I am late joining this debate. I have Litetouch dimmers, and installed 9 Philips LED lamps on one dimmed circuit. When I switched the circuit on, all LEDs came on and dimmed properly. When I switched the circuit off, one of the 9 lamps remained lit, extremely dimmed. I then took one Philips LED out, replaced it with a traditional incandescent, and everything worked fine.
It would appear that even in its off position, the dimmer passes some current through the circuit, sufficient to low-light at least one LED (randomly). With one incandescent in the circuit, it appears the low current passes through the incandescent lamp, but cannot light it, because its resistance is too high.
Can the whole problem not be solved by installing a small resistor in the circuit, which does what the incandescent lamp does for me.
Comments? Specific suggestions?
