Actually at quick glance I thought it was 10 ft.
The way I figure it is this:
16 x 54w = 864w
Change 16 bulbs every 8 months = ($30 x 16) x 1.3 = $624 per year
Or
250w metal halide x 3 = 750w
4 x 54w = 216w (for actinics) = total of 966w
Change 4 bulbs every 8 months = ($30 x 4) x 1.3 = $156 per year
Change 3 bulbs every 12 months = $140 x 3 = $420 per year Total of $576 per year
Hmmm, more watts of power, higher PAR, and cheaper to run the MH.
