Sticky Lights, created by Chris Kabel for Droog Design, are light bulbs in a plastic case that, uh, stick to walls. They cost $27 per unit, and you have to buy at least two. They stick using an adhesive back, so you basically get one shot at placement before the glue wears off and they fall off the damn wall. But really, what more would you expect from a light bulb that sucks to walls? Did I say suck? I meant stick. They stick to walls. Sucking is just an added bonus.
