Eagle Star LED ESF7200B 720W Full Spectrum Foldable LED Grow Lights Wifi controll for Indoor Plants

PAR is a measurement of the intensity of light shining on a plant. It ranges from 400-700 nm which is the visible spectrum of light. If a grow light has higher and more complete PAR the plants will get better growing results.

PPF

(photosynthetic photon flux) is the total amount of PAR that is produced by a grow light each second. On grow light listings, you’ll see it as µmol/s.

PPFD

(photosynthetic photon flux density) is the amount of PAR that falls on a given surface each second. PPFD is a spot measurement of a specific location on your plant canopy and it’s measured in micromoles per square meter per second (µmol/m²/s).  

Seedlings, clones, mother plants: 200-400 PPFD

Early to late Veg: 400-800 PPFD

Flowering: 800-1200 PPFD

Photon Efficacy 

PPE refers to how efficient a grow light is at converting electrical energy into photons of PAR. On grow light listings, you’ll see it as umol/j. The higher the number is, the more efficient the grow light is at converting electrical energy into photons of PAR. The photon efficacy of ESL grows lights is 2.8-3.0 umol/j which is higher than other suppliers.

Spectrum

The light spectrum is another thing that should be considered when purchasing a LED grow light. The spectrum is essentially the colors of light that are emitted from the grow light. Different colors are made by photons at certain energy levels and are broken down into nm. The differences in the nm of a photon, or its color, change its potential effectiveness to drive photosynthesis. When growing cannabis, the plant uses more blue light when in the vegetation stage and then switches to use more red light when in the flowering stage. Although blue light and red light are needed most, cannabis plants also need other colors in the PAR range (400-700nm). UV (ultraviolet) light and IR (infrared radiation) light are also needed – in smaller amounts. Eagle star lighting led grow lights are full spectrum grow lights that cover all the wavelengths to meet different stages of the plants.

Wattage and Production

The wattage of the grow lights is a measure of energy consumption. In other words, higher energy consumption means higher production, it will help you save a lot of time and earn more money by using higher wattage-led grow lights. Especially when you buy a grow light for cannabis, it will produce 2g cannabis per wattage of the grow light by our calculation. You need four or five months to plant cannabis, now it only needs two and a half months. Now GLA720W led grow lights are for sale, and there will be more grow lights for sale to meet different applications.
