Any maximum voltage specs on this led? I tend to burn out led bulbs if they can only 12v maximum and not a volt or two more. Thanks

Hello,it can works well with DC 11V-DC 13V ,but maybe become very hot More than DC 13V and become short lifetime,so DC 11.5V- DC 12.5V is the best input voltage ,thanks!

Hey Donald this is Mark, I have used these bulbs now for seven months with no burn outs. I think they are rated for 12v to 24v. They use about 3 watts. Good Luck Mark.

12volt led bulbs can be used inside anywhere the line voltage is 12 volts. 12 volt bulbs should never be used on household (110 volt in US) circuits.

I bought one bulb at Lowe's; it obviously was a 12 volt. I have tossed the old lamp, and bought a new one. End of story.

Most led's like this will run at a varying voltage. Usually this style will work with 4~18 volts at least. They may run slightly dimmer but it will most likely be not noticeable. If you would like i can go hook mine up to a 6v DC power source and see how they act. ( i bought them from here, decent lights, not the best of quality, wire isn't copper and a very very small gauge. I soldiered my connections because i was worried about the wire just breaking off without the insulation on it.

Hello my friend Ernesto, Kindly note that the input voltage for this downlight should be 100v-145v. It's not in 12 volt. If you want to get LED lights in 12V, I would recommend you to consider MR16 LED lights, which are in 12 volts. For more details, you're more than welcome to contact Lemonbest freely. We're always here for your help. Nice day. Regards Lemonbest

I'm not sure what that gadget is. I have mine running off 12v DC and they're fine. To illuminate a room, I have 3 of these bulbs in a cluster and they're great. Just using one was too little, using two was "almost" ok. Three is just right. I've had mine since about last May and (I have 6) they've been great, still working. My concern was "will they burn out after turning them off/on a few times", but no, they're terrific. Perhaps the LED technology is better than incandescent.

Dear Jia Liu, Thank you for contacting us Saicoo. No problem, the input voltage of this LED lamp is 110~240V,and the working/output voltage is DC12V. If you have any question, kindly please contact us, we will answer you at first time. Best Wishs Customer Service Saicoo

Yes... You can use two CR123 batteries or one 18650 battery. The led will operate on a range of voltage from 3.7v to 7.4v or slightly higher controlled by its built in circuitry.

I have several of these units and have had no problems. I suggest you use a voltmeter to measure both the input voltage (should be about 12V) and the output voltage (voltage should go from about 0V to 12V as you adjust the knob from full dim to full bright. If no input voltage, check the power supply. If input voltage OK, but no output voltage, first check that you LEDs are working by connecting directly to the 12V power supply; If LEDs lite OK, dimmer is bad.

You would have to check with the manufacture co. I would only use this bulb with 12V DC. It says AC 12V, but I do not know of a source for 12V AC current. Hope that helps.

12VAC is delivered to the socket; that's normal after being stepped-down from 120VAC. Internally, of course, LED's use DC -- so, there's some righteous rectification going on inside that big old light-bulb.

This is a wonderful light and I am so pleased with it, but I cannot answer the voltage question. Good luck with your move!

I have no way of knowing, the bulbs that were sent to us we for 110, they don't sell 12v. Would have been nice to know that up front,, so much for advertising the correct product. We kept the 110 v and they all started to fail after a few weeks, we ended up sending them all back and never did get a refund from these people. Amazon however took care of us just a couple weeks ago. Don't buy from this Amazon retailer.

I would say no, it will not work with 120 Volt AC current in your house. Anything designed for 12 V will probably burn out when exposed to 120 or 240 Volt household current. The LED's and the insulation on the wiring is just not designed to handle that sort of voltage. That said, these bulbs are fantastic with 12 V DC current (like you find in your car, boat, or RV). It is extremely bright and well made. I use mine as a lamp/lantern with a solar powered portable power pack that I built in a suitcase. Being able to use standard light bulb fixtures with 12 V DC is great.

Hello, there's customer not measuring voltage use high voltage and damaged the bulbs ,DC12V Bulbs Burned when last long time input high voltage , we received some Burned bulbs so have to add a notice to recommend, some new RV over 13.5v or 14V ,can select our GRV brand AC or DC 12~24V LED bulbs if not sure the input voltage,thanks!

while this particular part does not specify max wattages, similar parts specify 45w per socket ... as led bulbs are likely to be far below this i don't see any problems (i'm sure the manufacturer is simply trying to be clear that this part is NOT intended for high-wattage incandescent bulbs - and as these parts have been available forever - and as fairly bright LED bulbs are a recent development, the ad text probably has never been updated)

I have the bulb and it is stamped 130V. Wikipedia says "In the United States[3] and Canada,[4] national standards specify that the nominal voltage at the source should be 120 V and allow a range of 114 to 126 V (RMS) (−5% to +5%)." (http://en.wikipedia.org/wiki/Mains_electricity). However, I have a BSEE, and I'm confident that in an ordinary household lighting application, the bulb will work fine on a nominal 120V circuit, as it does in my house (where it lights up the inside of a dog made from a gourd :-).
