Here's my .02 FWIW,
I have been using some similar bulbs, although not the "twisty" ones. I got
these at WalMart, they are GE brand, screw-in type CF. I have had two over a
5.5 gal with DIY co2 for about 6 months with great results. I don't think
that they are really bright enough to use over any larger tank, maybe a
10gal, if you use about 4 bulbs. As I have no practical experience with
driftwood, I will leave your other question for someone else. Hope this helps
a little.
