What is Multifaceted Reflector
A Multifaceted Reflector (MR) is a type of lamp that provides directional light with a controlled light distribution. Originally designed for use in 35mm slide projectors, MR lamps have found widespread use in various applications such as retail, hospitality, residential, museum, and landscape lighting.
The key feature of an MR lamp is its integrated pressed glass reflector, which plays a crucial role in controlling the direction and spread of light emitted by the lamp. The reflector is composed of facets and covered by a reflective coating, allowing it to gather light from the filament and create a concentrated beam of light. MR lamps are available in different beam angles, ranging from narrow spotlights to wide flood lamps, providing flexibility in lighting design.

In terms of reflector coating, there are two common types used in MR lamps. Some lamps use an aluminum coating, which reflects both infrared and visible radiation forward. Others use a dichroic coating, which selectively filters out heat while allowing visible light to pass through. It is important to note that dichroic lamps should only be used in fixtures that can dissipate the heat generated.

Furthermore, MR lamps are known for their compact size, allowing for smaller and more discreet fixtures compared to traditional incandescent reflector bulbs. They are often incorporated into various types of luminaires, including track heads, recessed downlights, and landscape spotlights.
Frequently Asked Questions
What Type of Reflector Is Most Common
Circular reflectors are the most commonly used type of reflector. They are particularly preferred for portrait photography as they create beautiful, round catchlights in the subject’s eyes. On the other hand, rectangular reflectors are more suitable for larger subjects that need a greater amount of light.
What Type of Reflector Can You Use at Your Home
A variety of reflectors can be used at home, including light reflectors that are typically wide, flat, and silver. However, photographers sometimes opt for white or gold reflectors. If you’re looking to purchase reflectors, you can find collapsible light reflectors at camera shops or online. Alternatively, you can create your own reflector using cardboard and aluminum foil.
What Color Is the Best Light Reflector
Silver reflectors are the most effective in reflecting light, making them ideal for situations with low light conditions. They are also great for enhancing highlights and contrast. However, it is important to avoid using silver reflectors in direct sunlight due to the harshness of the light.
What Do Different Color Reflectors Mean
Each color of reflector serves a specific purpose. The guidelines are straightforward. White reflectors are positioned alongside white traffic lines, while yellow reflectors are placed along yellow traffic lines. Red reflectors indicate to drivers that they are traveling in the wrong direction on a one-way ramp or that they should not enter.
What Two Types of Reflector Are Found Most Commonly in Theatrical Lighting Fixtures
The two most commonly found types of reflectors in theatrical lighting fixtures are the beam projector and the parabolic reflector. The beam projector is responsible for directing the light into nearly parallel beams, while the parabolic reflector is positioned in front of the lamp to reflect the light back to the parabolic reflector, effectively reducing spill.
