LED light bulbs hitting the market

Could LED light bulbs finally be coming of age? From Alok Jha in the Guardian:

This month, Philips unveiled its new range of LED bulbs. I was sceptical that they'd be any better than the several I had tried already but, well, something has definitely changed in this technology. The 3W Econic spotlight is a direct replacement for the ubiquitous 35W halogen bulb and claims to have the same light output. When I tried it out, I found that Philips wasn't exaggerating. This is brighter than any other LED I've come across. Putting two in our small shower room, after a while I forgot that the bulbs were not halogens.
