Will these lights operate on 9VDC? Will doing so damage them?

Probably so. Although they may not be as bright. On the plus side maybe less likely to melt as mine did. Over-voltage definitely not a good idea you will let out the magic smoke that makes it work.

Yes, I tested them with a 9V battery. If you run 3 9V batteries in series you could keep them going but that would get expensive. 9x3=24 volts

They come with a small converter/transformer which is pigtailed on. I don't know what voltage the LEDS are designed to work at, but you could certainly cut off the attached transformer and wore directly to the LED unit.

You will need to buy a voltage converter. If you splice the wire and hook it up directly you WILL damage the lights.

If you are using them for an exterior light monitored by the computer the answer is most likely not, unless you add a load resistor kit like this one:

Not that I've seen but you're better of cutting them off and using LED bulbs anyways. It's just 12v nothing special.

These LEDs operate on 38-42VDC through a driver. They cannot be configured to operate on 12VDC. However, we have other products which can be adapted.

No, it is 9V, I am sure about that.The polarity is what I doubt, but is easy to check. If you pug it and the light does not turn on, it is the other choice.You cannot damage it by connecting it inverse.

No they are designed for 115v ac. If energized @ 12vdc I would expect no discernable light ourput

If they are 110v, I would expect it to work fine. Mine is connected to a single switch that controls 2 outdoor lights. They have regular bulb, but I don't see any difference, it's just turning a circuit on or off.

The lights use very little power at all. In fact I would say carrying the weight of the 9 volt would use more than running the lights off car power.

Yes, they will run off as little as a 9Volt battery though for what length of time I have not tested. A 12Volt car adapter works very well. I was also able to light them up with a 5.5Volt 200mA adapter. I really enjoy them and will be getting many more for my workshop, closets, and all over outdoors for landscape accent lighting.

The LEDs in this light operate on DC. The AC adapter/transformer is built into the unit, and cannot be bypassed.
683129
Yes. Works fine on 12vdc or 12vac. They will dim just fine with a PWM dimmer control even though the manufacturer says they don't

The lights state they are DC voltage. This transformer is is AC. They will not work.

LED lights work very differently than the older incandescent lights, where you would simply put in a 220 volt lamp. Too high a voltage would destroy the electronics inside, probably instantly.

I would think not. The ones I have are designed to run on typical computer power supply output and they have standard molex plugs. I would check with a good electrician before I tried anything like you suggest. They are really cool lights though aren't they ?

If your transformer truly outputs AC you may not want this light. It will try to run on only half of the power half the time because the rest of the time the electricity is going in the wrong direction for this DC device, that will either make it run poorly or not at all. It will also likely shorten it's lifespan. Double check your transformer for output markings if it is an AC transformer with a rectifier that outputs DC then these lights should work fine. Mine have worked well for about a year or so. **Note** They don't like water so if you do use them make sure your fixtures seal.
