The LEDs have been binned and tested to maximise photosynthetic photon flux (PPF), which determines the amount of photosynthetically active radiation (PAR) provided by a light source each second.
PAR is a key parameter used by gardeners and other operators at indoor and greenhouse farming installations to monitor artificial lighting systems.
The series offers PPF/watt measurements from 1.84 for one of the purple LEDs (with 2.5% blue), up to 2.32 for the ‘deep red’ and ‘far red’ LEDs, specified at 120mA current flow and a device junction temperature of 25°C.
Other colours available with varying levels of PPF/W, include: two further purple LED types – integrating 12.5% or 25% blue – along with royal blue, lime, and horticulture white.
Available in packages measuring 2.8 x 3.5mm, the LEDs provide a 120° light-distribution angle to deliver uniform light in greenhouse applications, and include options for single LED-driver systems, as well as multi-channel and colour-tuneable solutions.
