  • WARNING: Do not install a 12 Volt LED light bulb into a standard residential 120 VAC socket as this will cause a short and burn out socket and bulb.


This household 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 bi-pin bulb has 9 LEDs (5730 SMD) with an output of up to 300 lumens and produces a 60° beam of warm (3000K) or natural white (3900K) illumination. A GU5.3 bi-pin base allows for easy plug-and-play installation. The energy-efficient bulb uses only 4 watts of power; an incandescent bulb with comparable light output would consume 40 watts. This LED bulb has 12V AC/DC operation and is designed to last 50,000 hours—42 times longer than incandescent bulbs. Price per bulb.

Important Notes - Please read before purchasing:
  1. Non-Weatherproof, Indoor use only unless contained within weatherproof housing or used in conjunction with weatherproofing products
  2. This bulb is oversize, please see dimensions under Specifications tab.

Nice and bright!

I love the bright-white light! So glad I changed out all the yellow lights to this beautiful white.
