Decoding LED grow lights: Beyond the numbers
Added on 06 February 2024
In the dynamic world of horticultural lighting, the hunt for the perfect LED grow light can be both exciting and daunting. With an ever-expanding market and a surge in innovative horticultural LED lighting fixtures, it's crucial for consumers to tread carefully. In 2021, an age-old phrase remains incredibly pertinent: "Lies, damn lies, and statistics." Here, we'll navigate through the maze of LED grow light choices and shed light on the numbers that truly matter.
The Beacon: Photosynthetic Photon Efficacy
As you delve into the universe of LED grow lights, you'll encounter a pivotal number - PPE, or Photosynthetic Photon Efficacy. For newcomers, this acronym may initially appear as a mark of scientific authority. Photosynthetic Photon Efficacy has been the gold standard in measuring "light efficiency" within the horticultural industry for years. However, the scene is evolving.
Deciphering the Code: The Microscopic World of µmols and Joules
A closer look at Photon Efficiency reveals that it's measured in µmols per Joule (J). Now, for many, the inclusion of Greek symbols and the mention of "Joules" might transport them back to less pleasant science class memories. The mere thought of "science talk" can trigger flashbacks of Charlie Brown's teacher - "Wah-wah-wah micromoles wah-wah-wah, photon efficacy…" But for those earnestly seeking the best LED grow light, merely comparing Photon Efficiency numbers won't suffice.
