Scenario & Objectives

objective: confirmation of efficiency and output from lighting fixture

Steps

  1. Sphere test Lighting unit to ascertain PPF ,  Umol/J and lm/w
  2. In depth spectrum analysis with the lighting passport and spectrum genius
  3. Create PAR map for average PPFD figures. 
  4. Check spectrum against chlorophyll a & b / phytochrome pr & ppr

Testing:

Spectrum analysis completed at 18 inches as not to saturate spectrum analysis.

Par Maps completed at 18 Inches completed at

  • 12 Inches (30cm) full power 240w

With each test we analyze the spectrum and data, from the overall PPFD and Umol/J to the individual weighted spectrums and their efficiency. 

 

Below are the results for each test variant.
