As ams Osram has released on its website, the company has developed new horticulture LEDs with an outstanding combination of high efficiency, reliable performance and great value. The new OSLON® Optimal LEDs provide a flexible mix of colour and white options to meet requirements of all growing applications. Advanced chip technology and larger lenses produce the robust high performance and broad light distribution pattern required in vertical farming and inter-lighting horticulture applications.

As Osram explained, the new LEDs are available at launch in Hyper Red (660 nm) and Far Red (730 nm) colours. Deep blue and horti white versions are expected to be available in Q3 2022. The mix of colours and white provides fixture manufacturers with the flexibility to address the spectral requirements of any horticulture application.


The 3.0 mm x 3.0 mm footprint of the OSLON® Optimal LEDs makes them particularly well suited to the horticulture lighting fixtures used in vertical farms and high-density greenhouses, where tight clustering of LEDs is often necessary. In these applications, the chief requirement is to balance efficiency (photosynthetic photon flux per Watt, or PPF/W) with low cost of light (PPF/$).

As Osram furthermore explained, the new products are based on the same advanced InGaAlP Thin film chip technology as is used in the OSLON® Square family of 2mm2 die LEDs. This technology enables the OSLON® Optimal LEDs to handle high drive currents and high operating temperatures, while maintaining excellent operating lifetimes with minimal drop in photon flux over time. The 3030 High Power ceramic package is highly resistant to corrosion even when operating in harsh horticultural environments.

As Osram concluded, the OSLON® Optimal LEDs allow growers to use more direct red emitters such as the Hyper Red OSLON® Optimal LEDs to provide the red wavelengths needed for biomass growth, and to reduce the reliance on less efficient phosphor-converted white emitters to cover the red part of the spectrum. This enables growers to achieve higher overall efficiency in PPF/W.
