Armacost Lighting’s RibbonFlex Pro LED tape lighting and LED cabinet down lights operate on 12-volt DC constant voltage power and require an AC to DC transformer 12V power supply. Never connect low-voltage LED lighting directly to 120V AC household power.
Note: RV, boat and solar applications can be powered directly by 12V DC battery – a power supply is not needed.
For help choosing a power supply for white LED lighting, see this document.

White LED lighting, without a dimmer
If you are installing white LED lighting, and do not plan to add a dimmer to control brightness, choose an Armacost Lighting Standard Electronic Power Supply.
If you later decide you want to dim your lighting, you can easily add an Armacost Low-Voltage Dimmer when using a Standard Electronic Power Supply.
White LED lighting, using a dimmer
If you want to control the brightness of your LED lighting, the power supply you need is dependent on the type of dimmer you plan to use in your installation. If you are already familiar with the installation and application advantages between low-voltage 12V DC and 120V AC LED dimming, you can choose from the Armacost power supply options found below.
