Here's a head to head comparison between the Florawave P85FS2.3 and the GE LED Grow Light for a common grow shelf configuration.  Very few LED grow lights publish any specifications and this was one of the few models with available specs.  Here's the assumptions:

• Light suspended 2 feet above shelf.  Shelf is 4 feet long x 2 feet wide.
• PPFD of 90-120 µmol m⁻² s⁻¹.  This would be considered optimal for most carnivorous genera and high light orchids.
• Average of a 14 hour photoperiod (12 hours winter, 16 hours summer, 14 hours spring/fall)
• PPF output within 8% (180µmol s⁻¹ GE vs 196µmol s⁻¹ Florawave).
• Electric cost of $.15/KW.  (average cost in the USA.  Can be 2x or more in Europe)
• Air conditioning removes heat generated from the lights for the warmer months (half the year).
• Fluorescent bulbs are replaced every year.

RESULTS: The Florawave P85FS2.3 is cheaper initially and provides a 30% operational cost savings by year 5 while producing 8% more PPF.  Furthermore, the grow environment would be a cooler overall local environment with the lower heat output of the high efficiency LEDs. (see Thermal Considerations for more discussion on this).
