scottr: Suspect with all the light going down as opposed to everywhere else that a lower amount of lumens are OK.
Have come across these, 15w at 120 lumens, dimmable, and will fit the current downlight hole without any adapters or re-cutting of the whole.
Only 22.90 so I might grab one, give it a blast, and if all goes well potentially grab a few more. Anyone come across these or this company in their travels?
@scottr Check what type of dimmer you need. As older dimmers tend to be leading edge. While LEDs and other lights with drivers tend to require trailing edge dimmers. Also remove the bulbs from the other lights on the dimmer while testing. As having a filament lamp connected to the dimmer helps the dimmer to work better with LEDs.
