I have 14 downlighters in the kitchen, two separate circuits of 7
Originally they came with Magaman 7W Cold cathode bulbs but now have 7 Watt LED GU10s
They are so bright that there is no need to have them all on. Far brighter than the Cold Cathode bulbs and, in my view, brighter than the halogens which I have in the bathroom (which will also be getting upgraded to LED soon)
