Overview

EN 2240-004:2010 - "Aerospace series - Lamps, incandescent - Part 004: Lamp, code 47 - Product standard" is a CEN (ASD‑STAN) product standard that specifies the required characteristics for lamp, code 47 used in aerospace applications. It is intended to be used together with EN 2756 (test methods) and references the EN 2240 series for technical specification, main characteristics and cap dimensions.

Key topics and requirements

• Scope: Defines required characteristics for lamp code 47 for aerospace use; dimensions are given in millimetres.
• Electrical / photometric data (from the product table):
  • Nominal voltage: 6.3 V
  • Nominal current: 0.15 A
  • Nominal power: 0.945 W
  • Nominal luminous flux: 6.5 lm
  • Colour temperature: 2200 K
• Life: Static with d.c. 1 000 h; Static with a.c. 1 350 h (dynamic with d.c. not specified).
• Mechanical / optical details: Filament form C-2R; bulb appearance clear; Light Centre Length (LCL) and full dimensional data are specified in Figure 1 and Table 1 of the standard.
• Cap:BA9s/14 (see EN 2241 for detailed cap dimensions).
• Mass: Given as 2.25 kg per 1 000 lamps (packing mass reference).
• Designation and marking: Prescribes designation format (example: LAMP, INCANDESCENT - EN2240-47) and marking requirements - lamp and packaging must carry the international code number per EN 2240-002.
• Testing: Use EN 2756 test methods and EN 2240-001 (technical specification) for full assessment.

Applications and practical use

• Standard applies to aerospace lighting components where consistent, qualified incandescent lamps are required (instrument panels, indicator lights, legacy systems).
• Useful for:
  • Aerospace manufacturers specifying replacement parts.
  • Maintenance, repair and overhaul (MRO) teams selecting approved lamps.
  • Procurement and quality assurance to verify conformance with aerospace product standards.
  • Test and certification laboratories performing verification according to EN 2756.

Who should use it

• Aerospace OEMs, avionics suppliers, MRO organizations, procurement officers, design engineers, and compliance/test labs that handle incandescent lamp specification, qualification and replacement in aircraft systems.
