Tried it with Phillips c6 and a generic led during still flickering for me. Basically I'm using a low wattage 120VAC incandescent lamp, as a cheap power resistor. 4.5 out of 5 stars 202. Activate the heat shrink. Light from LEDs are generated in a much more complicated way and involve valence bands of energy and lots of science. Blinking Christmas Light Circuit Diagram. Light bulbs that aren’t fully secured in their sockets are receiving inconsistent power, which results in inconsistent lighting. Live and learn. Well a higher wattage resistor like this would be a hard to find part and if you string 5 or more LED sets together, they will require even more power to reach the same brightness. The capacitor still doesn't hurt, and the 'balast' lamp also seems to make even the cheapest 'walmart' light sets last a lot longer than they do plugged directly into straight AC. Warm white, of course, is intended to look like incandescent bulbs. 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. Step 3 Plug the flasher bulb into the socket.
