Unlike CFLs, LED Lamps contain no mercury. For more on Fluorescent lamps and mercury, see end-of-life management and Mercury in Fish .
LED stands for light-emitting diode. LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material. LEDs can be integrated into all sorts of products to provide white and colored light, such as flashlights, light bulbs, and integrated light fixtures....www.energystar.gov
1939: Early in this year (around Feb-March) GE introduced the now ubiquitous 48 inch (4 ft) 1-1/2 in. Diameter T-12, 40 watt MAZDA F lamp. Initially there was much skepticism among GE engineers that such a long lamp was not practical or even possible to manufacture. Again GE accomplished the "impossible"! Like the 30 watt lamp, this new lamp at first used 240 volt choke ballast and a step-up transformer if used on a 120 v circuit. This size quickly became and remains to this day, the most popular fluorescent lamp ever made! Even today's 4 foot T-8 F lamps aren't at all "high tech" and were made experimentally in 1939!...edisontechcenter.org

450,000 hours for LED Tubes is conservative. The tubes are being quoted at 50-100,000 hours. A website (viewed 7 December 2011) pushing the T5 approach quotes: "LED bulbs can have anywhere between 35,000 - 50,000 useful life hours, while linear fluorescent bulbs maintain anywhere between 20,000- 30,000 useful life hours.
FluoroCycle (www.fluorocycle.org.au) is a voluntary, national scheme that aims to increase recycling of mercury-containing lamps. It commenced operations on 21 July 2010. The initial focus of the scheme is on those sectors that account for the largest consumption of mercury containing lamps, the commercial and public lighting sectors....A variety of lamp types used in Australia require mercury to operate. Generally, the higher the power usage, the more mercury that is required to operate the lamp...www.environment.gov.au
While LED Lighting does not contain mercury and has a long life, its electronic and plastic components will eventually pose an e-waste problem or resource.
