quote: However, these obstacles are fading as costs slowly drop and scientists develop better material blends to provide more yellow to the LED's emissions, making for a warm light that would be welcome in many a household.
quote: Tungsten lightbulbs have a very low 5% efficiency, compared to modern LEDs, which have around a healthy 40% efficiency. The result is power savings, increased brightness, and superior life.

quote: I presume the light quality of the "EarthLed" light bulb is far better than the white LED bulbs that are found in flashlights?!?
quote: Now one place scientists are looking to plant the LED is in the home.
quote: While CFLs are an important development in energy conservation for most lighting, LED lighting has already filled a few specialist niches such as traffic lights and may have the potential to compete with CFLs in the near future. LED lamps have current efficiencies of 30% with higher levels attainable (recently up to 85 lm/w LED`s are available) , and a lifetime of around 50,000 hours, but currently are struggling to deliver the required intensity of light output for domestic uses while maintaining a reasonable working lifespan, at a reasonable cost.
