Different manufacturers use different product names to describe a fluorescent tubes, see below a table of the top four manufacturers and how they brand their different tubes.
As you can see above even though the main four brands identify tubes by different names/terms, it is still possible to swap one brand for another as long as you keep the wattage and length the same.
