New Horticultural Lighting Technology News from AMS OSLON: OSLON® Optimal Plant Lighting LED Series Adds Enhanced 640nm Red Products

June 15, 2023 - Ahmers Osram, a leading global provider of optical solutions, today announced the expansion of its OSLON® Optimal plant lighting (horticultural lighting) LED family with the introduction of a new 640nm RED LED (red) to make indoor gardening faster and healthier.

With broader coverage in the red part of the spectrum, the 640nm Red LED now joins the OSLON® Optimal product family, along with the 660nm Hyper Red (Ultra Red), 730nm (Far Red), 450nm Deep Blue LED and plant white LEDs, providing users with more versions to choose from.
For plants that need to be illuminated by a full-spectrum light source, conventional horticultural operations use 660nm, 450nm and 730nm, or a mix of 660nm and white LEDs. In contrast, preliminary research commissioned by Ahmers OSLON from the University of Washington has shown that dual red peaks (640nm and 660nm) combined with white light for plants can increase biomass levels (dry weight) in indoor growing environments.
Based on growing experience, OSLON® Optimal Red helps prevent fungal and bacterial infections in leafy greens such as basil.
The new OSLON® Optimal Red products play an important role in improving energy efficiency and reducing electricity costs for all plant lighting applications such as greenhouse top lighting and interior lighting, as well as vertical farms. It produces a luminous efficiency of 3.53µmol/J and an electro-optical conversion efficiency of 66.3%. the LED radiative flux reaches 485mW and the photon flux reaches 2.58µmol/s. the peak wavelength is 640nm and the main wavelength is 630nm.
The introduction of OSLON® Optimal Red LEDs will provide plant lighting equipment manufacturers with a more efficient and stable light source," said Thomas Grebner, marketing manager at Emmis Osram.
