The only LED light sources in my house, besides the LEDs on some electronics, is this lamp: http://www.konceptech.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=K&Product_Code=LL3001-MBK http://www.konceptech.com/Merchant2/merchant.mv?Screen=PROD&... And a camping headlight. I consider these two things to be of the coolest things I own. They definitely show off proper LED application. For the camping headlight, which wasn't very cheap, I don't have to worry about disrupting the darkness too much. And the batteries will last forever. For the lamp, same thing. It is a wonderful feeling staying up till 5 in the morning with nothing but you, the lamp, and your work. Nothing but the desk and your work is illuminated, and it is illuminated very pleasantly, which is awesome. So, depending on the application, those negatives are strong positives. I can't imagine the LEDs being used as household lighting.
