# The Ecodesign for Energy-Related Products and Energy Information (Lighting Products) Regulations 2021, Paragraph 2: Product information sheet


(1) An equivalence claim involving the power of a replaced light source type may be given only—
(a) for directional light sources, if the light source type is listed in Table 7 and the luminous flux of the light source in a 90° cone (Φ90°) is not lower than the corresponding reference luminous flux in Table 7, and for this purpose—
(i) the reference luminous flux must be multiplied by the correction factor in Table 8; and
(ii) for LED light sources, it must in addition be multiplied by the correction factor in Table 9;
(b) for non-directional light sources, if the claimed equivalent incandescent light source power (in Watts, rounded to the nearest integer) corresponds to the luminous flux of the light source in Table 10.
(2) The intermediate values of both the luminous flux and the claimed equivalent light source power (in Watts, rounded to the integer) must be calculated by linear interpolation between the two adjacent values.
(3) A claim that a LED light source replaces a fluorescent light source without integrated ballast of a particular wattage may be made only if—
(a) the luminous intensity in any direction around the tube axis does not deviate by more than 25% from the average luminous intensity around the tube;
(b) the luminous flux of the LED light source is not lower than the luminous flux of the fluorescent light source of the claimed wattage; and
(c) the wattage of the LED light source is not higher than the wattage of the fluorescent light source it is claimed to replace.
(4) For light sources that can be tuned to emit light at full-load with different characteristics, the values of parameters that vary with these characteristics must be reported at the reference control settings.
(5) For the purposes of sub-paragraph (3)(b), the luminous flux of the fluorescent light source must be obtained by multiplying the claimed wattage with the minimum luminous efficacy value corresponding to the fluorescent light source in Table 11.
