MR is the designation for a multifaceted reflector (MR) light bulb which has multiple small facets, this reflector gives a soft edge to the area illuminated by the bulb. Common MR (multifaceted reflector) bulb sizes are MR8/MR-8, MR11/MR-11,MR13/MR-13 and MR16/MR-16. MR (multifaceted reflector) bulbs come in a variety of base configurations, the most common ones being G4,GU5.3,GX5.3, GU7, GU10 and BA15d. Voltage ranges for MR (multifaceted reflector) Halogen light bulbs range from 6 Volt to 240 Volt.MR bulbs are commonly available in a range of color temperatures from 2700 Kelvin to 7000 Kelvin. MR bulbs are made by a wide variety of manufacturers and are suited to a variety of applications that include track lighting, recessed lighting, task lighting, pendant lamps, landscape lighting, retail lighting and fiber-optic light sources. MR bulbs come in a variety of beam spreads denoted by the following:  VNSP (very narrow spot): less than 8 degrees, NSP (narrow spot): 8-15 degrees, SP (spot): 8-20 degrees, NFL (narrow flood): 24-30 degrees, FL (flood): 35-40 degrees,  WFL (wide flood): 55-60 degrees, VWFL (very wide flood): 60 degrees or more.
