This part of IEC 60598 applies to luminaires for cold cathode tubular discharge lamps and similar equipment, operating on a no-load rated output voltage over 1 000 V but not exceeding 10 000 V, mainly used for general lighting, for indoor or outdoor applications and for supply voltages up to 1 000 V.NOTE In Japan, the output voltage of 15 000 V is acceptable.It covers luminaires incorporating luminous-discharge tubes and supply units, of fixed orportable type, supplied by high, mains or ELV voltages by transformers, inverters or converters.This standard does not cover luminaires for luminous-discharge tubes operating at rated voltages not exceeding 1 000 V
