SnowHeart said:By "all glass" hood, I'm assuming you mean the company "All-Glass"?
Actually, I'm not sure what company makes it. I'm sorry I used the term "all-glass". It's simply a glass hood rather than the standard type of plastic hood that comes with many aquariums. The light gets quite hot and wouldn't fit on my plastic hood so I bought the glass one...I believe from Drs. Foster and Smith. I may be wrong though.
Again, it works great. My green cabomba is flourishing in my tank with that lighting. Good luck.
