Will they last with a 12v A/C transformer (Landscape lighting)?

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

Low voltage landscape lighting is DC. That's why you use a transformer... it converts the 110 volt AC current into 12 volt DC. I bought an AC lighting fixture and wired it up to my Malibu transformer. It works fine and I have no reason to think it will not last a long time.

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.

I have an electrical engineering degree but have changed career years ago. Unfortunately, technological knowledge has slipped. However, I gave some thought concerning any potential issue if I were to use a low voltage transformer (AC of course) to power these lights. I suppose powering them with with an AC transformer may cause more degradation and shorten the life of the bulbs but other than that, I could not come up with any reason on why they won't work. So, I bought eight to put into my two lamp posts and they seem to work fine with the transformer as a power source. I'm not sure if running the lights with a DC source would produce more lumens but with my transformer, four bulbs in one lamp post still seem dark, definitely not the claimed 75W equivalent (someone already claimed that he measured the power consumed to be less than 5W instead of 9W). However, for my purpose with the lamp posts being decorative, the lumens produced seem adequate as I do have other light sources, if needed. Concerning your question of will they last, I don't expect the degradation to cut the life of the bulb by half but have no data to back up my claim.

I think the product spec is wrong. They will probably work on either AC or DC. If they were DC only they would never work as landscape lights, which are always 12 volts AC. Amazon should correct the title line.

First you have to ask the manufacturer if those are dimmable lights. If so you will have no problem the transformer.

I put a set on a dimmer and have had no problems without a transformer. Had the lights for several months now.

I like these lights a lot and I do think you will get 5 years my only issues is the transformer life. I bought 3 sets and so far so good I keep them plugged in all year round. Going on year 2 so far

Any low voltage transformer will work.. I bit of warning. If you live in an area that gets a lot of rain (like Central Kentucky) be prepared to replace a lot of bulbs. The fixture looks good, but isn't waterproof.

Yes, I used it for my outdoor Malibu lighting which is 12 volts. They actually are lasting longer than the Home Depot brand. Can't go wrong.

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.

I have them running off a 12 VDC battery in a vehicle, which is around 13.8 volts DC. If you use a 12 volt DC power supply it will work. MAke sure the output current of the power supply is sufficient to power to lights. IN other words, do not use a very small plug-in 12VDC power supply. Use one that is at least the size of a normal men's wallet. If you use too small of a power supply it could overheat the power supply. THese lights work fantastic. Theyve been on my vehicle for over a year now and continue to work flawlessly.

As long as they can take 12V DC power it will work fine. Depending on the light you may or may not need an inverter.

You will need a 120 volt a/c to 12 volt dc converter. You will also have to solder the connection to the lights.

Steve Horvath asked the question specifically about the 12VDC version of the light. LED Wholesalers sells a 12VDC, and a 120VAC version of the light. As long as your low voltage landscape lighting system can supply 12 volts DC (not AC), and can supply at least 10 watts of power, then yes this light will work fine.If, however, your low voltage system provides AC power instead of DC... then no.If your low voltage lighting system is 12 volts DC, make certain that you buy the 12VDC version of the light.

These are 12VDC and draw about 0.25A at full brightness. A 30W transformer should be sufficient.

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.

You need a low power transformer like this Paradise GL22300 300-Watt low voltage Transformer for outdoor landscape lighting (Ground shield, Light sensor, Weatherproof, A/C) plus wire. This is just one part of a bigger system. Will not work by itself.

Per the description, this bulb is 10-30 volt DC. If your landscape lighting is DC (working off of a battery), it would work. But if your lighting plugs into a household plug, it is AC and you will need a bulb that runs off AC power.Use the search for led bulbs for landscape lighting. There are some that are 12V AC that might work. I don't know what kind of base your lights take.

I am using this transformer to run some outdoor landscape lights.....using low wattage bulbs but this segment of lights has a halogen and several incandescent bulbs.....installed in water proof box with electric eye.....been hooked up for several months now
