Lighting system and control thereof

A lighting system comprising:

• a lighting device comprising at least one light emitting diode;
• and
• a lighting control device;
• wherein the lighting control device is operable to switch operation of said lighting device between a continuous mode, a primed mode, and a flash mode;
• the lighting control device being arranged to control current or voltage supplied to the at least one light emitting diode:
• in said continuous mode, at a nominal operating current or voltage;
• in both said primed mode and said flash mode, at a higher level than a nominal operating current or voltage;
• and
• in said primed mode, to throttle the current or voltage supplied to the at least one light emitting diode so that the flash mode is at a higher brightness than said primed mode and said continuous mode.

A method of controlling a lighting device comprising at least one light emitting diode, the method comprising:

• powering said lighting device in a continuous mode at a nominal operating current or voltage;
• powering said lighting device in a primed mode;
• receiving a trigger;
• powering said lighting device in a flash mode so as to emit a flash upon receipt of said trigger;
• wherein, in both said primed mode and said flash mode, the current or voltage supplied to the at least one light emitting diode is higher than the nominal operating current or voltage;
• and
• wherein;
• in said primed mode;
• the current or voltage supplied to the at least one light emitting diode is throttled so that the flash mode is at a higher brightness than said primed mode and said continuous mode.
