ISH150 v2 BR testing
Welcome to our ISH150 v2 BR fixture test.
Today we are testing the ISH150 v2
Specifications:
- 256 x Samsung LM301H cri 80 SM bin
- 16 x Samsung LH351H V2 Reds
- 120w output
- Dimmable from 15w-120w
- IP65
This is 256 LM301H and 16 LH351H per Linear PCB
System Power is 120w output ran off a Meanwell XLG 150 M AB
Test equipment used for measurements:
- 1m Integral Sphere f(sphere testing)
- Light Scout (PAR testing)
- Asence tek Lighting Passport Spectrometer (spectrum analysis)
- Spectrum Genius Software (spectrum analysis)
- 2ft x 2ft silver mylar lined grow tent (environment testing)
Scenario & Objectives
objective: confirmation of efficiency and output from lighting fixture
Steps
- Sphere test Lighting unit to ascertain PPF , Umol/J and lm/w
- In depth spectrum analysis with the lighting passport and spectrum genius
- Create PAR map for average PPFD figures.
- 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.
