LIGHTING
What defines energy efficient lighting?
• reduce wattage
• proper disposal available to consumer
• ease of recycling materials
• longer lasting bulbs
• suitable luminance for type of activity
2 Most popular and up coming choices of today are :
CFL-operate on 9 to 25 watts of energy while emitting the same amount of light as an incandescent bulb . Its life span is more than 10 times longer that the traditional bulb. CFLs produce ultraviolet light, made visible through phosphor coating on the glass.
LEDs- convert electric energy directly into light of a single color. Because they employ “cold” light generation technology, in which most of the energy is delivered in the visible spectrum, LEDs don't waste energy in the form of non-light producing heat.
