i grow in 2' x 2' boxes and use overhead lights. i want to add some 1' strip lights one to each wall and door. problem i just can't seem to wrap my head around the drivers, i started learning a few years back, and built some cobs, but have forgotten what little i had learner. i am a slow learner but i try. the strips i'm looking at are the bridgelux bxeb-l0280z-30s-1000-c-c3. i want 4 for each box. can someone give me a hand in figuring this out please.

Grow Lights should be "Sized" by Grow Area and Plant Specific Growth Stage... download/file.php?id=5049
2' * 2' = 4 sq ft * 0.093 (m/sq ft) = 0.372 m2 or ~ 0.4 m2 (sq m)
0.4 * 600 PPFD = 240 PPF (required LED Output)
240 PPF / 19.76 PPF per Strip = 12.2 Strips ( ~ 13 Strips required)

240 PPF / 2.03 PPE (LED Efficacy) = 118 Watts, ~ 120 Watts (min)
