Available Options & Add To Cart
150 watt A21 long life light bulbs have been a regular use item for many commercial buildings for many years. The larger bulb makes possible higher wattage and a longer neck for deeper recessed lighting. These are rated at 10,000 hours which means they'll last about 13 times longer than the average retail store bulb. 150 watt A21 long life light bulbs have a clear or frosted finish which eliminated filament support shadows when lit. These light bulbs also are known as a vibration service or rough service variety as they withstand machine vibration or simply the slamming door in a home.
