
and hence my comment.
What happens to your lamp if you take the bulb out? Mine shoot skywards.
