LED bulbs can operate for 50,000 hours or more. One LED light bulb can easily outlast 30 incandescent bulbs, or 6 compact fluorescents! LED bulbs cost less than the bulbs they replace. Operating 12 hours per day, LED light bulbs can last 7 years or more!
LED light bulbs are not sensitive to shock, vibration, or the extreme temperature changes that can quickly ruin fragile incandescent bulbs. And unlike fluorescent bulbs which wear out much faster if they are frequently turned on and off, LED bulbs are not affected by frequent on-off switching.
The long life of LED light bulbs reduce the time, effort and cost of replacement.
The lighting efficiency of the new high power LED light bulbs is nearly eight times that of incandescent lights, and twice as high as compact fluorescent lights. LED bulbs also emit a much higher percentage of light in the desired direction. This makes them even more efficient compared to either incandescent or fluorescent for task lighting, desk lamps, reading lights, spotlights, flood lights, and track lighting.
With coloured LED lights there is simply no comparison. All of the light output from LED bulbs can be a specific colour. With other light sources, much of the light produced consists of unwanted colours which must be filtered out.
LED light bulbs also generate very little unwanted heat. The energy savings may be doubled in air-conditioned environments where each watt of incandescent lighting can add another watt or more to the power needed for air conditioning.
The EPA encourages the use of innovative light source technologies such as LED light bulbs.
