This sale is for one premium quality 45W photo fluorescent bulb. This bulb has a standard E26 Edison socket, so it will fit into any standard light receptacle. The 45W bulb is equivalent to a 150W incandescent lamp. These bulbs are flicker-free and the average life is 8,000 hours. These bulbs are daylight balanced so there is no need for extra filtration or color correction. Lower heat, correct daylight color balance and long life make these the perfect alternative to incandescent photo floods. These bulbs are a great addition for your photography and video needs. These can also be used as: grow light bulb, craft light bulb, and a reading light bulb. *About Fluorescent Lighting Fluorescent lamps are more efficient than incandescent light bulbs because a greater proportion of the power used is converted into useable light rather than heat, allowing the fluorescent lamp to run cooler. Thus a fluorescent lamp requiring 45 watts of power, for instance, produces as much light as a 150 watt incandescent light bulb, but with up to 90% less heat
