Long-life 150-watt flood light bulb burns 20,000 hours before needing replacement.
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 indoor or outdoor flood light bulbs with bulbs manufactured
to burn at least 10 times longer than the average general service bulb.
The 20,000-Hour 150-Watt Indoor/Outdoor Flood Light Bulb is designed to burn for 20,000 hours and has an extra
heavy-duty pure chemically treated 20,000-hour filament supported by
five support wires and two lead wires.
This helps provide long life and excellent resistance to vibration and shock.
The bulb uses 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.
Folks this will probably involve a ladder to install. Please be careful, make sure the ladder will support all your weight and always wear gloves
