My old house had a fluorescent tube in kitchen extension, started with 65 watt fat tube, then 58 watt, and then 22 watt LED, the LED lumen output was half the fluorescent tube, but never really needed 5000 lumens, the 2400 lumens were ample, it was the length of the tube which was required to give the spread of light.
Son bought my old house, and swapped the LED tube for down lights, 14 of them, and the room I admit looks better, and more modern, but no improvement to how well it is lit, around the same, 4 watts each I think, so 56 watts v 22 watts, and quick look at 4 watt GU10 Phillips, and I see lumen stated is 270, so 3780 lumens v 2400 lumens. But the direction is the problem, they are aimed at the floor, my new house kitchen has 4 x GU10 pods which can be aimed, nowhere near good enough, on my to-do list, but aimed at the areas needing light they work, and to make a cup of coffee often say hey google turn on sink, and just use one of the four lamps.
My wife wanted a chandelier for the stairs and landing, I refused to fit it, felt it was stupid, but my son fitted it, and yes looks good,

and I can select outer, inner or all bulbs, so can have it dimmer in the middle of the night, but as far as lighting the area, 25 watt total GU10 or 12 watt BA22d, other end of the landing I have a plug in emergency torch which has a built-in PIR detecting light level and movement, which at night lights as we pass it, as light levels from the chandelier are not high enough.
There are two problems with the down light, one is the direction of the light, and the other is the intensity of the light. How this
can be called MR16 I don't know, as the outer part of the bulb is cooling fins, it also does not have a multi faceted reflector as well as not have a 16/8ths of an inch illuminated area. The spread of light from a MR16 compatible bulb varies a lot, I like my Energiser smart bulbs, but

they are not an efficient way to light the room, but loved to wind up my wife turning the kitchen green for Halloween. I would not entertain any lamp where you can't change the bulb unless being sold off super cheap. I got an outside carriage lamp for £5 which is integral, and it lights the entrance very well, but had to buy a smart socket adaptor to control it, so another £10 where had it used a bulb, the smart bulb is only £5, and it is far easier swapping a failed bulb to swapping a whole lamp.
Shinning a light up to a white ceiling spreads the light far better than the same bulb facing down, so this

works well, why the builders considered a room this size only needed one light I don't know, with a 150 watt BA22d tungsten bulb it was OK, but a 15 watt LED did not light the room, it was like a tocH lamp. So even 6 x 8 = 48 watt LED is not really enough, but it is a lot better.
