Unlike CFLs, LED Lamps contain no mercury. For more on Fluorescent lamps and mercury, see end-of-life management and Mercury in Fish .
LED direct replacement lamps are now available for 2pin and screw base Halogen Lamps. With a life expectancy of 40,000 hours, they would last 4.5 years, if left on 24hours, 365 days a year. The electricity costs would be about 10% of the equivalent Halogen lamps. This makes them ideal spotlights in libraries, shops and galleries.
In the case of Downlights and Tracklights, each 2-Pin 12 Volts Halogen Lamp uses 35W whereas the LED equivalent uses just 3.8W (4.5 LED replaces 45W Halogen).
In bathrooms which are only used for a short period and require bright lighting there are 9W and 15W Screw Base LED Lamps available to directly replace unsatisfactory CFL or 60Watt,75Watt and 100Watt Incandescents or their Halogen equivalents. LEDs provide instant light.

Comparative Lamp Technology Lifetime
manufacturers have begun using the L70 language, stating that their white LEDs "are projected" to have lumen maintenance of greater than 70% on average after 50,000 hours when used in accordance with published guidelines.
|Light Source||Range of Typical Rated Life (hours)* (varies by specific lamp type)||Estimated Useful Life L70|
|High-Power White LED||35,000-50,000|
