This LED spotlight bulb is perfect for track lighting, recessed lighting, desk lights, display case lighting, trade show lighting, or outdoor fixtures with weatherproof housings. The MR16 (GX5.3) bi-pin bulb has 4 LEDs and emits 400 lumens of natural white illumination. The multifaceted reflectors evenly display a 30° spot beam pattern and eliminate the sharp contrast between illuminated and non-illuminated surfaces. A GX5.3 bi-pin base allows for easy plug-and-play installation in weatherproof housings. The energy-efficient bulb uses only 4 watts of power; an incandescent bulb with comparable light output would consume 35-40 watts. This LED bulb has 12V AC/DC operation and is designed to last 30,000 hours—25 times longer than incandescent bulbs. Price per bulb.
