Bruce Dawson writes: "LED lamps are very efficient at generating light, but in some cases they draw almost as much power when turned off. This makes their average energy consumption, with some usage patterns, worse than for incandescents. This problem will only be avoided if the market demands better. Write to email@example.com and insist on lamp power supplies that turn off when the lamp is turned off. We deserve that much."
