L.E.D. LIGHTING: AN INVESTMENT IN ENERGY SAVINGS.
Still white-light LED lighting has moved forward dramatically since 1999. The first white light LEDs were barely white, a very light blue would be a better description. Now there’s a warm white, still not the incandescent glow consumers are comfortable with but close enough. And, white light LEDs are found in all kinds of products from Christmas tree lights, to flashlights to the latest: back lighting for flat computer displays. (I’m looking forward to one of those when (and if) prices drop.
What are some tips for saving money and energy when it comes to lighting?
Apartment energy savings can be huge when it comes to lighting. According to ENERGY STAR, if every home in the United States replaced an incandescent light bulb with an ENERGY STAR rated compact florescent bulb, enough energy would be conserved to light three million homes.
“Green Tap”- NEC develops energy-saving power strip
The device can be used for all kinds of electric appliances. The sensor monitors various data such as the luminosity, temperature, humidity or human heat around it. If you’re out of the room in which you placed your TV, for example, the sensor makes the power strip send an infrared signal to the remote control, which then makes the TV go into standby mode or turn it off completely. If you return, the TV will be turned on again.
