CFL "Bug Lite" Light Bulb, retail $8.36 (

Last updated 06-10-10

This is a CFL (Compact Fluorescent Lamp) "bug lite" light bulb.

It's called a "bug lite" because it lacks wavelengths shorter than 520nm (bluish-green) -- that means that there is no blue-green, blue, violet, or ultraviolet radiation that many nocturnal (night) flying insects are attracted to.

It is advertised to use just 13 watts at 120 volts. I measured this at 10.10 watts using a "Kill-A-Watt" meter.

It comes equipped with a medium screw base (size E26 or E27) aka. "Edison base".

 Size of product w/hand to show scale SIZE

To use this bulb, just replace the old incandescent "bug lite" bulb in your porch light or other light fixture with an E26 or E27 medium screw base with this bub.

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 don't want baby brown recluse spiders or stag beetle grubs (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 piss 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 {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), 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.

Spectrographic analysis of this bug light bulb; spectrometer's response narrowed to a range between 175nm & 550nm -- input deliberately "overloaded" to show the lack of UV, violet, and blue spectral features.

Test unit was sent by a website fan quite a number of years ago.

UPDATE: 00-00-00

Much cooler-running than incandescent "bug lite" light bulbs
Much longer expected life than incandescents
Uses a lot less power than incandescents

None that I've yet to discover
