1W LED LIGHT BULB

This is a household light bulb designed to be screwed into a standard E26 (medium screw base) light socket, and powered directly from 110 to 130 volts AC 60Hz.

It features a 1 watt LED with a milky glass "bulb" around the LED to diffuse the light, so the light is radiated a true 360° around the bulb, and out the top and somewhat out the bottom too.


SIZE



The bulb is ready to use as soon as you receive it. Screw it into any standard medium base 110 to 130 volts AC receptacle.
Then, to borrow a phrase from a TV commercial, "plug it in, plug it in!"

For the purposes of this web page, I used a portable trouble light to power this bulb with.



Since this product is designed to be operated from 110-130VAC, this section can be skipped.



This is an LED bulb, not a flashlight. So I won't slam it against a steel rod, try to drown it in the john, stomp on it, run over it with a 400lb electric Rascalator thing, 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 glass with a plastic cylinder between the screw base and bulb. So it CAN become broken if dropped, thrown, or otherwise abused. 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: Cool White, Warm White, Blue, Green, Amber, and Red.
As you can see, the one I've evaluated for you today is the blue bulb.

The base reached a temperature of approximately 99°F (37.2°C) after several hours of continuous operation. The glass bulb remained cool to the touch (84°F (28.9°C) with an ambient temperature of 73°F (22.8°C)).
The bulb was used base-down for these measurements.

***VERY IMPORTANT!!!*** DO NOT under any circumstances use this bulb in a fixture equipped with a dimmer switch, whether the dimmer is in the fixture itself or on the wall controlling that fixture. The bulb will overheat and fail if this is done. You don't want rats or rattlesnake eggs...I mean...you don't want an unwanted fire.

The caution regarding using a dimmer is pretty much generic for any LED product powered by 110-130 volts AC; not just this bulb. Using this or any other 110-130 volts (or for that matter, 220-240 volts for viewers outside North America) AC LED product can result in overheating, failure, and possible fire because the AC waveform is altered by the circuitry in the dimmer, and AC line-powered LED products not using a step-down transformer tend to not do well with the altered AC waveform.

This bulb has a dedicated power supply in it, not just some resistors, capacitors (or "capacitators" as some people call them, or "condensers" that was the old fashioned term), and diodes; as I detect no flickering as the lamp is rapidly waved about while turned on.

(Update 02-01-06): There is a dot of color on the plastic ring between the metal base and the glass bulb; this tells you the color of the bulb without your having to install and energize it.
