Brief history:

Conventionally, the MR11 bulb was a halogen lamp filled with a mixture of halogen and inert gas that gave the lamp superior longevity over other standard bulbs. By comparison, the MR11 provides compact and powerful lighting.

The “MR” in their name stands for “multifaceted reflector.” This refers to the angular facets surrounding the filament in conventional bulbs. These facets were covered by a highly reflective coating, providing powerful lighting and precise beam spread.

The “11” in “MR11” refers to the size of the bulb being 11/8 inches (35mm), with other common sizes including MR8, MR13, MR14, MR16, and MR18.

How they’re used:

MR11 bulbs see wide use in a variety of lighting applications. Many 12-volt fixtures have been designed to utilize MR11 bulbs with their distinctive two-pin bases. While they see some niche applications as diverse as bicycle headlights to slide projectors, they’re most frequently found in designer lighting fixtures that fall under several common uses such as track lighting, task/desk lighting, pendants, and landscape lighting.

Why you want them:

Our LED MR11 retrofit bulbs are more efficient, versatile, and last longer than conventional halogen MR11 bulbs which operate at incredibly high temperatures and can cause severe burns with direct contact. Our MR11 bulbs eliminate this issue by operating at low temperatures.

EmeryAllen bulbs are compatible with most magnetic and electronic LED-compatible transformers, along with most MLV and ELV dimmers.

When you choose an MR11 from EmeryAllen, you’ll save considerable energy compared to conventional halogen bulbs. More than that, you’ll also get as much as ten times the expected life from our bulbs. There is no compromise in the compact size, versatility, and superior light output that you expect from an EmeryAllen bulb.
