Now, the upper lamp uses a linear incandescent R7S bulb (230W on a dimmer). This has just blown, so I thought I'd take the opportunity to swap in an LED replacement (https://www.ledhut.co.uk/6-5-watt-halogen-r7s.html ) for economy reasons. Unfortunately though, the dimmers in the lamp are evidently not compatible, and it doesn't work.
I've dismantled the switch unit and examined the dimmer switch inside - it's this model (Hopestar LD-901): http://tinyurl.com/h5so69z (or http://www.dg-hopestar.com/En/ProductView.asp?ID8 ) - clearly not LED-compatible. So, am wondering whether there's any mileage in modifying my lamp somehow to accept an LED? I can see "LD-600D" on the far right of the Hopestar link, but can't find anything else about it. Wouldn't mind rewiring my lamp to a suitable flex-based switch if one was available?
Any thoughts welcome!
