I've been an X10 user for many years.  Several years ago I added a nine module (by Leviton) system  to my outdoor living area. I placed 12 inline modules in a water tight electrical box.   I have several wireless remotes which operate the receiver. Two years later I encountered problems with the dimming modules. The lights had a flicker (about 30 HZ). That module would turn on but not off. I replaced the module twice and I experienced the same problem after a few days. Do I keep replacing modules, assuming I had a faulty shipment, or troubleshoot using your suggestions?

Inline modules probably have the Neutral Power wire. They are not the two wire ones that get their power through the load correct?

Do you happen to have the Leviton part number so we have a better idea of what you have?

What type of bulbs? Incadescent, LED, Low Voltage, CFL?

If they worked for a few years and are now giving problems. I would inspect the wiring, connections and the lamps sockets. For corrosion or poor contacts.

Thanks for the reply; yes, it is a three wire module. The Leviton catalog # is 6376. The bulb type is incandescent encapsulated in a rope. Would I get better results using X10 modules?

I have three "stupid" questions:
1. Are you sure the bulbs are incandescent?
2. Did you unplug and replug the rope prior to the problem starting?
3. Could anything else be sending X10 commands (including DIM or BRI) commands when you see the flicker? (not on the same HCUC as the rope).

[Brian H]

I doubt X10 modules would work better.
I believe Leviton models have AGC for noise reduction.
Do you have any idea what the total wattage on each 6376? I can't find any minimun wattage for that module.
I know the X10Pro XPDF dimmer fixture module say 40-300 watts. Lower than 40 watts may flicker.

That is true for many of the Leviton wall switches, but the Leviton catalog does not say the fixture modules include "Intellisense".  They appear to be an exact clone of the X10 inline modules.  They are probably just re-branded X10 devices, like some of the other Leviton modules.

The total wattage is 300w. I am up to about 250w.

1. definitely yes
2. No I did not
3. Only one neighbor close by. Other modules not flickering. What is HCUC?

[Brian H]

HC= House Code
UC= Unit Code

My #3 was actually aimed at your system. I have lights that I can see flicker WHEN my controller is sending commands and thought perhaps that may be what you are seeing on the rope.
In answer to your original question of: "Do I keep replacing modules, assuming I had a faulty shipment". My answer (WAG) is no, but considering your three answers,  I am now shooting wadding, so can't help. Sorry

One thing that might help is a pointer to some specs on your specific incandescent ropes. They're new to me and I suspect to most others here.

FWIW typical is one grain o wheat bulb per inch, app 3 watts per foot.

Here is another FWIW to pfeffer:
Back in the 90's when rope lights were insanely expensive, I made my own by threading minature Christmas lights in a vinyl tube. I drove the 100 foot, home made rope with a Lamp Module. One night I noticed the rope doing an erratic glimmer (not quite a flicker). We had had very heavy rains and several feet of the non waterproof rope was submerged in puddles. (No GFI on that circuit).

Commercial rope should be waterproof, but you don't have any couplings under water, do you?

[Brian H]

I did a check of some vendors. They do make 120 volt incandescent rope lights.
These are 4 watts per foot and a 150 foot roll. That is 600 watts.

I found some listed for 120V but also found some on the HomeDepot website that have 5V bulbs.
