F40T12 blacklight Blue bulbs are the typical lamp used for several types of effects including the most common one which is blacklight Blue displays and effects. They're also used for stage lighting effects and nighttime scenes that require a special dark sky effect but have colors that jump out of a display. These are 48" inches long from pin to pin and are the same size as standard T12 lamps that you might use in an office overhead light fixture. The effect is most pronounced when all other visible light sources are turned off, that washes out the effect, so best to use it in total darkness. Like any other 40 watt T12 lamp, this bulb operates on the same magnetic ballast so that you can use this bulb anywhere you have a regular F40T12 fluorescent lamp. That also includes multiple lamp configurations; it doesn't matter. So you can get the great blacklight blue effect with almost any fixture that's on the market today. T12 fluorescent bulbs are probably the most pervasive in every office lighting situation and even for homes. If you need a new fixture to use this light in we, have many T12 light fixtures that will accommodate this bulb. So as long as it operates in F40T12, you're going to be able to use this blacklight Blue bulb. Keep in mind that if you have a larger area, you're going to need quite a few of these lamps to properly give the blacklight blue effect. You wont be able to just put one or two lamps in a very large area and have it do it's job. Of course, for smaller spaces, you might be able to get by with a two lamps strip fixture something like that, but for a large area you're going to need several light fixtures with these lamps in them. Sometimes people call these purple light bulbs but the effect is not purple, it has a particular area of the spectrum to create the blacklight Blue you need.
