Incandescent bulbs emit about 90% of the energy they use as heat, not light. Not only is that 90% wasted for purposes of illumination, but it makes your A/C work harder in the summertime. As a result, you get a 2-for-1 boost to your electricity bill – you’re paying for it twice!
Here in the Philadelphia area, a single 60-watt incandescent bulb, in use for 3 hours each day, will cost you about $11 in electricity each year – plus the cost of a new bulb annually. An LED replacement bulb uses only $2 worth of power, costs as little as $8, after subsidies, and will last for 25 years.
Because the initial cost of LED bulbs can add up pretty quickly, replace just a few at a time, starting with the ones you use most often. As your budget permits – and as prices continue to drop – you can gradually replace all your most important lamps. You can find LED bulbs in the most common shapes and sizes. Don’t worry about the “specialty” bulbs that have no equivalents – in most cases, you don’t use them all that much anyway.
