Mains-operated luminaires

Lamps containing free metallic sodium (e.g. low-pressure sodium vapour lamps) are not permissible. This is valid in general, i.e. not only a requirement for increased safety - e -, but for all types of protection. [Pg.207]

1 Lamp types suitable for application in increased safety - e are pointed out in bold type. This table contains a selection only of lamps with a wide range of rated power. So far, this table does not claim for completeness [Pg.210]

2 For application in increased safety - e tubular fluorescent lamps shall be of the cold starting type fitted with single-pin caps (type Fa 6 according to IEC 60061-1). These lamps do not need a starter [Pg.210]

5 The very poor colour rendering property of low pressure sodium vapour lamps is due to the narrow-band emission of the Na lines (at a wavelength of 589.0 and 589.6 nm). Low pressure sodium vapour lamps are generally not within the scope of the standards for explosion protected luminaires [Pg.210]
