A compact multifaceted-reflector format used for precise accent and display lighting.
MR means multifaceted reflector. The number 16 indicates a nominal diameter of 16 eighths of an inch, or 2 inches.
Track heads, landscape lights, display cases, galleries, hotels, restaurants and precision task lighting.
MR16 describes the envelope, not the base or voltage. Versions may use straight-pin GU5.3-style bases or twist-lock GU10/GZ10 bases and may operate at low voltage or mains voltage.
Technologies represented in this library: LED, Halogen.
Available base types: GU5.3, GU10, GX5.3, GZ10.
| Technology | Common wattage range | Typical lumen range | Common colour temperatures | Common voltage options |
|---|---|---|---|---|
| LED | 3.5–10 W | 250–800 lm | 2200K, 2700K, 3000K, 3500K, 4000K, 5000K, 6500K | 12V AC/DC; 120V; 220–240V, depending on base |
| HALOGEN | 20–75 W | 200–1200 lm | Approximately 2800K–3200K | 12V; 24V; 120V; 220–240V |
These are representative market ranges, not guaranteed limits. Availability varies by manufacturer, voltage, base, beam, region and product generation.
Identify the actual base and operating voltage before comparing beam angle, lumens, transformer compatibility, dimming and fixture clearance.
GU5.3 and GU10 MR16 lamps are not interchangeable. Their contacts, locking methods and typical operating voltages differ.
Important: The library describes a lamp format, not a particular product. A shared shape does not guarantee matching voltage, base, dimensions, light distribution or control-gear requirements. Confirm the fixture label and product datasheet, or ask a Bulb World lighting specialist.
