The LiquidLEDs 4-watt 12 Volt DC Candle LED Bulb Clear (with a B15/small bayonet cap configuration) looks just like any other candle-shaped bulb on the market. However, this low-voltage bulb is incredibly energy-efficient, using only 4 watts of electricity to generate 350 lumens of light. What sets this bulb apart is its combination of classic style and modern LED technology. With its elegant, candle-shaped design, this dimmable bulb is perfect for use in low-voltage bathrooms. To dim the bulb, a 12V DC 1-10 dimmable driver is required.
