    4. The Measurement of Luminous Flux
    5. Nominal and rated lamp luminous flux.
    6. ‘Objective luminous flux’ means a design value of the luminous flux of a replaceable light source or light source module.
    7. The luminous flux of this gas-discharge light source may differ from the objective luminous flux specified in Regulation No 99.
