Edison the Petit, undressed. The Fatboy Transloetje is a transparent version of that original--and popular--lighting design. In addition to revealing all the lamp's cool interior mechanisms, the clear colored plastic shows off an old-fashioned bulb, which is actually an energy efficient LED in disguise. Charge for up to 8 hours of light at the highest dimmer setting, or tap the touch dimmer on the base for softer, longer-lasting light.
