150 Watt A21 Long Life Light Bulbs
Options and 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. These 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.
