do these work with 12 volt or when plugged in 120 volt
181647
These bulbs are for use with a 12v or 24v system only, they are not for use with a 120v system

They work with 12 v in rv fluorescent lights, less heat and 70 percent less battery drain

I only wired them up to 12 volt in my motorhome. Had four fixtures with two bulbs in each. All were wired to one circuit. Found with all eight on they were not bright enough. I tried pulling one bulb out of two different fixtures. They worked great. Have one set with two on a circuit and another with four, Those work great. I was going through 6-8 of the old flouresant bulbs a year. The oldest ones in our motorhome are two years old now. Have not had to replace any. Just be careful with too many on a circuit. Have no idea if they will work with 120 volts. Manufactures website should tell you that. I only wired them up to 12 volt in my motorhome. Had four fixtures with two bulbs in each.

the model I bought is only suitable for 120 volts, not sure if they have others that might work for you

Yes, they plug right in and then you have to plug into 110 outlet. works good for the money

the ones I have bought came with the low voltage transformer that plugs in. Transformer/rectifier 120volt ac to 12volt dc

They do require 120 volt ac. I would guess you could find a power inverter that could allow you to be more mobile.

I placed these in a trailer that is 12 Volt. I'm not sure how that translates to 24 volts or even if that works.

Hello they work fine on any 12 volt adapter, with the correct amps output I think I am using a 1amp transformer

I'm not sure if they're still packaged with them, but they should have down voltage adapters that drop them down from 12v to I think 7v, a more tolerable speed if you are powering these through a 12v plug.

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.

They are 12 volt DC, just tie them into the positive and negative side of your battery or switch. You can use a cigarette lighter adaptor.

that is correct. if you connect them incorrectly nothing will happen. the voltage output will be one or two volts. if you connect them correctly you should get 18 volts. good luck.

Yes, you can safely plug these into any voltage from 120-240. You may need an adapter for the plug, as it is an American two prong.

Yes they do I have mine wired into an outlet that works off a switch , 110 v

120volt. that have outstanding sound, and are very comfortable. well worth the price.

These are 12 volt. I've never heard of any 18 volt system (?). Are you thinking 24 volt? It won't work on a 24 volt system.

No, these are pure 12 volt dc. They will not work correctly with an ac source..

I purchased these to replace line voltage (120V) halogen 50 watt GU-10 bulbs. My fixtures are 120 volt. I believe they would also work in fixtures with transformer built in (12V - 24V) but can't confirm cause I don't own any of this type. Hope this helps.
