- MR16 LED Bulbs for Outdoor Use : Designed specifically for 12V outdoor landscape lighting fixtures, our MR16 LED spotlight bulbs are ideal for applications such as spotlights, pool lighting, well lights, driveway lighting, and garden illumination. Important: These LED bulbs should not be used with halogen transformers in indoor setups, as this may cause flickering. - Energy Efficient 20W Replacement : Our 3W LED MR16 bulbs can effectively replace 20-35W halogen MR16 bulbs, providing significant energy savings of over 85% on your electric bill. For applications requiring higher lumen output, consider our 5W MR16 LED bulb (ASIN: B07LG7PRKL). - Warm White Light (2700K-3000K) : These bulbs emit a soft warm white light, closely resembling the glow of traditional halogen MR16 bulbs, creating a welcoming atmosphere in your outdoor spaces. - GU5.3 Bi-pin Base : Installation is a breeze with our standard MR16 size (1.97" x 1.97"). The plug-and-play design ensures compatibility with existing fixtures, making upgrades quick and hassle-free.
