MR16 Halogen Bulbs

What Should You Know Before Choosing MR16 Halogen Bulbs?

MR16 Halogen Bulbs are the regular size of light bulbs that can be used in both residential and business settings. They were originally designed for slide projectors and throw lights in a flood or spotlight pattern. Today it is easy to buy MR16 Halogen Light Bulbs online in both low-voltage and line-voltage versions.

The halogen bulb's size and shape are indicated by the designation MR16. MR stands for the multifaceted reflector, which gives the bulb its distinctive cone shape and reflects light as a spot or flood from the front of the bulb. The number 16 represents the bulb's diameter in eighth-inch (3.175 mm) units, suggesting that it is 2 inches (50.8 mm) in diameter. Smaller MR11 and MR8 halogen bulbs are available in addition to MR16 halogen lamps for more specific applications.

A Quick Glimpse of MR16 Halogen Bulbs

MR16 halogen bulbs, like other halogen lights, have a tungsten filament inside a pressurized halogen gas compartment. Because of the way it lights when an electric current travels through it, tungsten is the same substance used in the filament of typical incandescent bulbs. Tungsten evaporates off the filament of a conventional bulb until it is too thin to maintain a current. The halogen gas in a halogen bulb allows the tungsten to burn at a higher, brighter temperature while reducing evaporation, extending the filament's life over an incandescent bulb. Low-voltage MR16 Halogen Bulbs are predicted to last 3-6 years when used continuously.

Because they need different current requirements and use a socket that is distinct from that used by incandescent floodlights and spotlights, MR16 halogen bulbs cannot be used interchangeably with incandescent bulbs. MR16 Halogen Light Bulbs are typically 10 or 20 watts, and 12 or 24 volts require a low-voltage transformer to convert regular household electricity to low-voltage. They usually have a GU5.3 base with two pins. Line-voltage MR16s have a twist-and-lock base and can accept 120 volts of electricity.


The purity and intensity of the light produced by halogen lights are one of its main features. In addition, they last longer than incandescent bulbs. In general, low-voltage MR16 Halogen Bulbs are slightly more energy-efficient than incandescent spotlights. It offers a whiter light that is pleasing to the eyes. Except for the transformer, the lamps are smaller in size. These are some of the reasons today still people in different parts of the world prefer to use this halogen bulb.
