Rough Service Light Bulbs
Rough service light bulbs are manufactured with the stronger filament to make them more durable in environments where they might be subjected to frequent vibrations. These types of vibrations often cause regular bulbs to fail early due to putting stress on the filaments. Rough service bulbs are made to withstand these vibrations.
Rich Tool Systems carries rough service light bulbs perfect for home and workshop use. These long-lasting bulbs are great for use near heavy equipment, industrial doors, or anywhere else regular bulbs tend to fail quickly. We have 75 watts and 100-watt rough service bulbs in cases of 120.
