Overview
EN 2240-101:2011 is a CEN product standard in the Aerospace series that specifies the required characteristics for lamp, code 404-02, an incandescent lamp intended for aerospace applications. This standard defines dimensional, electrical and optical parameters, marking and designation rules, and references technical and test-method standards to ensure interchangeability, safety and predictable performance in aerospace electrical equipment and systems.
Key topics and technical requirements
The standard sets precise, verifiable characteristics (see EN 2240-101 for full figures). Key technical topics include:
Electrical ratings
- Nominal voltage: 28 V
- Nominal current: 0.024 A
- Nominal power: 0.672 W
Optical and life characteristics
- Nominal luminous flux: 1.9 lm
- Colour temperature: ≈ 2 060 K
- Rated life:
- Static with d.c.: 1 000 h
- Dynamic with d.c.: 500 h
- Static with a.c.: 1 500 h
Mechanical and geometric
- Bulb appearance: Clear
- Light centre length (LCL): 7 ± 0.75 mm
- Filament form: CC – 2F (special filament)
- Mass (per 1 000 units): 1,5 kg
Cap / base
- Specified as GX2.54, referenced to IEC 60061‑1 for cap dimensions and interchangeability.
Designation and marking
- Designation format example: LAMP, INCANDESCENT EN2240-404-02
- Lamps and packaging must be marked with the international code number as indicated in EN 2240‑002 unless space is insufficient.
Usage with other documents
- To be used together with EN 2756 (test methods) and the EN 2240 series technical specifications (EN 2240‑001 and EN 2240‑002).
Applications and who uses this standard
EN 2240-101 is intended for stakeholders involved in aerospace lighting components and systems, including:
- Aerospace OEMs and avionics manufacturers
- Component and lamp suppliers for aircraft and spacecraft
- Design and test engineers specifying lamp performance and interchangeability
- Procurement and quality assurance teams verifying compliance
- Maintenance, repair and overhaul (MRO) organizations replacing approved lamp parts
The standard supports consistent procurement and reliable performance where a defined incandescent lamp (code 404‑02) is required for aerospace electrical systems.
