Will this work with a 12 volt AC fixture? I purchased some from another seller. They were for DC power and would not work in my fixture.

Never heard of a 12ac fixture. Most use either 120v ac direct or run through a ac/dc converter and output 12v dc. But to answer your question, no dc only.

These do say 12 VAC but I use them for 12 VDC and they work fine. Never tried them VAC. Sorry I can't tell you more.

They will not work on Ac voltage. A rectifier may work. You will get some voltage drop. Depending on how many feet you are running it may not affect it too bad. Won't hurt to try. You may have to add a filter cap too. 12 volt DC supply's are cheap though. I'd just buy one. You don't need a big one. Low current draw with LEDs.

i thought the same that 12-110-120 would work on either 12V or on 120 we need these for our properties in Belize that are all high volt 110 not landscape lights running on 12V after trying many this is the only one that i have found works on 110V if you find other please let me know Ostart MR16 110v Indoor LED Light Ceiling Light Bulb 4W Day White 6000k-6500k

I must reconsider my answer after looking at this a little closer. The lights do require 12vDC and not AC. There is such an adapter sold elsewhere on Amazon that can power this string. I would have to say that you probably cannot use this transformer.

These are 12V (probably AC only) If you will have transformer to 12V they will work technically. If you have an isntallation with multiple MR16s and you would like to change it to LED I would recommend to change the transformer to LED version. Otherwise it may not work or if it will work you will decrese the lifespan of the bulb (I work for LED manuacturing company in EU)

I am not using them in a dimming application, however, from the product description at Amazon:"Low Voltage: 12V AC/DC compatible; DIMMABLE when working with electronic dimmers"Electronic dimmers? I can't help you with that either.

I use a 12 v. DC power transformer. This works fine but you will need to solder the connections.

It will work on 12 or 24 volts DC.I tried it on 24 volts AC and it blew the bulb.

Ouse standard 4w 12v bulbs. However I would think any led that had the correct base and rated for 12 v yes would work. Not much help.

they are rated 7-16v ac/dc. i can tell you they worked for a short while on 12vdc, when i tested them, but when i used 15v ac mocking up the fixture, 2 fried about the 3rd time switching on. i have one working on 12vdc regulated about 5 months they have a beefy bridge rectifier internally, but it seems the ic regulator or driver is not up to the task of switched supply that comes from an unbuffered 60hz rectified feed. they would have been better off using a more traditional regulator to drive the leds

My thoughts are that they will not work with AC. They are designed to be used with low voltage (12Volt) DC lighting circuits. They look just like the normal 12 volt incandescent bulbs but have the longevity of LED.

The first thing you would need to do is determine if the existing bulbs are 12v or 120v. If they are 120v DON'T USE THESE! These bulbs are rated for 12v ac or dc. If you determine that the voltage is compatable, then it's just a matter of if they'll fit. These modules have their electronics mounted on the back, so you'll need close to 1/2 inch clearance back there.

The solar switch I have is marked clearly as 12v DC with same markings as your's, but no marking anywhere as 120VAC on it. I would believe it is intended for 120VAC use only.Order again a 12VDC unit.Mine works real well on 12VDC yard lights.Thomas Wilson

Yes - I use these bulbs on exterior landscape lighting fixtures that are on a 12 volt a/c (via Malibu low voltage transformer). You can use any normal 120 volt incandescent fixture (which takes normal "old fashioned" bulbs), add to a low voltage line and utilize these low-voltage LED bulbs. They do a great job - so far 7 months running 4 hours per night and no problems. Do not put bulbs in a normal residential 120 volt circuit.

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