Large Rough Service Light Bulbs

Large rough service light bulbs are a higher wattage for garage shops with the swinging trouble lights. But they're also used in places where vibration is an issue such as the machine, or commercial building with door slamming or other kinds of vibrations. Building owners know that changing a bulb less often means greater savings on labor and the hassle of renting expensive equipment for high places. Home owners can now get the benefit of large rough service light bulbs in either 150 or 200 watt. These are rated at 10,000 hours which means they'll last about 13 times longer than the average retail store bulb. Long life light bulbs come in many wattages and have a clear or frosted finish which eliminated filament support shadows when lit. The size is either A12 or A23 depending on the wattage you choose.
