I cannot tell if this is an April Fools joke, or not. My apologies if I misunderstand... However, since I have been in this hobby for about 30 years, there are general purpose lighting and specialty lighting. Specialty lighting has never been restricted, just flows with market demand. For example, T12 tubes for general lighting are restricted, but T12 for tanning beds, incubators, fish tanks, hydro are still OK and being made. Second, look around you the next time that you go out... our local large stores like the wholesale and home improvement types use solar tubes around me and have replaced all of their LEDs with T5s... a few still have HPS or MH still. Third, people have been predicting the demise of VHOs for a long time and these are still made too, for specialty things. MH sales and production are up. In the end, you don't have to worry about T5s going away for this hobby.
