As long as Hamilton produces them, they will be available. I don't think they will be banned, ever. And I think Hamilton will keep producing them for years to come. There is demand from the public aquarium sphere. This is all my opinion, without doing any "research" on the subject. I just switched from 7 years of LEDs back to halides. And I'll just ride halides as long as they are available. Hopefully for many many years to come.
