A portable light or torch has numerous light emitting diodes (LEDs) (8, fig 3) each arranged to emit light of a different colour, and a touch screen interface 1 for controlling the brightness of each of the LEDs individually so as to control the colour of light emitted by the LEDs 8 in combination. Parts 17-20 of the touch screen interface 1 may be actuated to cause the light to emit light of a given colour. |
