Apparently it will be OK with a trailing-edge dimmer, so say the instructions with the new LED replacement bulb. Do I know whether the dimmer circuit is leading edge or trailing edge? Of course not. I bought dimmable because my Dad does occasionally turn it down to, oh, only 200W or so, so I do ideally need that feature to work.

The lamp is I would say about 15 years old - apologies but I thought I had posted this in 'Modern Technology' since it concerns a relatively new lamp and a LED replacement.
