Congratulations! As others have pointed out, the bubbles are probably
oxygen. This means your plants, are happier, and that their happiness
was till now being limited by the low lighting.
Now that the lighting has been upgraded, your tank is most likely in a
transition phase to a new equilibrium where growth may be limited not
by lighting but by some other factor such as nutrients. You may then
find that the oxygen bubbling slows down. (Re the subject line, IMO,
more lighting does not necessarily imply more bubbles of oxygen).
You'll then have a new challenge on your hands - figuring out what to
do next. This is the sort of thing that keeps me interested in aquatic
gardening. It is still an art more than a science to me.
