I have been fitting some of the latest 7w Phillips dimmable LED GU10 fitting bulbs around my house, they are by far & away the most powerful LED replacement bulbs I have come across http://cgi.ebay.co.uk/PHILIPS-DIMMABLE- ... 3a62f571a2
I also see that Phillips sell a 4w 12v bulb with built in fan http://www.downlightsdirect.co.uk/Lamps ... _2653.html
