Ageing. Upon the request of the applicant the LED module shall be operated for 15 h and cooled down to ambient temperature before starting the tests as specified in this Regulation. 4. Specific requirements and tests 4.1. Colour rendering 4.1.1. Red content In addition to measurements as described in paragraph 7. of this Regulation: The minimum red content of the light of a LED module or headlamp incorporating LED module(s) tested at 50 V shall be such that: 780 nm ∫Ee (λ) V(λ) dλ kred = λ=610 nm 780 nm ∫Ee (λ) V(λ) dλ λ=380 nm ≥ 0.05 where: Ee(λ) (unit: W) is the spectral distribution of the irradiance; V(λ) (unit: 1) is the spectral luminous efficiency;
