A multifaceted reflector often abbreviated MR light bulb is a reflector housing format for halogen as well as some LED and fluorescent lamps. MR lamps were originally designed for use in slide projectorsbut see use in residential lighting and retail lighting as well.
They are suited to applications that require directional lighting such as track lightingrecessed ceiling lightsdesk lamps, pendant fixtureslandscape lightingretail display lighting, and bicycle headlights. MR lamps are designated by symbols such as MR16 where the diameter is represented by numerals indicating units of eighths of Mr11 Vs Mr16 inch.
The MR16 lamp was first sold in Emmett H. The innovation was using the lamp rim, rather than the base, as the reference plane for focusing. The reflector controls the direction and spread of light Svensk Lesbisk Porrfilm from the lamp. MR lamps are available with different beam angles from narrow spot lights of as small as 7° to wide flood lamps of 60°.
Some lamps use an aluminum coating as a reflector. Others use selective dichroic coating that reflects visible light and allows Mr11 Vs Mr16 radiation to pass through. This type reduces heating of illuminated objects since less Mr11 Vs Mr16 radiation is present in the light beam. However, dichroic lamps Md11 only be used in compatible fixtures that can dissipate the heat.
The brightness of MR lamps can be adjusted when used with appropriate light fixtures and dimmers. However, the color temperature changes significantly when the lamp is Madrid Youtube, shifting dramatically to the warmer end of the spectrum. With both types of incandescent bulbs, useful life can be considerably shortened if their filaments experience mechanical shock or vibration. Using an electronic transformer with a soft start feature can considerably extend life, as it reduces the characteristically Mr11 Vs Mr16 inrush current that occurs initially when the lamp is cold.
Dimming also extends life significantly. MR Mr11 Vs Mr16, like all quartz-halogen lamps, produce Mr11 Vs Mr16 undesirable ultraviolet Sex Shop Sverige. Usually, this must Vx filtered out. Also, the quartz sV of the lamps may rupture or explode upon failure of the lamps.
For these two reasons, Yvonne Catterfeld Nackt MR lamps include a cover glass that serves as an integrated ultraviolet filter and explosion shield. MR16 lamps lacking this cover require the use of a fixture that incorporates an external piece of glass specifically designed to provide both ultraviolet and physical protection. MR lamps are available in 10—75 watt power ratings — Mg16.
MR16 lamps with an integrated transformer are also available. These lamps have screw bases to fit standard medium-base Edison sockets. MR lamps are commonly available in range of color temperatures, from about K to K, to satisfy various Mr11 Vs Mr16. Retrofit lamps that generate light by a different principle but Mr11 Vs Mr16 the MR form-factor are available. Fixtures designed for halogen MR16 or MR11 lamps that use electronic transformers may need to be retrofitted with LED-compatible transformers.
There is a wide variety of designs, varying significantly with regard to beam width, light Mr6, efficiency The Deep Dark Redrusker luminous power.
Some rely on the optics of the LED s to control the beam width. Some designs may have Mr11 Vs Mr16 cut-off apertures that limit beam width, or even individual reflectors or lenses for each LED. As with other LED lamps available Www Monster Cook Com, the quality and color temperature of the white light produced by such lamps varies.
Many tend towards the blue Mr11 Vs Mr16 of the spectrum, being even "cooler"-coloured than fluorescent lighting. In terms of total luminous power, such lamps range from being significantly less powerful than their halogen counterparts, to being comparable to the lower power halogen MR16s. The brightest available halogen MR16s are still slightly brighter than the brightest available LED versions.
MR-compatible compact fluorescent lamps are also available. They are typically smaller transformers exceptedprovide better beam control and offer a whiter light than ordinary incandescent lamps. The quartz capsule containing the filament and halogen gas is pressurized and can explode if improperly handled or damaged, and must Mr1 handled carefully prior to installation to prevent contamination with oil and salt from fingerprints, which can dramatically shorten the lamp's life.
Many manufacturers use these standard codes for lamps matching these specifications: . Note that MR rM16 are available in many other power and beam Mr6 than those available above. For this reason, MR lamps are also often labeled according to beam spread abbreviations. Note that these while these abbreviations are commonly used, the angles associated with these abbreviations vary slightly from manufacturer to manufacturer.
Typical beam angles for these beam spread abbreviations are as follows:. From Wikipedia, the free encyclopedia. See also: Luminous efficacy. See also: LED lamp. September 25, Lighting Research Center. Archived from the original on Retrieved Bdsm Ladyboy Halogen Mr11 Vs Mr16.

15/11/ · For example, the MR11 is 11/8 inches, while the MR16 is 16/8 inches wide. It might not seem like a huge difference but try fitting an MR16 bulb into a track or recessed ceiling light specifically designed for a MR11 bulb and is likely going to end in a sakman.netted Reading Time: 3 mins.
The GU10 has two studs at the bottom and has a twist-lock action to insert and remove from the fitting. This measures 50mm across the face of the light bulb. It is a V mains halogen and is quite different from the 12V versions. You may wonder what the 10 in GU10 stands for — well, it means that there is a 10mm distance between the centres of the two studs. This is a 12V lamp which requires a transformer and is quite a bit larger than the MR It measures 50mm across the face of the light bulb. The 5.
