Experimenting with capacitative reactance, I'm getting 0.7VDC across 16.8 ohms with 0.88uF of polyester film capacitors. I need 6 volts across 8 ohms to match what the LED tent lamps from Wal-Mart use. So, assuming it's linear, I need about 20 times the capacitance. A 22uF cap ought to be pretty close. This is, in case it's not clear, with about 120VAC at 60Hz.
