Can anyone tell me which energy efficient bulbs would be suitable for the Superflux SD100 downlights? I have tried 2 brands(Philips & Edapt) but neither fit. While they seem to screw in fine, the ballast(?) where the screw joins the bulb is to fat preventing the bulb screwing all the way.
Not sure if that made sense. But if anyone else is using these lights can you tell me the bulbs you are using.
