Tip # 2
Save energy and money upto 90% by replacing old incandescent bulbs with LEDs. When you turn on an incandescent light bulb, only 10% of the electricity used is turned into light. The other 90% is wasted as heat. Still want the warm bulb effect? Go for options in LED. Switching to LEDs will use 90% less energy and last far longer than the incandescent lights.
PS: They are smarter & safer than CFL bulbs
