Ha ha... Super off topic, but last year we moved back to Japan and I had to buy all new light fixtures. I decided to go with these new LED panels. I'm trying to remember the details, but I bought 3 panels each 5,600 lumens for about $100 US each. Even now I have a hard time believing that, so I just did a quick price check online and they are still about the same price. Not only that, but IIRC they get over 120 lumens per watt, are colour adjustable, and have a remote control. It just seems too good to be true. I've only ever seen these lights in Japan, which is really a shame because they are amazing. (of course they are about a meter in diameter which wouldn't suit most western homes...)

Slightly more on topic, it's the thing in my home that most makes me feel like I'm living in the future :-)
