This is a fluorescent "blacklight" (produces UVA radiation; aka. "longwave ultraviolet"); its primary purpose is to cause fluorescence (glowing) in a variety of materials and objects.
This bulb would be most likely to get used on Halloween; though you most certainly aren't limited to using it just on that one day.
It is advertised to use just 13 watts at 120 volts. I measured this at 10.40 watts using a "Kill-A-Watt" meter.
It comes equipped with a medium screw base (size E26 or E27) aka. "Edison base".
To use this bulb, just screw it into any light fixture with an E26 or E27 medium screw base.
The only warnings I have regarding its use are that it must ***NOT*** be used in a fixture controlled with a dimmer switch -- whether that dimmer is on the wall or in the fixture itself; and it must not be used in a fixture controlled by a photoelectric ("day/night") sensor. This bulb will rapidly (and possibly quite spectacularly) fail if this is done...you don't want baby Emperor scorpions or mayfly larvae...I mean an UNWANTED FIRE!!!
This product is designed to be operated from "house current" (110 volts to 130 volts AC 60Hz with a sinusoidial waveform), not batteries of any type, so I do not have to tell you which part to remove, huck down the basement stairs into the room crawling with thousands of hungry carpenter ants, and then rather emphatically tell you not to.
This is a fluorescent light bulb, not a flashlight designed to be thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a patio, use a small sledgehammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island), send it to the Daystrom Institute for additional analysis, or inflict upon it punishments that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.

The purple light you see here is ***SIGNIFICANTLY*** more intense than it is in reality!!!

Much cooler-running than incandescent "blacklight" light bulbs
Much more UVA output than incandescent "blacklight" bulbs
Much longer expected life than incandescents
Uses a lot less power than incandescents
Runs a bit on the hot side at 170.00°F (76.67°C) -- this is what nocked that last ― star off
