    Converter works great
    Installed 12 volt led lights on golf cart and needed a step down transformer to go from 48 volt to 12 volt. This buck converter did the job. Easy to install and works great. Highly recommend.

    Changed 48V DC to exactly 12V.
    I changed all my 48V lights on a club cart to a 12V led system. They work very well. And the price was right. Highly recommended.
