Here is another tank at the low end of the light range. This time I used the "cut and paste" commands to copy the form, and deleted some redundant stuff.

PAR DATA COLLECTION

Aquarium size: 20 tall, 24" x 12" x 16"

Type of light fixture AND reflector: power compact, flimsy mylar reflector

Number of lamps, bulbs, or tubes, and wattage: 1 power compact, 65w

Age of lamps, bulbs, or tubes: 3 months

Other information: Coralife fixture and tube, 10,000K

Distance from light fixture to substrate: 20"

PAR VALUES MEASURED AT SUBSTRATE: 16

Comments: There is a very thick background of vallisneria which blocks some light. Using the old watts per gallon rule, this is high light (3.25 wpg!). Now I know why nothing will grow on the bottom of this tank except moss.
