Recommended Methods for Measurement and Testing of  Electromagnetic Radiation Sources for Plant Growth and Development

This document describes methods for measurement andtesting of electromagnetic radiation sources, bothpassively cooled and actively-cooled, with a spectralrange between 280 nm and 800 nm, used for plant growthand development. These methods are necessary to obtaininformation about device characteristics and long-termchange behaviors. This document is intended to coverLED as well as non-LED sources such as Incandescent,Fluorescent, High Intensity Discharge (HID) such as HighPressure Sodium (HPS), metal halide (MH), or othersources used for plant growth and development.
