I lasted three years until I got a boss straight out of a Dilbert cartoon. Did I mention that capacitive reactance is at right angles to the resistance of the LEDs?

S storre New Member Feb 21, 2009 #24 I'm trying to do something related to this topic. I want to do something similar to this with a maximum of about 50 LEDs. I'm hoping to get about 168 lumens. Circuit - AC Powered White LED Strings I'm thinking to use water white LEDs 4000MCD and 60 degrees. Approximate luminous flux: 3.367 lumens each LED. 4volts at 30 ma is 0.12w. 50X = 6 watts. Lumens efficiency is 3.367 / 0.12 = 28 lumens/watt = 168 total lumens I also found something similar. **broken link removed** My question is does this type of circuit work with dimmers such as: **broken link removed**
