High voltage fixutures for a low voltage system

I am designing an outdoor low voltage (12 volt) lighting system and would like to use a post light. I have not found many low voltage rated post lights. Then I got the idea to use a regular 120v post light fixture but use a 100 watt equivalent LED bulb that will not require much wattage to operate. Is this doable?

Thanks for any comments and thoughts.

Here is an example of a 12 vole Edison base (AKA medium base) 12 volt LED. It would screw into the lamp holder of a 120 volt post light but run on 12 volts. (Same site as Geo's) https://www.superbrightleds.com/cat/...,E26E27,1,448:

So, there is no reason the fixture would pose a problem as long as the bulb itself was designed for a low voltage application. I guess the off the shelf LED replacement bulbs at the local big box store that are supposed to be used to replace incandescent bulbs would not work because they are for 120 volt household systems. Is that correct?

Yes, 120 volt bulbs won't work. However you may need to include a rectifier for those to work on an AC low voltage system such as Malaboo. I'm not sure on that. They are generally intended for 12 volt DC systems.

Thank you Ray. I will look into the possible need to add the rectifier.
