The MR16s exclusive Thermal-Breeze convection airflow system ensures the bulb stays cool, and allows it to achieve high LPW, up to 78 lumens per watt. The MR11 provides the perfect amount of light, and a smooth, even beam spread, for accent lighting and specialty applications. LED PARfection Mini Reflectors replace 20-50 watt halogen bulbs bulb using less than 20% of energy typically required with halogen, and lasts 3 times as long as the average halogen bulb.
