The Osram Oslon SSL80 series holds a special place in the history of horticultural lighting. About a decade ago, these LEDs were the absolute gold standard for indoor growing. Back when the industry was just making the serious transition to LED technology, Osram’s 660nm (Hyper Red) diodes were the ultimate choice for both commercial greenhouse operators and DIY enthusiasts. They were highly respected for their unmatched reliability, thermal performance, and a tightly focused 80-degree beam angle that easily penetrated dense plant canopies without the need for secondary optics.
To keep up with the rapidly evolving demands of the agricultural market, Osram introduced a major generational update to their 660nm line in early 2017. The older, truly legendary model—marked as the Oslon SSL80 LH CP7P—was officially phased out to make way for the new generation: the Osram Oslon SSL80 GH CS8PM. This transition was a significant milestone, allowing engineers to upgrade their grow lights using the same footprint but with better performance.
The shift from the LH CP7P to the GH CS8PM brought noticeable improvements in radiant flux and overall efficacy (µmol/J). The new chip was capable of delivering a higher photon output while producing less heat. Although today's market is highly competitive and flooded with modern, highly efficient mid-power SMD packages (like the 3030 and 3535 formats), the Oslon SSL80 series remains an iconic part of LED history. These were the heavy-duty chips that proved LED grow lights could outperform traditional HPS systems, paving the way for the modern horticulture lighting industry.
