MR16 GU5.3 LED bulbs work typically with 12 volt system. We also have a 24V DC version for optional. Retrofitted MR16 LED halogen replacement bulbs are widely applied for marine, boats, household and landscape lighting. LED MR16 bulbs come in cool white, warm white, neutral white and RGB multicolor options. We also supply dimmable MR16 LED replacement bulbs that will work with existing dimmers, which worked with halogens. Please choose a correct equal wattage and lumen output for your replacement bulbs. 12V AC LED bulbs work perfectly with wire-wound, magnetic and iron-core transformers; however, some electrical transformers may cause flickering, flashing and even damage.
