GX5.3 BASE: These bulbs have a GX5.3 base that make the installation effortless. Simply install the bulb directly into a compatible base accessory or socket. Our bulbs are the smart choice for replacements of canister light bulbs, wall sconces, chandeliers and other compatible fixtures in your home or business. HALOGEN LIGHTING: The bulb temperature of GoodBulb’s Halogen lights give off a Soft White color that makes these bulbs perfect for any common area or work space. Our halogen bulbs emit a soft light that is able to easily brighten your office space, lobby, hotel, living room, bedroom, or any room in your home or business. LONG-LASTING: Not only should a light give off the perfect glow but it should also perform well and have a long lifespan. These bulbs have a lifespan of 4000 hours, so they don't have to be replaced as often as normal incandescent lights or strips (which only last about 1,000 hours on average). This pack comes with 10 clear 71-watt bulbs. VERSATILE LIGHTING: GoodBulb’s halogen light bulbs are stylish and functional, allowing you to light up any space. Use them on your hanging pendant lights to save your eyes from harsh lighting. They also make perfect accent lighting for anywhere that may need lighting. GOOD CAUSES: Buy Light. Give Light. One in every seven people in the world live without electricity. A portion of every GoodBulb purchase is used to provide solar powered LED lanterns to families living without electricity. Selecting GoodBulb is a decision to be a light in the darkness. Together, we can make a difference!
