LED
Common wattage: 12–25 W
Typical output: 1000–2500 lm
Colour temperature / output: 2700K–6500K
Voltage: 120V; 220–240V
Notes: Visible-light reflector versions; availability varies.

A large 125-millimetre reflector lamp commonly used for radiant heating and high-output specialty applications.
R identifies a reflector envelope and 125 indicates an approximate maximum diameter of 125 millimetres. Clear and red hard-glass infrared versions are common.
Animal care, veterinary equipment, food warming, industrial drying, bathrooms and radiant-heating equipment.
The format is strongly associated with incandescent infrared lamps, although visible-light and LED reflector versions may be available in some markets.
Technologies represented in this library: LED, Incandescent, Infrared.
Available base types: E26, E27.

Notes: Selected by radiant-heat performance and application rating rather than lumens.
These are representative market ranges, not guaranteed limits. Availability varies by manufacturer, voltage, base, beam, finish, region and product generation.
Match the base, voltage, wattage, reflector diameter, hard-glass or finish requirement, operating position and equipment approval.
R125 heat lamps become extremely hot. Use only heat-rated sockets and guards, maintain clearance and protect people, animals and materials from excessive exposure.
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 requirements. Confirm the fixture label and product datasheet, or ask a Bulb World lighting specialist.
