This is an LED bulb that has 11 LEDs (5 red, 3 green, and 3 blue) inside, which are controlled by a microcontroller circuit inside the bulb.

It screws directly into an ordinary (in the United States) medium screw receptacle, as you would find in almost all household light sockets, and operates directly from 110 to 130 volts AC 60Hz "house current".

The globe on this bulb is made of glass, just like the globes on ordinary light bulbs.

I was not able to find this product on the Bed Bath & Beyond website, so I was not able to furnish a URL to this product. The price tag on the package reads "Bed Bath & Beyond"; that's how I know it was purchased there.


To use the bulb, screw it into any standard (in north America anyway) 110-130 volts AC 60Hz medium screw base lamp socket as you see fit. The bulb comes on in "white" mode - all eleven LEDs blazing away.

To access the various modes, press and release the small button on the side of the bub base as follows:
  1. Red LEDs on.
  2. Green LEDs on.
  3. Blue LEDs on.
  4. Rapid color cycling.
  5. Smooth color wash.
  6. Off.
*** VERY IMPORTANT!!! *** This lamp must NOT be used in a fixture equipped with a dimmer switch, whether the dimmer is in the fixture itself or on the wall controlling that fixture. Doing so will cause the bulb to fail fairly quickly, and possibly quite spectacularly so if this is done.
You don't want rats or baby scorpions - I mean, you don't want an unwanted fire.

Since this product is designed to be operated on a 110 to 130 volts AC 60Hz circuit, I don't have to tell you how to change batteries in it or tell you which part to kick into a closet.

Since this bulb was meant to be screwed in a light receptacle and not abused, I won't whap it against a steel rod or the concrete patio floor, try to drown it in a toilet bowl, stomp on it, run over it, or inflict other punishments upon it that might be inflicted upon regular flashlights. So this section will be rather short.

Handle it as you would an ordinary household light bulb, and it shouldn't give you any guff.
If you drop it, the glass bulb will probably become broken, just like a regular light bulb except that there's no vaccume (vacumn, vaccuummnne, vacuume, vacum, vacuum, etc.) to relieve, so it will likely not make that satisfying "POP!" sound that you hear when you drop a regular light bulb and it breaks.

The front of the package reads that there are 12 LEDs, but there are actually 11 LEDs inside the bulb. I know this because I have a sample at my disposal with the glass bulb removed from it...here, let's go get the camera and I'll show you...snap...click...and it's off to the Fotomat I go...

Here is what the inside of the bulb looks like.
Count 12 LEDs?
Of course you don't. There are 11.

See where it reads "12 Color LEDs" on the package?
Whomever had this packaging designed for Feit Electric must have been an egg roll short of a poo poo platter when these packages were being made for this bulb.

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