Industrial A Shape Incandescent lightbulbs
H&H bulbs are designed and engineered for durability, strength, and long burning life. They feature rugged multi-support filaments that stand up to the shock and vibration common to industrial applications. Life-rated up to 16,000 hours, the H&H bulb will outlast ordinary bulbs many times over. You save substantially on labor and replacement costs while greatly reducing the number of bulb-changing operations.
All H&H incandescents feature brass bases which, unlike aluminum, won't freeze or corrode in the socket, even after thousands of hours of use. In wattages ranging from 15 to 200, our "A" line includes, general service lamps in clear and frost, sign lamps, colored lamps, rough service models, and much more.
