Brightest GU10 LED - or maybe something else ?

[Viktor]

That's fine, that wouldn't bother me at all, I just need more light.

As others have said, there are nowhere near enough downlights for that space. Any GU10 you fit will still be disappointing with your requirements and expectations for an ultra bright room.
You should add more downlights or change the lighting layout completely.

 

[telectrix]

you could fit 20watt downlighters, but you'd need larger holes. approx 5" diameter.

You might consider LED panels that can be ceiling mounted and give the kind of lumens you are looking for. There is also a mini highbay light that is very bright.

Is this a rented property?

 

[Viktor]

Yes, I'm renting it, otherwise I'd have a completely different lighting, I'm not keen about spotlights at all.

Then surface mounted LED panels might do the job (as Vortigern says), and fairly easy to re-instate the original lights if required, with minimal re-decoration. But get an electrician in to do the job properly. Maybe talk to your landlord about the problem.

......... 6000k colour is a blueish daylight and doesn’t suit a lot of places.

Unless you want to highlight your blue blinds when they are shut !

( long fluorescent tubes may not have been cool - but suited many larger rooms )

I've just re-read the OP's #9 about room dimensions. I'll get my coat

Yes. Six GU10 downlights in a 13m long room is pretty useless.

I’d do what @telectrix suggested and stick in some commercial larger cut out 24-30watt in the light colour of your choice.

Just to second getting some wider beam LEDs. I've got 4x 110 degree 400lm GU10s that illuminate my living room, which is about 5m x 4m. Brighter lights aren't worth anything if they're only pointing at a 1m spot on the floor

 

[The Ghost]

I think the problem with cutting larger holes is the Landlord may charge megabucks to re-instate the original lighting (bang goes your deposit). At least with surface mounted LED panels as @HandySparks has observed they are easy to remove/re-instate. You could leave the spots as is and just have the panels switch on.

You said saving electricity is not your concern . Swap them to 12v 50w halogen . that should give you about 800 - 1000 lumen per fitting .

20W Gu10 LED, might even last a few minutes, but cheap enough, though the specs are dubious for that size lamp!
