Can you connect these to a preexisting power transformer and not use the included one?

It depends. This uses 12V AC power; many low-voltage transformers make DC power. This works with two LEDs connected with opposite polarities. When the AC changes polarity, the other LED turns on. This happens so fast you can't see it. If you connect to a DC power supply, only 1 LED will light, and it will be basically half-brightness.

If the power is the same you could. Also the connectors would have to be the same otherwise you would have to splice into them, and they wouldn't be as water tight. But it can be done.

I hard wired all these lights. Works great. No need to use the included transformer.

Yes if you are not exceeding the power of your power pack. Remember these connectors are for connecting one line to another. Lights attach to the line not the connector.

The transformer can be plugged into and gets it's power from 1 receptacle. The transformer itself DOES NOT have a receptacle.

You'll need a transformator to do so. Not worth the headache. There is a version suitable for 220 volts. Look for them

I do not see why not. Just daisy chains a number of devices if you have a transformer that is powerful enough to drive more than one connection. I don't have the specifics of what you're hooking up other than the Korg. I take it you're trying to connect a number of devices with this cord and an existing transformer. On the transformer you should have the amperage. If I was hooking up multiple devices I would worry more about that aspect. Each device will draw power and the transformer needs to be powerful enough.

Yes, they come with a nice 120-230VAC to 12VDC Adapter. If you wanted to you could connect to any other source of 12VDC. It is a great product.

NO, you can not. It's like a chain in command. If the plugs are not connected power won't run any further than the first plug on the cable.

You do not need another transformer. You can either solder wires between the joints where you cut them or buy premade connectors. I recommend the lattter

You should be able to no problem. Just don't use the small 12v transformer that comes with it.

If you have a POE capable switch/router, I believe these require 24V. If not, they include transformers that use 110V.
1239133
Yes, you can! This transformer input 110v and output 220v. The only thing you should notice is that the voltage capacity is just 100W!

other than using a transformer adaptive to you supply voltage. I would recomend you contact the manufacture direct to avoid mishaps.

Putting aside the problem of plug incompatibility, I do not use it overseas without a transformer.

They are not necessary, but I have found that the voltage feels stronger without them, even on the lowest setting. So, it can be done, but it might be too much "zappage".

You will to power there with the included AC power adapter. Each one has a separate power adapter.

I see no reason that wouldn't work. One end of the lights have a coax connector that plugs into a standard 12V adapter. The other end has two wires for connecting to another string. The second string would require removing the connector and connecting the wires to the first string. Each string will take about 20W so you have plenty of power for up to 10 strings. I would recommend soldering the wires, but that is not absolutely necessary if you make a good connection. One question - does that transformer put out AC or DC? The lights require DC.
