These MR11(Multifaceted Reflector 11/8" diameter) LED light bulbs are perfect replacements for MR11 type halogen bulbs. Unlike the typical 800~1000 hour halogen bulb, these LED bulbs are rated 50,000. The bulb replacing cost alone, over the lifetime of the LED bulb, will save you nearly $100. You will also save a lot of money on electricity bills. Due to the minimal heat it generates, the lamp fixture's life will be extended too. That's some extra savings.
