I have several of these tubes to sell for my son. They are new, never in service!! He THINKS they are Digital/Analog Light Sensors but doesn't know the exact name of them as he has never installed any. I am hoping that a LOOKER will help me out here!! The specifics of the tubes are: length 13 inches , width of the tube is 1 3/8 across the light probe end with a 9/16 by 1/2 inch ground slot at the light end. The light is 5 3/4 inches up the inside of the tube. The stainless male end is 3/8 inch with 4 screws. In the center of that end are two tiny holes in porcelain or plastic for the measurements of the light. There are 3 small set screws around the bolt end of the tube. |
