1. A lighting arrangement for general lighting, comprising:
a light source capable of emitting visible light suitable for general lighting, the visible light being white light;
a radiation source capable of emitting radiation in a predetermined spectrum, wherein the predetermined spectrum is in a range 760-1400 nm; and
a driver circuit capable of providing a first driving current that is pulsed;
wherein the lighting arrangement is configured to provide the first driving current to the radiation source but not the light source; and
wherein, in use, the light source is configured to emit at least 250 lumens,
wherein a peak emission power of the radiation source receiving the pulsed first driving current enables a power density of 0.4-50 mW/cm2, measured at a common average distance of between 0.2 and 5 m from the radiation source.
 
18. A lighting method comprising:
providing a light source capable of emitting visible light suitable for general lighting, the visible light being white light;
providing a radiation source capable of emitting radiation in a predetermined spectrum, wherein the predetermined spectrum is in a range 760-1400 nm;
supplying a first driving current that is pulsed to the radiation source to generate the radiation in the predetermined spectrum;
wherein the first driving current is not supplied to the light source; and
wherein, in use, the light source is configured to emit at least 250 lumens,
wherein a peak emission power of the radiation source receiving the pulsed first driving current enables a power density of 0.4-50 mW/cm2, measured at a common average distance of between 0.2 and 5 m from the radiation source.
