The chart
below compares photon flux delivered by an array of 72 watts of LEDGrowLights and from 320 watts of fluorescent grow lights.
LEDGrowLights provide much more of the useful red and blue areas of the spectrum than the
fluorescents.
Comparison of photon flux delivered by 72
watts of LEDGrowLightsTM
(six, 10-watt R180XB and six, 2 watt B60RA manufactured by LGL Technologies
and 320 watts of fluorescent lights (eight, 40 watt "Plant & Aquarium" fluorescent
bulbs manufactured by General Electric.)
