Features: - Energy Efficient: 3W/5W LED bulbs replace 30W–50W halogen spotlight bulbs, reducing energy consumption and lowering electricity costs. - Wide Input Voltage Range: Compatible with AC/DC 12V–24V (operating range: 10V–30V), making installation simple and versatile. - Easy Installation: Standard GU4 base, plug-and-play design. Available in Warm White (3000K), Natural White (4000–4500K), and Cool White (6000K). Wide 120° beam angle provides even, bright illumination for a comfortable environment. - Long Lifespan: Up to 30,000 hours of operation—reducing the need for frequent replacements. Runs cooler and is safer than incandescent bulbs. - Versatile Applications: Suitable for landscape lighting, range hoods, display cases, recessed lighting, hospitality lighting, and residential lighting. - Note: For 100–240V mains voltage, a 12V transformer is required. We recommend using an LED-compatible transformer or retaining 1–2 halogen bulbs to meet the minimum load requirement of traditional transformers.
