Features: - Saving money: Lower consumption and higher brightness; 3W/5W LED replaces 30W-50W halogen spotlight bulbs, helping reduce energy costs. - Wide voltage: AC/DC 12V-24V working voltage, suitable for various applications and easy to install. - Easy to install: Standard GU4 base, plug-and-play design. Available in warm white (3000K), natural white (4000-4500K), and cool white (6000K). Provides wide beam angle and uniform illumination for enhanced brightness. - Long lifetime: Up to 30,000 hours of operational life, reducing the need for frequent replacements. Runs cooler compared to incandescent bulbs. - Wide range of use: Ideal for landscape lighting, range hoods, display cases, recessed lighting, hospitality lighting, and residential lighting. - Note: For use with 100-240V systems, a compatible 12V transformer is required. It is recommended to use an LED driver or retain 1-2 halogen lamps if using a traditional transformer to meet minimum load requirements.
