Following on from the thread about Lathe Lights & the Anglepoise copy. I have a many year old genuine Anglepoise which was originally designed to take either 40W or 60W, can't remember which, incandescent lamps.
At the moment I have a 9W LED installed which is somewhat heavier than the incandescents such that the springs are just that bit too weak to hold it in the set position and the light slowly but surely drifts downwards.

Cut the loop off the end of the spring (s), then bend the first wind of the coil to make a new loop for your now shorter spring, repeat until you get the right balance.

On some models of the older genuine Anglepoise lamps the springs are adjustable. On the one I have, the springs terminate at one end in a chrome plated machined part that 'screws' into the end of the spring and is tapped through for the cross drilled stud that hooks onto the peg.
Best to check before you start modifying the original springs.
PS I have found that some of the latest LED lamps are significantly lighter than the earlier examples

The small (12w) spiral-design CFL bulbs balance OK in original Anglepoise lamps.

We had an IKEA clone Anglepoise with LED bulb, but SWMBO evicted it from the living room. I pinched it for the workshop, but when it is switched on the RFI from the bulb kills the radio. Is this usual for IKEA bulbs?

Not in my experience

Ok folks, thanks for those comments.
I think the first idea might be to cart the lamp down to my nearest lighting retailer and try some other bulbs to see what happens. If I can find one that works ok, weight wise that is, then that might be the way to go. Otherwise I'll have to see about getting a set of spare springs and modifying those - I'm very relectant to mangle the originals in case I reduce the lamp to scrap.

Peter, would be much easier to source some 60w GLS lamps.

I bought three 4.5 volt LED lamps from Super Cheap Auto ($NZ 6), these are a spherical shape about 80 mm diameter mounted on a gimbal type mounting, I removed the magnet in the base and taped the resulting hole 3/8 UNF. Two of them I mounted on Angle Poise lamp brackets, the other I mounted on a Goose Neck lamp stand. I removed the batteries and powered them with 4.5 V wall warts, one angle poise mounted one is over the Box-Ford A at the Menz Shed, the other two are over lathes at home, now I need LED lighting on the milling machine.

A helper spring or rubber band down the middle of the existing spring might do.
The problem I have with this style is the way the back end swings round and hits things. My best arrangement is a lampholder and reflector in a rigid rod going horizontal to the vertical rod of a standard chemistry lab retort stand - no backswing when I turn it 180 degrees onto the drill.

You can get get LED bulbs that are practically identical to the old incandescent bulbs in weight and looks, like these, which in warm white is not tiring on the eyes as the whiter varieties can be.

Keep it for a few more years. You will find that after a while, you will tend to drift down with it as the day goes on.
