The average light bulb lasts about 750 hours, which can seem a very short time if the bulb is located in a hard-to-reach location. Replace your standard light bulbs with bulbs manufactured to burn up to 26 times longer than the average general service bulb. The 20,000-Hour 60-Watt light bulbs are a package of six frosted bulbs designed to burn for 20,000 hours. Instead of using an ordinary filament with no support, The 20,000-Hour 60-Watt light bulbs have an extra heavy-duty pure chemically treated 20,000-hour filament supported by five support wires and two lead wires, which help provide long life and excellent resistance to vibration and shock. They use an expensive krypton rare gas element, which reduces heat and prolongs filament life. A reflector disc protects the basing cement from heat and directs more light on your task area. The brass base eliminates corrosion and prevents the lamp from sticking in a socket. These 20,000-hour light bulbs are also available with clear glass. Long-life bulbs are also available in a variety of sizes, including 75-watt and 150-watt indoor/outdoor flood lights, and 65-watt and 120-watt indoor flood lights.
