(6) A water activated light shall commence functioning within 2 minutes of immersion and have reached a luminous intensity of 0.75 candela within 5 minutes in salt water at temperatures of −1°C and +30°C, and within 10 minutes in fresh water at ambient temperature.

(7) A fixed light and a flashing light with a flash duration of not less than 0.15 seconds shall have a luminous intensity of not less than 0.75 candela. A flashing light with a flash duration of less than 0.15 seconds shall have an effective luminous intensity of not less than 0.75 candela.

(8) A light shall have a source of energy capable of providing the luminous intensity, or the effective luminous intensity, as appropriate, for a period of at least 8 hours.

(9) The unit and the lifejacket or immersion suit attachment arrangements shall be capable of withstanding a jump into the water from a height of 4.5 metres without the unit being damaged or dislodged or causing injury to the wearer of the lifejacket or immersion suit.
