With the push towards LED lighting (as filament lamps are due to be banned in 2012 in most countries), there is incredible research going on into lighting that offers the equivalent light output and light color, but at the fraction of the energy consumption. The Zetalux LED light uses only 7 Watts of power, but is comparable to a 50-60 Watt Light bulb! The light is high efficiency and does not consist of any harmful raw materials.
The light output from the Zetalux and Evolux (100W equivalent) has been optimized in both directions and in color. Although these light bulbs cost $50 and $80 respectively (compared to around $1.50 for an incandescent lamp), the cost savings from reduced energy usage is incredible. Over the 10 year life of a Zetalux bulb, it will cost roughly $150 less in electricity!
For those of you who know more about light color than I do, here are some statistics for the Zetalux bulb:
Luminous Flux: 450 (Cool White), 350 (Warm White)
Color Temperature: 3000 K (Warm), 6000 K (Cool)
CRI: 75 – Cool, 80 – Warm
Beam Angle – 180 degrees overall
