Please note Emperor Aquatics Ultraviolet Lights come in both 3" diameter housing (for maximum UV performance), and a 2" diameter housing (for reduced initial cost). Both are great products and even use many of the same "Replacement Parts".
The 3" diameter body provides a much higher degree of performance - known as the SmartUV Series.
The 2" diameter body - known as the SmartUV-Lite Series.
Please note which Ultraviolet Light and or Replacement Parts you are looking for. Please be sure sure you are ordering what you want - please call us if you have questions.
