If you're looking for a light to go with the Buldang couch/chair/thing, you won't go far wrong if you buy a Boalum. I'm sorry, I didn't mean light, I meant "luminaire," which is what this piece is called. (Luminaire means, among other things, "light fixture," so this is a somewhat fine distinction in my book.)
The Boalum has a flexible, tubular body of opal white plastic that diffuses the light. Or rather lights, as this thing's packed with 25 5W bulbs in its 6-foot length. But don't worry about changing them too often, because they're rated for 20,000 hours of use. If that's not enough illumination for you, you can string two Boalums together. (In luminaire marketing speak, this is called "obtaining a longer tubular composition." Fun!)
The Boalum is somewhat of a luminary among luminaires as it's on permanent exhibit at museums in Canada and Italy. You can put it on exhibit in your own home for about $500.
