MR16 is a coded designation in which MR stands for multifaceted reflector, and 16 is the number of eighths of an inch the front is in diameter. An MR16 is 2 inches (51 mm), an MR11 is 1.375 inches (35 mm).
The answer to this question depends more on the type of MR16 you are using rather than the bulb's shape. The exception to this is whether or not you are using a low-voltage MR16 versus a line voltage MR16. Broadly speaking halogen bulbs, the most common type of MR16, last anywhere from 2,000 - 10,000hrs; LEDs last anywhere from 35,000 - 100,000hrs; and metal halides last anywhere from 15,000- 20,000 hrs. These are three most common bulb types for MR16s and determine how long the MR16 lasts.
The acronym MR16 stands for Multifaceted Reflector and they are types of halogen light bulbs. They are often used as light fixtures in ceilings for kitchens and bathrooms.
From 550 to 750 lumens
Every bulb has a code to it. MR16 is short for Multifaceted Reflector with a 16/8" (16 x 1/8) diameter.... or 2".A standard incandescent bulb is an A19 (don't ask me what that code stands for... A is the shape, 19 is...??)
An MR-11 is about half the size if an MR-16.
LED MR16 is a type of light bulb. These can be purchased from Amazon and more information about them can also be found here. This information includes the price, size and voltage. Alternatively, a local hardware store would be able to provide more information about these bulbs.
Generally the lumen output of bulbs is proportional to the power used, if the bulbs are operated at their rated voltage.
You will need pliers to remove the wire strip that keeps the light in the socket, then remove the lens. Carefully remove the bulb making sure there is not power in the light then replaces the bulb and reattach the lens and wire.
If you go to this website they have free online classes on how to control LED lighting. I think you will find your answers there. Hope this helps. Gary T gtnctntxs@aol.com http://www.aboutlightingcontrols.org
No you cannot use a standard mr-16 12volt bulb as it will short right when you turn it on. They do sell them but you have to look up 120V mr-16 JCDR or JCDR-C.
My advice would be to take a different approach and use 12v light bulbs. The filament is a wire. You can purchase them in the low-voltage lighting section of your hardware store, or go to an electrical distributor. I would use a 50mr16. You can also buy a mr16 socket which can be hooked to your battery array. ** caution ** this will get very hot, very quickly so please be careful.
Halogen lamps run hotter than conventional incandescents, and as a result of their hotter filaments, emit a whiter light with more of the light in the visible range, and less in the infrared. A typical 50W halogen emits between 800 and 950 lumens.
