You may need the FG-1E, FS-25 or some other starter. 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.
Occasionally a customer will have a problem fitting in a new G25T8 lamp. While the maximum overall length is 18" the lamp can be a little shorter. If your equipment is adjusted for a tight fit with a lamp shorter than the new lamp it may be difficult or impossible to install. Fortunately there is an easy fix. You will find that one of the two socket ends is adjustable. You can loosen the screw(s) holding the socket in place, slide the socket so the opening is slightly wider, retighten the screw(s), and then install the new lamp.
