I am selling (2) GHL SIMU-L lightsticks. These attach directly to ports on your GHL controller and give sunrise, sunset, bluesky, moonlight and lightning storm effects to you reef! Sealed Led's dim and brighten to follow actual lunar phases as well.
Very cool effects to watch and an inexpensive add-on to your GHL controller.
See lightning effect here.
