I have discovered that
1. LED bulbs, particularly in those recessed ceiling fittings soon fail. My theory is that they overheat. Nowhere near as hot as the halogen bulbs but the confined space in which the ceiling fittings sit gets warm enough to be higher than the LEDs comfort zone.
2. If you want to really light up a room you do not want those pointy ceiling spotlights. You want a large surface mounted diffuser - the sort of thing you nowadays find in shops and offices.
3. Beware of cheap LED bulbs and fittings on EBay - and presumably elsewhere. My theory here is that LED makers get rid of failed bulbs and fittings to rogues who advertise them on EBay at near give-away prices. Unsurprisingly they just do not work or are dangerous, or both. The buyer is likely to be phylosophical about it and put it down to life's rich pattern. Not worth the hassle of returning the item, little lost, just learn and move on.
That last one has its limits though. I bought, in good faith, a square shaped LED fitting for the utility room. I wired it up to a temporary supply and nothing lit up. I got out my trusty mains voltage tool. Very handy - lights up and beeps when it finds mains voltage without being in touch with bare wires. Useful when drilling walls and fault finding.
Take a look at this:

On the right of the picture is my trusty mains voltage tester resting on the metal backing plate of the light fitting, glowing red and beeping away merrily. No LEDs are lit but the whole fitting is live.
I have of course, raised the matter through the EBay system for these things - aimed mainly at getting recourse or compensation from the seller. Money back and such.
This though is something potentially deadly. I shall let you know what happens.
