Yes I have one dimmable GU10 LED bulb,
the centre bulb is a colour changing dimmable bulb, and the outer bulbs simple GU10 LED's and it has a smart relay so I can select centre or outer or both. It is because we want loads of light on the landing at times, but also a dim light so as not to wake people switching on light, and the colour changing does look nice, and one would have a problem getting them all to change together.
But the dangling bits spread the light and over the stairs loads of room, this would not work in most kitchens. One needs a high ceiling for the light to spread out
my son used down lights, GU10 in the kitchen I seem to remember around 14 in that section, so it uses more power than the fluorescent it replaced, may look better, but then the bulbs started to fail, getting the steps in to reach them is not funny, I could reach the fluorescent with a step up, just two steps, as to why they failed not sure, he does not have surge protection in the consumer unit, but could also be a faulty batch.
I have a draw full of bulbs from the tungsten era, when every other week we changed a bulb, since moving into this house 5 years ago, average bulb failure is down to around one a year, I do have a SPD in fact two, as two consumer units. However the sizing of bulbs is not easy, last house we swapped the single 100 watt pendants in living room twice, once for three bulbs which was ample with 6 x 40 watt, but would often use 60 watt, then a five bulb version, and we went for Philips golf bulbs at 8 watt, compact fluorescent lamps, same in dinning room but three bulb version, they reminded me of toc H candles. Told would last years, but within the year most had been changed, to a different make, half the price and brighter, but I got some 1.8 watt LED candle bulbs from Lidi, this is 10 years ago, was to go in table lamp, but we had yet more E14 bulbs fail and went in living room, impressed then got 3 watt versions however rather misleading room looked bright, but not enough light to read with, maybe my age, so mothers house also two chandeliers but smaller room got the 3 watt and we went to 5 watt, so we had gone from 200 watt tungsten to 50 watt LED. Charts say 36 watt LED = 200 watt tungsten, but not found that to be true.
Living room in this house central chandelier 8 x 6 watt, but also cabinet lights 60 watt dimmable, and uplighters and spot light reading lamps as standard lamps.
And kitchen is the same, four GU10 lamps not nearly enough, as pods so can aim at where required, but counter lights I know one side is 22 watt dimmable and actually colour changing although don't really need that, as a strip light stapled to under the cupboard with cable cleats under the surround so not seen just the light.
But kitchen is a work room, so can't really have too much light.
