I'd be curious to hear anyone's experience with this or a similar circuit, as well as any improvements you discover or implement. Punch outs in the junction box allow for easy entry of the incoming line cord, and a convenient starting point for mounting a lamp socket. But once people began making use of LED lights in their homes, they noticed a down side. However, it does mean that you can make LED Christmas lights using LEDs and absolutely no external driving circuitry, which makes them very cheap to make. To stop the flickering, add a power conditioner to the line supplying the power to the LED. One brief word about this "warm white" thing, unrelated to this article. 5 Reasons Why Light Bulbs Flicker . Your Christmas LEDs only conduct current in one direction, so they flicker at the power line frequency (60 Hz in the U.S., 50 or 60 Hz elsewhere depending on where you are). And its had some unexpected benefits too! So that's all there is too it. Beyond being functional, the dim glowing lamp in the project makes for a fun looking "steam punk" conversation piece. If the whole string lights up, you're done. In my initial bench experiments I used a 30uF motor start capacitor with multiple 100 LED sets, and even that was adequate to solve the flicker problem.That was a large non electrolytic cap. I’m hoping I can make it work. And, I have even switched to a 25watt "ballast" lamp, which means more current/brightness than my original 4W lamp provided, because the lamp resistance is lower.
