Fixture Testing - ISH650 F
Fixture testing for ISH650 F
Specifications:
- 1890 x Samsung LM301H cri 80 SM bin
- 84 x Osram Hyper Reds 660nm
- 650w output
- Dimmable from 60w-650w
- IP65
Fixture has 315 LM301H and 14 Osram per Linear PCB
System Power is 650w output ran off a Meanwell HLG 600h 54B
The PCB are conformal coated to protect the LED. This gives a water proof finish.
Test equipment used for measurements:
- Light Scout (PAR testing)
- Asence tek Lighting Passport Spectrometer (spectrum analysis)
- Spectrum Genius Software (spectrum analysis)
- 4ft x 4ft silver mylar lined grow tent (environment testing)
Scenario & Objectives
objective: confirmation of efficiency and output from lighting fixture
Steps
- In depth spectrum analysis with the lighting passport and spectrum genius
- Create PAR map at 16 and 22 inches for average PPFD figures.
- Check spectrum against chlorophyll a & b / phytochrome pr & ppr
Testing:
Spectrum analysis completed at 28 inches as not to saturate spectrum analysis.
Par Maps completed at 16 and 22 Inches for more accurate data on penetration.
With each test we analyze the spectrum and data, from the overall PPFD to the individual weighted spectrums and their efficiency.
Below are the results for each test variant.
