My son fitted down lights in his very small kitchen 7W LED x 5, I had to use a torch to read the pressure on his boiler, I have 10 x 3W bulbs in a living room which must be at least 4 times the area of his kitchen and no problem seeing what you are doing. The problem is the area of light emitting bit, put a 6 inch pearl defuse glass under the spot light and then they work, or use more of them, at 2" anything over 3W is wasted so my kitchen as a fluorescent fitting with a 28W LED tube which gives out 2800 lumen, a typical 3W GU10 is 250 lumen so you need 10 to 12 to give same output, that is a lot of work installing 10 light fittings, it may look better than the LED tube, but even the LED tube is well down from the original 65W tube, the new 58W tube with a HF ballast gives around 5200 lumen if you want to match that it's 20 little spot lights, maybe you could arrange them to emulate the great bear or some other as shown with a planetarium, it would be novel and quite a talking point.
You have to remember size matters.
