This is a novelty keychain that has a transparent colorless plastic "light bub" on the end which glows white when you press the keychain attachment at the base. It has a 5mm (T1 3/4) white LED near the bottom of a transparent plastic "light bulb", and is powered by three LR41 button cells held in its metal screw base.


To activate it, firmly press and hold the tailpiece in. Let go of the tailpiece to deactivate it.

It comes with a medium/large split ring, to which you can affix your keys or affix to an existing keychain.

This appears to be a disposable product; there's no obvious way to access the batteries.

Unscrewing the base reveals a spring; the white battery carriage appears to be well-attached to the plastic portion of the "bulb".

This product appears to be at least somewhat splatter-resistant, but I do not for one second believe it is submersible. So water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of wild boar pee, glasses of milk, slush piles, mud puddles, tubs, root beer floats, toilet bowls, cisterns, sinks, cups of coffee, fishtanks, dog water dishes, old yucky wet mops, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in moderately bad weather.

If it fell in water and you suspect it got flooded, remove the base & spring, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater (on the beach, at a dock, etc.), got thrown into a glass of milk or a root beer float, got a Massengill brand post-menstrual disposable douche squirted on it, or if somebody or something peed on it, rinse all the parts out with fresh water before setting them out to dry. You don't want your Bulb Key-Lamp to smell like seaweed, sour milk, flowers, or piss when you go to use it next. Besides, salt (from seawater, urine, or disposable dooshes), lactic acid (from moo juice), or sugar (from root beer) can't be very good for the insides.

Although this product is disposable and can't be rated highly, I found the unit extremely difficult to turn on, so it will definitely be losing even more points for that.

Product was made in Hong Kong. A product's country of origin really does matter to some people, which is why I published it on this web page.
