we found the exhibition quite informative.
looks like the future is LED, LED and more LED, lets hope they can sort out the problems of heat management, drivers not lasting the same time as the arrays, light drop off over the lifetime of the array. over driving the LED arrays and the Power factor issues that will stress the neutral when everyone has this lighting.
re the last issue, the power companies are getting worried about it :(
