STEVE W On top of the light is a little switch. Push or pull the switch in then pull the half ring piece(ribbed piece behind lense cap) towards you. It slides outwards then the lense cap comes off.
TIM S Go to Ikelite's web site and click on lights then scroll to bottom of page and click on "instructions". You can download a new manual there.
