Efficacy (luminous efficiency) is getting there...

At last, a production LED that approaches the efficacy of good fluorescents (100 lumens per watt).

I saw this announced at the Lightfair tradeshow this week. I expect to post more on other subjects later. Now admittedly, this doesn't include power loss in the power supply (ballast), but we're getting there. I'll be interested in how the light radiates and how much they cost as well, because that will make or break it in the long term.
