A great leap in green technology has been made by LSG and Dixon in developing an affordable 60 watt equivalent LED bulb. Anticipated retail in the US is $15.This bulb was developed in India which is experiencing an explosion in electricity and lighting demand and has set a goal of phasing out incandescent bulbs by 2012. Phase-outs and bans on incadescent bulbs are being pursued by several countries as an effort to reduce energy demand. The countries that are leading the way on this change are a mix of developed and devloping countries united by concerns over growing energy demand, limited resources, and environmental impact. The United States Congress passed legislation in 2007 which will phase out incandescents starting with 100 watt bulbs in 2012.
The primary bulb alternatives for the US consumer market are compact fluorescents bulbs (CFLs) and light emitting diodes (LEDs). The major complaints about CFLs are unappealing light quality and mercury content which is an issue for bulb disposal or in the case of breakage during use. LEDs offer appealing variety and control of light quality and no mercury content but have long been more expensive than CFLs. The good news is that CFLs provided a transitional solution and drastic improvement over the flickering fluorescent bulbs that were the standard for commercial and industrial space and horror movie ambience. The better news is that governmental, environmental, and economic pressure have resulted in the development of even better alternatives.
Those of us who live outside India will have to wait until 2012 to buy these bulbs but can take hope in the growing list of affordable and environmentally sensitive technologies.
