Florawave vs. T5HO Fluorescent (High PPFD grow shelf application)

Here's a head to head comparison between Florawave P85FS2.3 and T5HO Fluorescents for a common grow shelf configuration.

  • 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 1.5% (199µmol s⁻¹ vs 196µmol s⁻¹).
  • 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 more economical by the end of the first year.  After 5 years, the cost savings is nearly double!  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).
