Hobby UV-B Quick test
With this test, you can easily and quickly see whether your source of UV-B rays continues to radiate them. To test this hold the card approximately 5 cm under the lamp and wait 10 seconds. A part of the card will change from white to purple, depending on the intensity of discolouration you can tell the strength of your UV rays. According to the manufacturer, this card can be used up to 500 times. Warning! Replace your UV-lamp at least yearly if not more often, this card should be used as an indicator to do so.
