    Elation, then ADJ used to make something called the LED Dummy, but apparently they've both discontinued it. Is somebody else making a similar thing? Thanks,

    Yep, I've spoken to Elation and ADJ both.

    Well then, electric heaters, heating pads, incandescent light bulbs, irons, toasters, crock pot, etc. - take you pick.

    An incandescent nightlight does the trick.

    Yes, and the advantage is they don't throw any heat. They work by doing their magic right at zero-voltage-crossing, where the problem is.
    I've always wondered why others didn't hit the market as it is a solid solution to a common problem. Now, it looks like these are about to disappear. Go figure!

    Oh, no. Those things are great. Use them all the time. Why does anybody think they got dropped?

    Maybe if we get one or two thousand of us to call and ask about them over the next month, they'll change their mind and bring them back!

    Because I've spoken to both Elation and ADJ, who as far as I know were the only people who sold them, and they've both discontinued them. I think it's unlikely that they actually manufactured them, so I was hoping someone else was now selling them.

    Anyone know what's inside them? I'm sure it's not purely resistive.

    It's basically a small switching circuit that kicks in to insure the voltage is at 0 volts as the waveform crosses 0. With LED loads, they go open-circuit near the end of the voltage cycle which leaves a residual voltage on the output. Also, there is the matter of leak voltage from the firing circuit. Since this all happens at a very low voltage, there is very little power that needs to be dissipated to correct the problem. (unlike a ghost load which is there throughout the waveform.) I started to reverse engineer the circuit, but got distracted and never got back to it. Now I don't know what I did with the remains :eh:

    I know why people know they've been dropped. Sorry, poor wording of my question. What I was curious about was the cause of the dropping. Lack of sales, legal issues, safety issues, what?

    It seems that the business model of a lot of the imported product is that unless something has fantastic sales, they drop it and move on! It probably sold well, but not in the volume that would make it "fantastic." This new business model drives me nuts! Use to be a model of anything stuck around for a few years. Now, all products appear to get "replace" every year. "Oh, that's discontinued, it was last year's model." :wall:

    Currently my day job is season based product development and works in the cycle of deciding what products to carry over from the previous season and what products didn't sell well, drop them and replace with something new.
    In home furnishings that makes sense. With monolithic companies buying entertainment companies, I guess they're starting to follow that same obnoxious cycle.
