Can I power line voltage lamp from low voltage transformer?

7 years ago
I’m working on my backyard and will be running low voltage lights everywhere. However, for my pier/column lamps, I can’t find many low-voltage options. I’d rather not have to run line voltage out just for those pillars. Is it simply a matter of putting in bulbs that can run off low voltage?

    I do not understand the question. What does the word "it" refer to?

    Thanks for your response. Let me restate my question. If I purchase a fixture that isn’t low voltage out of the box (eg designed to be used with a 120V bulb), can I simply use a 12V bulb instead and wire the fixture up to my low voltage transformer? Is there a way to “convert” the fixture to low voltage?

    Sorry if I am not clear. I’m new to this stuff.

    Hey Daniel,


    While using the correct bulb or integrated LED board unit would be one step of the conversion, the internal components of the fixture may also need altering. Of course, this would really be dependent on the manufacturer but, the process itself is generally not recommended. When all of the alterations are said and done, it more than likely would've been cheaper, more convenient to find a listed, professionally built low-voltage fixture that can meet your needs.


    Also, what kind fixture might you be looking for? Maybe I could direct you to one of ours or just a general style that could help you.

    Thanks Volt! I actually just spent over $2k on your site last week... unfortunately you don’t have a large selection of pier mount lights :(

    Maybe someone can help you if you describe -- in minute detail -- exactly what you're looking for in a pier mount light. If you can find a picture, even better. If you can find a picture of a 120V fixture that would do the job, show it.

    Wow, awesome!


    Some categories and styles of lights we have tended to shy away from out of a matter of DIY convenience (which we pride ourselves on with all of our products.) Essentially, there are some projects that without a doubt require tools/experience which the average homeowner is not so likely to possess (such as having the proper tools/experience to run wire through cement/stone posts or to install recessed underwater lights). But, we are indeed always working to expand our line and I would be happy to relay your recommendation to the team here.


    Be sure to let us know if you have any questions and don't forget to submit your project photos! It's always fun to show off your house after a project like LVL.

    I see your dilemma and answer will need to come from lighting pro.

    Volt, understood. I think it would be pretty cool if you did LV pier mounts though... They’re hard to find and more and more people are moving to LV systems. I think you could sell them for much more as well. Maybe a bit more challenging for DIY, but many folks, like me, are working with contractors on a bigger job and this type of install is no problem.

    My plan now is to buy a normal line voltage fixture, put in a low voltage bulb, and wire it up to my Volt slimline transformer. Fingers crossed.

    Lastly, I saw this from Cascade Lighting website:

    “Our customers often ask if we offer 12 volt post top or column mount lanterns. We are happy to answer that any post top or column mount lantern with a medium base (A19 – or Edison screw base) socket or the smaller candelabra base socket may be installed with a low voltage 12 volt system or simply alone.
    The secret is that the lantern socket solely depends on the voltage of the lamp installed and the voltage to the lamps. There is no need for a “conversion kit” to turn a 120v fixture into a 12 volt powered fixture.


    12v Post Top and Column Mount Lantern Lamp Choices

    If you are installing a lantern and want it to operate as a 12 volt system, you would first choose a 12v incandescent or LED lamp to fit the lantern socket type (medium base or candelabra). There are various wattage output options available and in stock at Cascade. The next step is to connect the lantern wire leads to the proper direct burial low voltage cable size (to fit the job) and then connect the cable to a professional grade magnetic landscape transformer. “

    Well, our transformers are magnetic and they certainly are professional grade! Glad you were able to find a light that met your needs. Best of luck with the setup!

    Arroyo Craftsman offers a lot of really cool post and column lights that can be ordered for line voltage or low voltage.


    We had a client who fell in love with a line voltage post light that uses candelabra bulbs. It took some digging but we were able to find candelabra bulbs that accept 12v power, and wired it up with the rest of the backyard lights.

    OK let me stop the madness, the answer is YES YOU CAN, the voltage is determained by the bulb. the wattage will be determined by how much space you have left on the transformer. don't be fooled.

  • 7 years ago

    parts for lights as to the sockets etc are all the same weather line or low voltage. its not fancy when it comes to medium or candelabra based bulbs.

  • 7 years ago

    if you go to an actually lighting store they will have or be able to easily get 12v bulbs.

    Thank you!!!

    add up all the wattage you plan to put on the line, and remember that the further away the last light is from the transformer the less current it will get. Most landscape lighting really doesnt need more that 10 20watts depending on far you are trying to reach. most post lights with candle base bulbs will say "max wattage" you do not want the max, if there is more than one socket, get 15 watts or less if possible because the total wattage is x3. if its a single base try only 25 watts, light goes really far at night and people often over lamp exterior post lights.
