Liftwaverf dimmer for recessed spotlights

[Crossway62]

Hi, hoping for some advice please
The house we've moved in to already has recessed spotlights in the bedroom, 8 lights on a dimmer. The bulbs currently in are Iviti gu10 6wd w cob Fu. We've been able to put a liftwaverf smart dimmer in the dining room so thought we'd do the same for the bedroom. We've wired up the new switch but when switching to off the lights stay on at low level. I can't see what make the spotlights are as the loft is now boarded. I'm not sure whether the lights are just not suitable or if I need different bulbs? Little electrical knowledge, so any suggestions gratefully received! Thanks

The not switching fully off can be cured by putting a capacitor across the lamps, normally around 4µF some also have a small resistor, called either a load capacitor or a power factor connection capacitor they will remove the problem. However they need mounting some where, and they are too big to fit into many junction boxes or ceiling roses.

I used a Danlers Low Load Capacitor from CEF (0900-6730), Screwfix do Elkay 4µF Power Factor Correction Capacitor (1373G), TLC call it a Glowfix Load Regulator or Danlers Low Load Capacitors for Low Energy Lamps (DN CAPLOAD).
