I'm looking at installing some spotlights in my kitchen. I have a set of 3 in another part of the house which have E27 bases fitted with R80 reflector bulbs. The bulbs are rated at 10.5 watts and 800 lumens.
Most of the spotlights I've seen online are of the GU10 variety. They are rated between 4-6 watts and produce only around half or even as little as a quarter of the lumens of the R80 bulbs.
Is that a limitation of the technology used in the GU10 style bulbs and why are there so few spotlights available with E27 type bases?

There are lots of LED E27 R80 bulbs on the market some as big as 25, 27W, maybe more. There are also all kinds of other fixtures that use different kinds of bulbs that provide lots of light.
Why don't you want to use those for your kitchen? Why are you specifically looking for very bright GU10s?
There are 7 and 8W GU10 spots, and bigger GU10 corn bulbs. The main reason there are no 100W equivalent GU10 spots is that there are no 100W GU10 halogens. So there is no replacement market, and hence more risk in making and selling them.
Sure, people do make and sell LED bulbs that are not replacements for anything, they are entirely new in what they do. But to make and sell 10W+ LED GU10 bare bulbs in the hope people will use them for anything other than retrofitting would be a bad bet, and people would be unlikely to retrofit bulbs that are double the brightness because, IMO, these bulbs are very harsh to begin with.
