comparing lights:
-
Total Photon Flux or Photon Flux (PF) is a measurement of the total number of photons coming out of a light source per second. It counts all photon...
-
Photosynthetic Active Radiation (PAR) designates the spectrum or range of colors of light from 400 to 700 nanometers that plants are able to use fo...
-
Yield Photon Flux (YPF) is a measure of light intensity, weighted based on the light wavelength's usefulness to plants when it is the only color of...
-
It's easy to be confused by the idea of beam angle and how it can affect plant growth. Each individual diode (LED stands for Light-Emitting Diode) ...
-
Many people look for a single measurement or statistic that can be used to compare different types of grow lights. Many companies try to impress by...
-
4.5% of the total photon flux of PhytoMAX-2 lights is in the 320-400nm UV-A range. Because UV light is more energetic than PAR light, 6.6% of the t...

Yes, there is one critical change you will need to make in your growing style to maximize yields under Black Dog LED PhytoMAX-2® lights: keeping th...
-
Aren't passively-cooled LED grow lights better?
HPS, MH, CMH / LEC and other high intensity discharge lights increase in efficiency as the bulb get...
-
When you get anything warm enough it will start to give off light, and the hotter it gets, the more energetic the light gets, shifting from the red...
-
We eliminated the glass for efficiency. Every time light transitions from one material to another, such as air to glass, some of the light is lost ...
-
Our lights appear more expensive than some other LED lights, but that's because our lights have more actual power than most. When comparing the cos...

Black Dog lights don't have a color temperature, and to understand why you need to know what "color temperature" means.
The correlated color temper...
