A typical household uses 4,648 kWh of electricity per year, but with Philips Genie light bulbs instead of traditional bulbs, you can save up to 80 per cent on your energy bill. With 8 powerful watts giving off 40 watts of light, you will enjoy the warm glow of these bulbs without the extreme cost. About 10,000 hours is the average Philips Genie light bulb lifespan, which means these bulbs should be able to last up to 10 years. Their slim design and compact size make installation easy as well as their quick start, unlike first-generation, energy-saving bulbs. These light bulbs are also available in bulk so that you can replace all of the bulbs in your home for maximum energy savings. You want to enjoy bright light without the hassle of high bills and hot lights. Energy-efficient bulbs, like the Philips Genie, will not give off excess heat but will instead light your home with brightness and warmth.
