About MR Bulbs

Multifaceted reflector bulbs (or MR bulbs for short) are designed with built-in pressed-glass reflectors that allow them to direct light at a precise angle. This makes them ideal for applications where directional lighting is of the utmost importance. Since MR bulbs were originally designed for slide projectors, they have a smaller base than standard incandescent reflectors, which makes them the bulb of choice for compact directional lighting applications such as bike lighting and modern projector lighting. Today's MR lamps are available in 10- to 75-watt power ratings (150-800 lumens).

Sizes and Brands to Meet Your Needs

Here at BulbAmerica, we proudly carry a wide range of MR bulb sizes to meet directional lighting needs large and small. As with most flood lights, MR size is denoted by a number in the bulb's name. This number specifies the bulb's diameter in 1/8-inch intervals. For example, MR16 lights are 16/8 or 2-inches across. We carry MR8, MR11, MR13, MR14, MR16, and MR18 light bulbs. Designed and manufactured by some of the industry's top brands including Philips, GE, Osram Sylvania and our very own in-house manufacturing division, the MR bulbs in our inventory here at BulbAmerica are designed for superior performance and durability in directional lighting applications of all sizes.
