If you replace the lamp and it does not work then most likely you need a new starter. Since starters are inexpensive and shipping is relatively expensive it my be a good idea to see what starter your unit uses, if any as sometimes the starting is a function of the ballast, and add a starter or two to your order. Not all fixtures use a starter. Sometimes the start function is built into the ballast. A ballast is more expensive and harder to find.

Germicidal lamps are clear with special UV transmitting glass. For use in sterilizers and air and water purifiers. This is an ultraviolet C (253.7 nm wavelength) bulb for use in sterilization, water and air purification and surface disinfection. Used in the Forming and Disinfection of Contact Lenses. Used in UV Sterilizers for Fish Aquariums and Ponds. Fixed wavelength spectrophotometer detector. Germicidal lamps allow 253.7nm UV-C radiation from the mercury discharge to pass through the glass thus penetrating and inactivating the DNA of most micro-organisms.
