LM15A
« on: November 12, 2021, 11:16:43 PM »

Just wondering if anyone knows where I can buy some socket rockets (working) online from a reputable source.

If you want to go the X10 site.
They list the LM15A for sale.
https://www.x10.com/collections/x10-lamp-modules/products/lm15a

Off hand I don't know of any other independent users.
Like someone who is clearing out excessive X10 modules or moving on to a new automation protocol.

Did find Big Johns' Place on Ebay also has CM15A modules. I have used his site a few times and got fresh stock.

Thanks Brian H and brobin for your replies. Thought I needed new LM15A's because they stopped working, but now they have magically started working after I removed them for awhile and then reinstalled them! Not sure what's up with that. Read somewhere on the internet that they can overheat, so maybe it was that---and if so, probably dangerous?

Over heating may be what it has in its socket.
40 watts to 150 watts incandescent bulbs is what it was designed for.
Others here may have dimmable LED bulbs in them with good results. Though I imagine the exact LED bulbs design may be a factor.

I've been using a NOMA dimmable 60W equivalent LED.....is there another brand that's better?
Think maybe it's time to switch to something like Phillips HUE, but of course, it won't work with my x10 system.

I don't have any LED bulbs in mind.
Since the LM15A is On and Off only with a triac.
I imagine most would play nice.
Now if the LM15A can be reliably turned On but not off. Than I would suspect the LED bulb was making power line noise when On.

I tried using one for a set of outdoor xmas lights one year.  They stopped working and after investigation I found it charred.  Turns out I misread the box and the lights were pulling a lot more current than expected.  Fortunately, it just burned up the regulator and charred everything else around it rather than starting a fire.  I'm not using them anymore, but they should be ok for what they are rated at (150W or maybe 300W IIRC).

The problem with the socket rockets happened when I had to replace a fluorescent light tube in the kitchen. The socket rockets were on at the time, and then would not turn off. Could the fluorescent light tube have created the noise?

Good to know. Thanks.

Yes, they can interfere with signals.

Fluorescent light are one of the electric  devices that can make power line noise or absorb the power line signals.

You may find some interesting trouble shooting information on Jeff's sight.
