Must this item be plugged in and powered to work? or is the power plug strictly just for the 4 LED lights?

Yes! There is much going on in there creating AC magnetic fields as well as DC fields. There are several electro-magnets (4 as I remember) that are powered from a bank of electronic coil drivers that are driven from 4 IC circuits. I have not attempted to work out the details.

It must be plugged in. it's an electromagnet it needs the energy to create an electromagnetic field to push the floatable magnet up and away from the base magnet. It is very inyeresting to watch but don't be surprised if every nut case you show it to touches it and makes the two magnetic slam together-scratching and denting the base unit. There is a rubber cover for the floating magnet and I suggest keeping it on when you show 'anyone'...it saves some of the dents and scratches. Good Luck!

Yes. What you're doing is giving your outlet and on off switch. When it's turned on, the switch will light up green and the outlet will be powered.

It doesnt plug into either... It has a round plug that you need a Kinamax AD-LCD12 LCD Monitors 12V 6A 72W AC Adapter Power Supply which is what I have to run the lights. A dimmer like Inline PWM 12 Volt 2 Amp Dimmer for LED Strips with DC Jack by Ledwholesalers , 3318 isnt a bad idea either.

Yes you plug it in, no need to have an electrician hard wire a light for you. It works very well.

You cannot turn the light off unless you unplug the product because the light is supposed to let you know that power is going through the item. If the light is off while plugged, that means there is no power.

You do need power. I ran mine from a lightbulb adapter. It is WiFi for the connection to the Internet. If I remember correctly you need to set it up first via a wired connection so you can tell it your WiFi network name and password.

Mine is plug-in although I suppose it could be easily hard wired. These are the most beautiful lamps. People always comment on them. I highly recommend them.

Mine just plugs in. I put it as my closet lighting. It's very pretty an looks like real glass once it's hug an lit.

This is just an LED strip with a +/- lead on it. You should probably wire through a fused circuit that gets power when you want it to. Some 12V accessories have power all of the time, some with key, etc... I have mine wired through the interior lights circuit so they come on with them. I made sure it was a fused circuit because I had one of these short out and melt wires.

That's what I've got it plugged into. Works great (for the power consumption - I only have a 300W supply)!

No, you must have 110/120 volt power going to it. We replaced old light with this one so we just used the same power connections.

Once it is plugged in, the unit is off (meaning no LED will light up) unless turned on. When in that situation, LED will automatically power on during power failure. If it is not plugged to the wall outlet, it will not do any thing once it is power off.

This devise works by plugin in outlet, if your main light is connected to outlet then only this will work, otherwise not.

You can just plug in. I changed my entire ceiling light bulbs with LED ONES.

hello, the included power cord is just used to power the battery charger. It may reduce the lifetime of the light if power the led light.

Hi, theres just 1 power cord so you cant switch lights... Plug is two pronged.., hope this helps..

The power connectors on this are specifically intended to be used inside a computer case. It does not have a USB or two/three prong wall plug. The lights take a 4-pin molex connector (like a case-fan). If you got an external adapter to that then this might work with another power source (like USB or a wall plug).
