ENERGY STAR qualified light bulbs and lighting fixtures use up to 75% less energy than standard lighting products.
90% of the energy expended by an incandescent light bulb is wasted as heat. Only 10% of the energy (electricity) that passes through is converted into visible light. ENERGY STAR qualified lighting fixtures use less energy, provide the same light output, and are cooler to the touch.
An ENERGY STAR qualified light bulb that is used for an average of 4 hours per day will last for more than 4 years before it needs to be changed.
A typical household spends about $90 per year, or 10% to 15% of its annual electrical bill, on lighting.
