A MR (multifaceted reflector) is a light bulb manufactured like halogen bulbs made from different electronegative particles. These bulbs were initially designed to be used as slide projectors but now it is used in residential areas and in retail Madison Bowey Capitals Jersey , track and display lighting. These bulbs are used for various applications like bicycle or motorbike headlights, ceiling lighting or as desk lamps etc. Halogen bulbs or fluorescent lamps designed as multifaceted reflectors are symbolized as MR and their diameter is mentioned with that like MR16 led. Common lamps include MR8, MR11 and MR16. These lamps are available in the market in multiple sizes and shapes. Construction of MR16 led includes a base of bi-pin GU5.3 standard with Halogen bulb blended with glass reflector. Reflector is normally of 2 inches and this reflector has a modest size than incandescent reflector bulbs that were available before MR16 led. Reflectors are available in multiple beam angles ranging from narrow to wide usually from 7-60 degree and that’s why they restrain direction, scattering and spreading of light. As the name reflects these are multifaceted reflectors so they are significantly used for soft fall-off and sharp fall-off to the elucidated area. Various coatings are used on lamps according to the requirement. These coatings include aluminum coating, platinum coating, dichroic coating and others which allow electromagnetic waves reflecting visible light and reducing heat effects. Dimmers and light fixtures are used to modify the brightness of lamps. However, color coatings alter the temperature and luminosity. MR16 led lamps are efficient and produce less heat than incandescent lamps and that’s why famously used in residential areas for lighting and also used in homes. Life time of these lamps is reduced with shocks and vibrations which can be improved by using electronic transformer to maintain dimming, stabilizing electricity and shock resistivity. MR16 led lamps are similar to MR16 halogen lamps. These lamps use electronic transformers which are blended with led transformers in permanent designs with different combination of light, colors, beam angles, lengths and competence, power and widths. Led lamps don’t use multifaceted reflectors for beam width control. Quality and temperature management of these lamps are different. MR11 and MR16 led lamps use natural looking colors like visible light and produce 25.5 lumenwatt. Halogen lamps provide more brightness than led lamps and are less
