Available Options & Add To Cart
40 watt long life light bulbs have been a standard item for many commercial buildings to reduce the labor cost of changing light bulbs. These have a medium wattage for those places that need a moderate light, but very long lasting performance. 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 wattage and have a clear or frosted finish which eliminated filament support shadows when lit. These 40 watt long life light bulbs also are known as a vibration service or rough service variety as they withstand machine vibration.
