Testing Methodology

Purpose

The purpose of this methodology is to provide a transparent framework for evaluating the optical, spectral, thermal, and horticultural performance characteristics of Nano Liquid Photonic Coating™ reflector systems.

All testing procedures are designed to promote repeatability, documentation consistency, and objective measurement practices.

Test Categories

The following categories are evaluated:

Reflectance Performance

Measurement of surface reflectivity and light-return characteristics across photosynthetically active wavelengths.

PAR Distribution

Evaluation of Photosynthetically Active Radiation (PAR) delivery across a defined cultivation area.

PPFD Mapping

Measurement of Photosynthetic Photon Flux Density (PPFD) distribution beneath fixture systems.

Spectral Analysis

Assessment of wavelength distribution and spectral consistency.

Thermal Performance

Measurement of reflector and fixture operating temperatures under controlled conditions.

Crop Performance Evaluation

Observation of crop growth responses under controlled cultivation conditions.

Instrumentation

Measurements are performed using commercially available scientific instrumentation appropriate for optical and environmental evaluation.

Light Measurements

Applications:

  • PPFD mapping
  • Light intensity measurements
  • Uniformity analysis

Spectral Measurements

Ocean Optics USB4000 Spectrometer

Used for collection and analysis of spectral distribution data across relevant wavelengths.

Applications:

  • Spectral characterization
  • Wavelength distribution analysis
  • Comparative reflector studies

Thermal Measurements

FLIR E6 Thermal Camera

Used for non-contact thermal imaging and operating temperature evaluation.

Applications:

  • Thermal mapping
  • Surface temperature analysis
  • Heat distribution evaluation

Testing Environment

Testing is conducted under controlled environmental conditions whenever practical.

Environmental variables monitored include:

  • Ambient temperature
  • Relative humidity
  • Fixture height
  • Measurement distance
  • Room dimensions
  • Surface characteristics

Environmental conditions are documented during each test session.

Reflectance Evaluation Procedure

The reflector surface is illuminated using the designated light source.

Measurements are obtained according to predetermined test positions and collection procedures.

Testing objectives include:

  • Determining relative reflectance performance
  • Evaluating directional light return
  • Assessing consistency across the reflector surface

Multiple measurements may be collected and averaged to improve reliability.

PPFD Mapping Procedure

PPFD measurements are collected using a standardized grid pattern beneath each fixture.

Measurement procedures include:

  1. Fixture stabilization period
  2. Equipment calibration verification
  3. Grid establishment
  4. Sequential PPFD measurements
  5. Data recording
  6. Statistical analysis

Mapping results may include:

  • Average PPFD
  • Peak PPFD
  • Minimum PPFD
  • Uniformity ratios

Spectral Evaluation Procedure

Spectral analysis is conducted using calibrated spectrometer equipment.

Objectives include:

  • Measurement of wavelength distribution
  • Comparison of spectral characteristics
  • Identification of shifts in usable radiation delivery

Data may be presented graphically and numerically where appropriate.

Thermal Analysis Procedure

Thermal measurements are collected after operating stability has been achieved.

Measured parameters may include:

  • Reflector temperature
  • Fixture surface temperature
  • Ambient room temperature
  • Relative thermal distribution

Thermal imaging is conducted using non-contact infrared instrumentation.

Data Quality Practices

To improve consistency and reliability:

  • Equipment calibration status is verified before testing.
  • Environmental conditions are documented.
  • Measurements are recorded electronically whenever possible.
  • Repeat measurements may be collected for validation.
  • Data files are archived for future review.

Limitations

Testing results are influenced by multiple factors including:

  • Fixture design
  • Lamp type
  • Environmental conditions
  • Measurement equipment
  • Distance to target surface
  • Reflector geometry

Results obtained under one test condition may not directly translate to all cultivation environments.

Transparency Statement

Nano Grow Light is committed to continuous improvement in testing practices, data collection procedures, and validation standards.

Where applicable, additional third-party assessments, independent reviews, and expanded datasets will be incorporated into future technical publications and research releases.

This methodology is subject to revision as instrumentation, testing practices, and validation procedures evolve.
