Philips Master LEDSpot VLE 5.5W LED GU53 MR16 Very Warm White Dimmable 36 Degree - 70823100
These are fine. As described they are very warm, i.e. quite yellow.
Worked with old dimmer but had a step type dimming effect. Resolved with led dimmer, now dims perfectly. Whilst compatible with old transformers, 1 light didn't consistently dim, must have been an issue with the transformer as the bulb works well in another outlet.
