Remote Control RGB LED Light Bulb #E27-RGB, retail $49.95

This is an RGB LED light bulb with a twist: you can actually modify how it displays colors with a remote control!!! The bulb screws into any standard (in the US and Canada anyway) medium screw base light receptacle.

I haven't yet learned all of its functions, so this page may appear a bit incomplete, at least in the near-term.

SIZE

Feed the remote control its two included AAA cells first. You'll be needing the remote in a short time.

To use this bulb, just screw it into any medium screw base female light bulb receptacle (commonly called just a "light socket"), fed by 110 to 240 volts AC 50-60Hz.

***VERY IMPORTANT!!!*** DO NOT under any circumstances screw this bulb into a fixture controlled by a dimmer switch, whether that switch is on the wall or on the fixture itself. It WILL fail fairly quickly, and possibly quite spectacularly so, if this is done.

You don't want dragonfly larvae or baby brown recluse spiders...I mean...you don't want an unwanted fire.

When the unit is first powered up, it will come on in a color wash mode, where the bulb will smoothly cycle through the color spectrum with a cycle time of approximately three seconds.

Aim the front of the remote control in the general direction of the bulb, and start pushing buttons.

See, told you I didn't know much about this bulb yet!!!

It came with no instructional material, so I'll just have to fly by the seat of my pants for awhile here.

This product was intended specifically to be used in a 110-240 volts AC light bulb receptacle, so I don't have to tell you how to change the batteries in it or tell you which part to remove and throw into the woods.

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 floor of a patio, 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.

What makes this color-changing LED product different from all the others is that it comes with a remote control. Not just any universal remote either, but one made *SPECIFICALLY* for this bulb!!!

Here's a photograph of the remote control itself.

Like I said earlier, I haven't yet learned all of the functions of this bulb, so this web page may appear a bit incomplete, at least in the near term.

The dimmer settings use a method called PWM (Pulse Width Modulation) to achieve dimming, in which the LEDs receive pulses of full current with periods of no current at all between pulses. See the last photograph on this web page for an example of PWM. When the photograph was taken, the bulb was emitting a purple color.

After just under 1 hour of operation in slow fade mode at full intensity, the outside of the bulb measures 112°F (44.4°C).

Test unit was purchased on Ebay on 09-16-06, and was received on 09-20-06.

UPDATE: 11-03-10
I used this bulb on our front porch on Halloween evening; I had it in color wash mode -- this gave a rather spooky ambiance in concert with the other Halloween decorations out there.
Needless to say, it was a smash hit both with Trick Or Treaters and their parents!
