Putting water on a lamp is never a good idea, unless that lamp is the WAT Lamp from Manon Leblanc. Leblanc's WAT Lamp makes light using a hydroelectric battery that needs only a little bit of water to get going.
Despite its small stature, the WAT Lamp could very well be the lamp of the future. The world is increasingly going green, and what could be greener than an off-the-grid lamp powered by tap water? Nothing -- the answer is nothing.
