kairichter.com. (link updated 1 april 08) thermo-flask lamps, are they hot or not?
he writes, "i wanted to have a kitchen light which transports something of the context. it works also on the table in your office or in your living room. all you need is a lampshade, lamp holder, a cable, a cable-switch and a bulb. to remove the glass-volume from the flask, you just have to unscrew the bottom of the body in left direction, then you can pull the glass-volume out. that's it."
unfortunately, ikea doesn't sell this flask anymore.
