I think Aquatic lighting is more aimed at brightness and plant growth, since its to encourage plant growth I would assume there would be some UVB aswell since the aim is full spectrum lighting to mimic sunlight.
How much Uvb output they may produce, I dont really know, I kept reef fish years and years ago before I began with reptiles.
Most lighting produces uva to various extent.
If the spectrum produced is suitable for reptiles then why not, but with the range of reptile specific lighting avail and the improving tecknology, I'd stick to those types to benifit from improving quality.
To keep my plants looking good I rotate them outside whenever possible. However Ive noticed that since I have gone to double fixtures with 6500k bulbs with built in reflectors. My plants have stayed inside longer periods without the need for outside time to recover. I believe the reflectors are helping to utilize the maximum benefit of the bulbs. I had never used any type of reflectors before as I hated the aluminum foil look on my fixures.
