FAQs

What is PAR?

PAR (Photosynthetically Active Radiation) is a region of the light spectrum (400 to 700 nm) that plants utilize for the process of photosynthesis. PAR is not a measurement or metric but defines the range of light needed to support photosynthesis.

What is PPF

PPF (Photosynthetic Photon Flux) is a measure of the total amount of light within PAR that a light source emits each second. The unit used to express PPF is micromoles of photons per second (µmol/s).

What is PPE?

PPE (Photosynthetic Photon Efficacy) is the PAR photon output of a light source (measured in micromoles per second or µmol/s) divided by the input power (Watt) to produce that light, the measurement is µmol/J. PPE does not include the photons outside the PAR range. 

What is PPFD?

PPFD (Photosynthetic Photon Flux Density) measures the amount of light within PAR that actually falls on a given surface (the plant canopy area) each second. The unit used to express PPFD is micromoles of photons per square meter per second (µmol/m2/s).

What type of grow light do you offer?

We offer CMH and LED grow lights.

Are your CMH and LED grow lights full spectrum?

Yes.

Are your lights safe to use?

>Yes. All of our lights are UL/CUL, CE/RoHs or ETL listed
