Re: Ballast in halogen lamps (sometimes)
Hmm, maybe I can locate the 'dimmed live' wire going to the top lamp fitting and wrap some turns of a pickup loop around it to see if I can see which part of the half-cycle is being knocked out, the leading part or the trailing part. One thing for sure, there is no shortage of current whizzing back and forth along the wires to the lamp.
Being a standalone floor lamp, this particular unit does have the neutral available within the unit so the dimmer circuit, if required, could have full time, full fat mains and only needs to act on the downstream feed to the bulb fitting. It doesn't necessarily have to be an inline (series) dimmer like the ones used in wall switches.
