I am looking on upgrading my lights to either the 160w black python made by Pacificsun Pacific Sun ?Black Python? 160W CREE LED BT EX ? Master Unit Pasific Sun USA or the 24" AquaIllumination http://www.reefgeek.com/lighting/LED_Lighting/AquaIllumination_LED_Light_Systems/24_inch__2xModule_LED_Light_System_w!_Controller_by_AquaIllumination. My tank is the 50g artisan by cadlights, I currently have a 90w black python unit on it but I want some leds with a controller built into the lights themselves since my 2009 version does not have one. I would appreciate any feedback anyone has on which one to go with, Thanks!
