DN86 Reduced component count and compact reference design for MR16 replacement lamps using multiple 1W LEDs Silvestro Russo, October 2007 Introduction MR16 lamps are one variety of Multifaceted Reflector (MR) lamps that usually employ a halogen filament capsule as the light source.

They are used in many retail and consumer lighting applications where their size, configurability, spot-lighting capability and aesthetics provide utility and creativity.
