tungsten lamp
C1technical
Definition
Meaning
An incandescent electric lamp whose filament is made of tungsten.
A term historically used to distinguish incandescent bulbs with tungsten filaments from earlier carbon-filament lamps; also used in technical contexts to specify the metal of the filament.
Linguistics
Semantic Notes
This is a compound noun. While 'tungsten lamp' is historically accurate and technically precise, in contemporary everyday usage it is often superseded by more generic terms like 'incandescent bulb' or 'filament lamp'. It emphasizes the material composition of the filament.

Learning
Memory Aids
Mnemonic
Think: 'TUNGSTEN' sounds like 'TONGUE-STEN' - imagine a lamp with a glowing metal tongue (the filament) inside.
Conceptual Metaphor
LIGHT SOURCE IS A CONTAINER (of tungsten, heat, and light).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'lamp' as 'лампа' in the sense of a table lamp ('настольная лампа'). In this compound, 'lamp' refers specifically to the bulb/light source itself ('лампа накаливания').
Common Mistakes
- Using 'tungsten lamp' to refer to any modern light bulb, including LEDs or CFLs.
- Confusing it with 'halogen lamp', which is a specific type of tungsten-halogen lamp.
- Incorrect spelling: 'tungston lamp', 'tungstun lamp'.

Frequently Asked Questions
Not exactly. A halogen lamp is a specific, more efficient type of tungsten lamp that uses a halogen cycle to redeposit evaporated tungsten back onto the filament.
They are highly inefficient, converting most of their energy into heat rather than light. Regulations in many countries have phased out general-service incandescent lamps in favour of LEDs and CFLs.
Yes, but availability is limited. They are often sold for specialist applications (e.g., ovens, photographic lighting, certain scientific equipment) or as 'rough service' industrial lamps, not for general home lighting.
Its extremely high melting point (3422°C), which allows it to be heated to white-hot temperatures to produce light without melting.
