The new development here seems to be that these are white LEDs that can be specced in terms of blue/green ratio, rather than metrics based around human vision (color temperature, tint, and color rendering index). Cree and other manufacturers have been offering horticulture-specific LEDs for some time, both red/blue and red/blue-weighted white like these. Here are some of their competitors: Samsung: https://www.samsung.com/led/lighting/applications/horticulture-lighting/ https://www.samsung.com/led/lighting/applications/horticultu...

What's the benefit of white vs narrowband leds?
- Retric 4y ago
  Benefits of white is it looks more natural for people buying/inspecting plants, think aquariums etc. Benefits of narrower band LEDs is it’s more energy efficient and cheaper, think indoor lettuce / pot farms.

    I tried using these lights when I moved my plants into the garage one winter. The light from the blue/red is so harsh on the eyes. I totally hated it. I get the zero energy wasted on the light the plants don't need/don't use, but after that I assume that the savings from using LEDs was way more than the old full spectrum hot lamps so emitting more human friendly light is well worth it to me.

      In my greenhouse I use half white, half blue/red lights. The resulting colour is not uncomfortable, and I can just turn off the blue/red lights when I want to inspect the plants in white light. To be honest though, I have no idea whether it saves a noticeable amount of energy compared to using just white lights.
