a) requirements to support the construction methods for new LED luminaires entering the market;

b) photobiological requirements extended;

c) more precise requirements for insulation between different types of electrical circuit;

d) other general updates and improvements. (Such as: External cables of Class III luminaires or SELV circuits in luminaires, or those used for SELV connections between parts of other luminaire types, with a maximum rated current not exceeding 2 A, may have a cross-sectional area not less than 0.4 mm2; Connection to protective earthing of the luminaire via the built-in control gear is not allowed; No values of creepage distances and clearances are specified for working voltage below SELV 60 V d.c. as the test voltage of Table 10.2 is considered sufficient; and so on)
