LED Lightbulb

Step 2 Assembly

You need to start by cleaning out the lightbulb, there are numerous instructables with this step and I will forgo it here.

The circuit consists of two LED's wired in opposition, I ground down the LED's just short of the die and glued them together to make a single double LED. Twist the legs of the LED's together, on one side solder the capacitor, the other the resistor. Simple.

Is it really necessary to wire two LEDs in opposition? Is the flicker noticable if you didn't?

Yes, its necessary, but not because of flicker. LED's have a "reverse breakdown voltage" of only about 5 volts, so a single LED would break down as soon as the line voltage reversed direction. Although the capacitor and resistor might prevent instantaneous destruction, the LED lifetime would likely be reduced. By putting a second LED across the first LED, with opposite polarity, the two LED's protect each other from high reverse voltage, and double the light output, and reduce flicker. What a deal!

Dunno, try it and let us know.

Ah yes, I forgot about that. Thanks!

Hi, nice one, but what about the capacitor plarity, how do I hook it, negative side to led or the oether way? Thanks

You need a non polarized capacitor.

I'm a new member ! So, i need you explain more to connect 2 led together.
You can post 1 picture of wiring diagram. Thanks !

Wired in opposition? ie positive to postive ? please clarify this point for the clueless. thanks :)

[Tool Using Animal]

Negative to positive, positive to negative.

Just a quick side comment, I can understand not wanting to "recreate the wheel" for cleaning out the bulb but a quick link to one of these other instructables would be more convenient for the reader. Other than that, this looks very interesting. I'm definitely trying this. I might replace every bulb in the house. ;)
