Last updated 07-29-06

These are TMI part # TM-P19S LED light bulbs. They are designed to be operated directly from 110 to 130 volts AC 60Hz, and screw into any E26 (medium screw base) light receptacle, and use just two watts (2W) each.

There are 19 LEDs in each bulb, and they are protected by a water-clear, transparent plastic dome.

The bodies are all-plastic, and have a male medium screw base; just like common household light bulbs in North America have.


To use this bulb, just find a fixture you want to use it in, unscrew and throw the old bulb (love to hear those things pop!!!), and screw this bulb into the socket in its place. If you're adverse to breaking things, gently place the old bulb on a washrag or something in a drawer full of really soft fuzzy things.

Since this bulb was designed exclusively to be powered by 110-120VAC, this section can and will be skipped.

This is an LED bulb, not a flashlight. So I won't slam it against a steel rod or the concrete floor of a patio, try to drown it in the john, stomp on it, run over it with a 450lb electric Celebralator thing (motorised wheelchair), throw it at a wall-mounted porcelain urinator to see if it smashes open (the bulb, not the urinator), or subject it to other indecencies that a flashlight might be subject to. This bulb is made primarily of plastic with a metal screw base Handle it as you would an ordinary household light bulb, and it shouldn't give you any guff.

Since this is a light bulb with a set purpose, I don't have a whole lot more to say about it.

The base of this bulb is E26 (26mm), which is the standard medium screw base that is used by household light blubs in the United States.

This bulb is available in the following colors: White, Blue, Green, Amber, and Red.
As you can see, the ones I've evaluated for you today are the red, green, and blue bulbs.

The LEDs in these bulbs aren't round, they're oval, so the beam produced by them is somewhat elliptical, not circular.
