Fun Light, retail $6.54 (
Manufactured by Lights of America (
Last updated 11-04-06

This is a light "blub" (yes, it's spelled "blub" in two places on the package) that has what I believe are six LEDs (2 red, 2 green, and 2 blue) inside, which are controlled by a microcontroller circuit inside the "blub" .

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 "blub" is made of glass, just like the globes on ordinary light bulbs.

It was purchased at a Wall*Mart in the central-eastern part of the United States (the state of Ohio to be specific) in early-October 2005 for $6.54. It was found in the section of the store with the regular light bulbs, not in the seasonal section.


To use the Fun Light "blub" , just screw it into any lamp socket as you see fit. Yes, it really is as easy as that.

*** 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 might let all of the magic smoke out of it and attract rats & flies - I mean start 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 "blub" was meant to be screwed in a light receptacle and not abused, I won't whap it against a steel rod or the corner of a concrete stair, 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, 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 LEDs change color approximately once every 2.1 seconds.
The color progression is:


Just like it reads on the back of many shampoo (or shampee) bottles, "lather, rinse, repeat".
In other words, the cycle starts again with the red LEDs illuminated.

The lamp runs cool to the touch, with an exterior temperature of 74F (23.3C) at an ambient temperature of 72.0F (22.2C) after appproximately one hour forty minutes of operation.

I examined this "blub" with a laser, and can see 5mm LEDs near the base. I don't have an accurate count of each LED color that might have not been printed on the package, but I can confirm that they are 5mm LEDs. I won't intentionally pop the glass "blub" to see exactly what's inside, but if it *ACCIDENTALLY* becomes broken, then yes, I'll examine the insides and post my findings (with a photograph if possible) on this web page.

See where it reads "bLUb" on the package?

Test unit was sent by a fan of the website on 10-14-05 and was received on 10-17-05.

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.

UPDATE: 12-24-05
I screwed this "blub" into the receptacle over the front porch this morning, because I think the color changing effect is rather festive. Assuming nobody steals it today or tomorrow, I'll replace it with the yellow "bug lite" that normally occupies that receptacle on 12-26-05.

UPDATE: 11-01-06
I screwed this "blub" into the light receptacle on our covered rear patio, and will allow it to operate 24/7 until it either blows out or until the holiday season is over.

UPDATE: 11-04-06
I was asked by my sister to remove the "blub" and replace it with a regular light bulb until Christmas, so that she can see on the patio at night when she lets one of the kitties in. So I'll have to find another place where it can operate 24/7 without pissing anybody off.

Very attractive color-changing effect.
Low power usage (~1 watt).
Long lifetime expected.

Glass globe means this product is rather breakable;
this is what removed that last star of its rating.
