"Reverse Cube Tap"

What they are wanting to do, is what the gear I posted is used for, when it comes to stage lighting. They just want to do it in a hack sort of way, which can lead to disaster.

Unless you have a relay or some type of protection built into your circuit, there is nothing stopping a person from walking over and flipping on the other power switch.

If they want something more robust, they can go with a lighting controller http://www.pssl.com/Lighting-Control

Hi Gregg - I yield to your expertise, I've never done stage lighting. That double pole double throw switch is essentially a manual version of the relay you are referring to.

No, it is not. Unless the OP install is permanent, which is doubtful, a good setup is not going to use light switches as controllers. After a while, you start introducing noise into your system, when the contacts of the light switches start getting dirty.

I have seen setups that they have basically built a panel with a bunch of light switches controlling a lighting circuit that was just a bunch of outlets. When you see how they did it, it shows how cheap the person that did it actually is.

Buy 2 lights, or make sure your insurance is up to date!!!

There is no safe way to do this, which is why you can't buy these parts! One light with 2 male plugs is bad ANY way you try to power it! People don't generally understand power flows both ways. Turn one on and the other will become hot as well. You'd needs a custom made box with some relays and other parts. The light only gets power from one outlet and switch. The other outlet/switch would simple trigger a couple relays to pass the main power in thru a flasher relay.

I also do "stage lighting" at a rather high level and the first box linked wouldn't do anything helpful, its a box of relays. He'd get the same effect with the double throw switch. Also with a suicide plug you don't always get 240v. In the same room he'd probably still only get 120v. There are safe ways of combining power sources. We do this for very high level events so we have true redundant uninterruptible power.

Buy 2 lights!

Thanks for the advice all, it appears my method of achieving this effect was... misguided to say the least. To clarify a few things the first control box listed is half of the function i needed, and this is a setup intended for mobile use as part of a DJ rig. I ended up with this:

system, which includes a chaser pack with steady on modes (and also includes dimming and DMX abilities useful for future upgrades). I was originally thinking simply: 2 functions, 2 control means, hence two plugs, but I can see where this could quickly turn into something troublesome ( 120v + 120v = 240v = BAD; unplugged hot male plug = BAD, guessing this is where you guys got the term "suicide cord" from...)

In any case thanks for all the help!
