Hi,

we have one of those floor standing lamps from Ikea which have an uplighter
(150W screw in bulb) and a reading lamp.

All worked via a foot switch with a slider (rheostat?) for the uplighter and
an on/off switch for the reading lamp.

The uplighter isn't working - hasn't been for some time as I thought it was
the bulb and they don't sell them apart from in Ikea.

I now have a new Ikea bulb, but have also checked the old one in another
Ikea uplighter and it works.

I have cleaned up the contacts with (dry) wet&dry so they are shiny.

I have checked with my little analogue multi-meter and I am getting about
240 volts to the contacts in the bulb holder.

As far as I can tell, the bulb is touching both contacts (bent them out, the
bulb pushed them back).

So all I can think of is that the rheostat is knackered - putting out 240V
but at such low power that it won't light the bulb.

As the switch is a sealed unit I can't get at the innards.

Any suggestions about what to do next (apart from just use the reading
light)?

TIA

Dave R
