New LED Light Bulbs Can Replace 100W Incandescents
December 1, 2008 09:19 AM - , MetaEfficient

LED bulbs have many advantages over incandescents and compact fluorescent: LEDs use very little power, they last 10 years or more, and they contain no hazardous substances. They are also tough: they can be dropped and turned off and on repeated without damage, they can operate in very cold or warm temperatures. They can also save you money in the long term despite costing $50 (for the 100 watt equivalent Evolux) and $90 (for the 60 watt equivalent Zetalux).

Perhaps audio manufacturers need to take a cue from the computer manufacturers who’ve made many more inroads into green electronic territory.
