Yeah, it is a white light mercury bulb, 175 watts, six feet deep...the water makes it shine green...I guess phytoplankton...when I put in a load of shiners they swim all night in a circle around the light...except when something spooks them. When they're mostly gone, I know the bluegills are back on the table. Looking forward to cheaper Louisiana crawdads for a spring treat...hoping they don't freeze to death.
