Other factors have to be considered for the efficiency qualifications though, such as, electrical consumption, heat output, bulb life and replacement
costs, no ballasts, etc... Also, these LEDs and computer system don't put put the full spectrum of light as other bulbs do, but rather only utilize
the most effective hues.
Another thing that makes this system good is volume of space management with vertical beds stacked from floor to ceiling, and wall to wall, making the
most use of cubic ft, minus a perimeter space for maintenance. You cannot do this with any other bulbs. Water consumption is 1/3 that of normal
systems too. So it is not necessarily the yield per watt alone, but all of these factors combined that makes it a great advancement.
