Halogen MR shape bulbs provide a controlled beam of white light perfectly suited to museum, gallery, retail and residential track and accent lighting. Available with cover glass for UV protection and for color filters. The small form factor and 12V circuit allows for unlimited creative installations while minimizing the visual impact from larger 120V light bulbs.
Halogen MR Frequently Asked Questions
What are the benefits of MR shaped light bulbs compared to PAR or BR bulbs?
MR16, MR11, and MR8 shaped light bulbs are low voltage, bi-pin halogen reflectors that come in a wide variety of options and wattages.
"MR" stands for multifaceted reflector. MR bulbs were originally developed for the projector industry but later found widespread use in applications such as track lighting.
The main advantages of MRs, compared to PAR, R or BR type reflector bulbs, are the following.
- Small size
- Whiter appearing light, 2850K - 3200K
- More precise beam control
Of course, substituting them for existing 120V PAR, R or BR screw based bulbs is generally not an option. However, for new projects or remodels, it is worth considering MR16s for dynamic accent lighting or special downlight applications where the goal is to create well defined pools of light. In addition, because they are inherently directional, MR type bulbs are a very good match for LED technology.
If you are replacing halogen MR16s with LEDs, pay attention to two specifications: make sure the beam angle is close to the same, and, also try to match the "center beam candle power" or CBCP. This is a measure of the intensity of the light, which is a more important metric than overall lumens, particularly for narrow beam spotlights designed to highlight objects or art. Topbulb has over 200 variations of MR type light bulbs as well as several MR LEDs.
