If you’re looking to reduce costs associated with holiday lighting, your best option is the LED variety. LEDs, or Light Emitting Diodes, use as little as 2 to 4 watts per strand and can last for 20 years. They don’t use a heated filament to produce light, so they also run cooler, reducing fire risk.

Although many people love their look, halogen torchieres are the perfect example of a low-priced – and potentially dangerous – technology that proves to be costly over the long term. A 300-watt halogen torchiere used four hours a day will consume 438 kWh per year (about as much as an ENER
