what good is 2 plain-old 8 watt fluro lights in a tank that is 16 inches
high? This is an unused tank and I want to keep a few spare plants in,
will these lights do any good?

Likely, not much good at all. If it's 16 inches high, it's what, 45-55
gallons? You may be able to keep some Java Moss in there.g

It's a 12 gallon tank... the lights are fairly bright... oh well. what if
they are on for 16 hours a day?

Low to moderate light plants would be ok. It helps to reduce the water
level a bit.....but still you should be fine... If the bulbs are older
than a year or so of continuous use, then get new fresh bulbs...more
light output. They get less bright as they age......and finally will
emit almost no light and the bulb will just glow...a bit...

I wouldn't go more than 12/day to start, any more may help algae to take
off...

Nope. Duration can't make up for intensity. Leaving the lights on longer than
12-14 hours a day will just get you algae problems.
