Identifying the Wattage of your UV Sterilizer
There are two ways to determine the wattage of your UV Sterilizer. Look for the wattage amount marked in black text at the non-connector end of your lamp.
Example: "40W"
You can also measure the length of your lamp and compare with the chart below.
| 12-watt Lamp | 11 ¾ inches in length |
| 18-watt Lamp | 14 ½ inches in length |
| 25-watt Lamp | 18 ½ inches in length |
| 40-watt Lamp | 32 inches in length |
| 65-watt Lamp | 61 ¾ inches in length |
Identifying the Model of your UV Sterilizer
To determine the model of your UV Sterilizer, measure the PVC body diameter and compare your results to the three guidelines below.
| If your UV Sterilizer has a body diameter of 2 inches, than it's a SMART UV Lite |
| If your UV Sterilizer has a body diameter of 3 inches, than it's a SMART UV Sterilizer |
| If your UV Sterilizer has a body diameter of 5 inches, than it's a SMART HO UV Sterilizer |
