Can this be powered by 12 V DC (without the transformer)??

I will speak from my experience. NOTE: THIS IS NOT A MANUFACTURER SUPPORTED OR RECOMMENDED MODE OF OPERATION!! MAKE SURE YOU KNOW WHAT YOU ARE DOING!!! I had the same problem: existing 12VDC with inline wireless dimmer. I checked the construction of the lamps, they are built simply as 4 1W LED's in series, without a current limiter or constant current source. I measured the voltage of the white adapter (~12V) and the current (~250ma). These measurement are consistent with an earlier measurement made on this type of LED (3,3-3,5V forward voltage). Considering the above observations, I used 3 of these LED lamps without the white converter, in parallel, fed by my existing 12V 5A power supply: current consumption ~0.5A yielding a total power of 6W for 3 lamps. It was clear to me that this will work well in my setup, more so when after adding my 12-24 wireless LED controller in series with the lamps (my wife prefers to dim the LEDs to 40%). Bottom line: works perfectly without the white converter, using my 12VDC power supply and the inexpensive wireless LED dimmers available on line. Also: the light hue is a perfect match to the incandescent bulbs they replace, without the greenish tint of some earlier white LEDs. Will update in a few months.

Hello, sir, sorry, this is a dimmable bulb, if you install it without our special driver, it cannot be dimmed normally.

Yes, any 12VDC power source of 1.5A or more. I'm using one as a cordless portable work light powered with a 12V/4Ahr NiMh battery pack.

Yes it can be used with any 12 V source of power. But however it is not bright enough for what I needed

any 12 volt dc power source i would use at least 1 amp http://www.amazon.com/Wall-Adapter-Power-Supply-12VDC/dp/B006GEPUYA/ref=sr_1_1?ie=UTF8&qid=1425654988&sr=8-1&keywords=12+volt+dc+transformer

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

Hi Daniel: Mine got broken on first attempt to use it. It looks pretty neat, that's it. As far as I remember it, no, it does not have other way to power it. I think that the only way would be using somehow a 12v battery, or transforming 120v AC to 12v DC.

It needs a 6 volt, 300 mA power supply. The one that came with mine expects 120 volt AC at 60Hz and has the US 2 prong plug. So it probably won't work without a transformer, but you can probably find a replacement with the same output voltage for cheap.

Nope but you can purchase a transformer very cheap that reduces 120 down to 12 volt

You could, but I think they have another model that is specifically designed for DC... If I remember correctly for voltages up to 24vdc... I wouldn't use one that is rated for 12 vdc exactly, just for safety margin.

As it comes No, you need to buy a 110v to 12v converter and then u can use it

No... 12 volt DC only ( used on auto battery or 12 volt lawn light system).

No. The unit works on 120 Volts Ac. If you want to run it off 12 Volt DC , you would need to purchase a DC to AC Inverter that converts 12 Volt DC ( from a battery) to 120 Volts AC. There are much cheaper ways to do this.. Just look for color LEDs that operate on 12 Volt DC... Hope this information Helps.

No, you don't need to buy a 12 volt power supply. The camera comes with a 12 volt power supply.

No, this goes the other way (120V->12V). You need an inverter that goes from 12V->120V.

The panel can supply 12v dc. If your device can charge off of this voltage, you would be ok. Not sure how long it takes to charge though.

Short answer is "no". There are two wires coming out of the unit that you can basically connect to the terminals of a 12V battery (I used a car battery). You'd need to get a 12V power supply that plugs into the wall and hook it up to that if you wanted non-battery power.

Yes, 12V output plug in transformer is used. An in-line (on cord) ON-OFF switch is pre-assembled.
