In June 2003 the Twenty20 Cup kicked off with Essex and Sussex deciding to each play 2 of their home matches under their lights. No other counties staged group matches under lights. This was the first time that day/night cricket in England had been played between any two counties outside of the National League and on 19 July 2003 at Trent Bridge in Nottingham Surrey Lions won not only the Twenty20 Cup for the first time but also won the very first domestic cup final to be played under floodlights.
