This halogen MR16 is a little unusual because of the voltage, it's designed to operate in a 24 volt lighting system and is usually a track lighting situation.  Like all halogen capsule bulbs, they are filled with a special gas that actually rebuilds the filament and provides longer average lifespan than normal incandescent bulbs. Halogens come in different shapes and sizes for various different uses.  The MR16 24 volt halogen is the one that has a 2 inch reflector with a silvered (dichroic) coated which is usually faceted.  They have a bipin base which pushes into the socket and then there is usually a holder in the fixture or sometimes they are out in the open.  MR16 lamps put out a light that gives a good color rendition to anything you're lighting. This is especially useful in retail showrooms, where color is important to make merchandise look its best.

Halogen light bulbs should not be touched with your skin as the oils can react with the glass. If they are touched, the life span of the bulb will be greatly reduced and sometimes you might see a bubbling of the glass. In case you ever do touch a halogen light bulb, wipe it thoroughly with a soft cloth. Bulbs that are covered, like the PAR and some of the MR16 24 volt halogen light bulbs, are okay to touch, since you are not touching the actual bulb but a heavy, thick glass that covers the light bulb.  Most commonly, they are put into an enclosure, but be aware of touching a halogen capsule itself directly, it's not a good idea.  The MR16 lamp is low voltage in most cases, but there are some that are made with a line voltage.  If you have MR16 24 volt halogen light bulbs in your home or business, then you want to make sure of several characteristics when replacing them.  You need to make sure that the reflector opening is 2 inches, verify the operating voltage of the lamp and the pin spacing of the bulbs themselves.  A typical MR16 24 volt halogen has a pin spacing at 5.3 millimeters.  It's also important to get the wattage of the lamp which is clearly marked in most cases.

In summary, halogen light bulbs are available in a variety of sizes, and can be used, among many other things, to replace standard incandescent light bulbs. Of course, you will need fixtures that will have the correct equipment for the MR16 halogen bulbs.  The equipment will have 24 volt transformers and there will be wattage limitations for the bulbs as well.  You'll be happy with the results as they will emit a whiter, brighter light that is considered by a vast majority of people more desirable than regular light bulbs.  We have a large inventory of halogen bulbs for nearly every type of light fixture in the field.  If you need help identifying a MR16 24 volt halogen bulb, our customer service representatives can help you determine what you have.
