As we enter the summer months, high air-conditioning bills seem just as inevitable as death and taxes. Something most people don't think about is that incandescent and halogen bulbs act as miniature space heaters, dumping over 90% of the energy they consume into heatâ€¦ heating up your already-hot home. This means your air-conditioning has to work harder to keep you cool. LED lighting uses a fraction of the energy consumed by traditional light sources. They generate very little heat (3 BTUs/hr vs. 85 BTUs/hr for incandescent bulbs) and remain cool during operation, thus easing the burden on your air conditioning system during hot weather and reducing your overall energy costs. For every 60W incandescent (traditional) light bulb, you're spending about $13.86 more in cooling costs per year (based on Nashville/TVA's current electricity rate of 10.252 cents per kilowatt-hour) versus an equivalent LED bulb, so it can quickly add up! Even when you consider the initial cost of LED bulbs (currently about $2.48 for a 60W equivalent bulb, compared to about $1.00 for a traditional 60W bulb), the payback period is just 6 months for a light that stays on 8 hours per day.. The savings come from reduced electricity to produce the light as well as the reduced cooling costs. And just in case you're thinking that the heat generated from traditional lighting might be beneficial in the winter to help keep you warm, it's an extremely inefficient heat source, costing over 5 times as much as the typical gas furnace to generate the equivalent amount of heat. Compact fluorescent light bulbs (CFLs) were promoted as an energy-saving alternative, but they're no match for LED lighting, and are falling out of favor.
LED stands for light-emitting diode. The light is generated by a semiconductor, creating an effect known as electroluminescence.

It's time to convert to LEDs now!
