A lighting device is in the form of a handy portable lighting device (1) for taking photos and videos underwater. The lighting device (1) comprises a water-impermeable pressure-retaining housing (2), at least one power supply element (16), elements (17) for controlling the operation of the device (1), a multiplicity (24) of light emitters, and at least one device for measuring the spectrum of ambient illumination in the form of an RGB sensor (6). The multiplicity (24) of light emitters comprises at least three light emitters (3, 4, 5) with various spectral characteristics of the light being emitted. Each RGB sensor (6) is formed by a minimum of three sensors (7, 8, 9) for measuring the level of illumination. A means for controlling a change in the emission of the light emitters (3, 4, 5) on the basis of information obtained regarding the optical spectrum is in the form of a programmed controller (15). Furthermore, the sensors (7, 8, 9) for measuring the level of illumination of the RGB sensors (6) comprise separate coloured light filters (10, 11, 12) and are capable independently of one another of sensing light from the ambient illumination and transmitting information regarding the levels of illumination of the red, green and blue components of the light.
