16" depth has little to do w/ it..
bigger question is your "requirements" other than light quantity.
Any (well most) of the strip type LED's are fine for your output requirements.
In a sense your next question is functionality and budget..
It would be easy to suggest a say Current planted plus pro or fluval planted II.
both would give you options from low to high light..but at a cost.
Ther are others
Somewhat the same w/ a Finnex 24/7.
After that ,and more realistic (?) in pricing are
Finnex/Beamswork/other Current USA fixtures.
Like this.. good starter light though higher output than you might want.
simple stick on a timer and have it turn off/on..
Can be modified for a dimmer (simple in line splice of a cheap PWM dimmer unit)
