1. Different types of LED grow lights
Traditional Panels: For small spaces, traditional panels are compact in size and often include full-spectrum horticultural lighting. They are "hybrid" styles between COB styles.
Distributed: Distributed plant growth lights are panels dotted with small LEDs on a large area. Advantages for many factories, higher throughput and built-in cooling system can be obtained. Subcategories include quantum board, spider and folding style grow lights.
COB grow lights provide powerful illumination from a single light source, emitting full spectrum frequencies.
2. How do users choose the right LED grow light?
Before making a selection, users need to have a basic understanding of the basic requirements of LED plant growth lights:
Spectrum: LED grow lights mimic natural light, but unless they are full-spectrum LED grow lights, they may not have all the colors on the electromagnetic spectrum (such as a special ratio of red and blue light).
If users are growing marijuana plants from seed to flower, they should look for a combination of blue, purple (UV), red and infrared (IR) LEDs.
Heat output: To avoid leaf burn, the best LED grow lights have cooling systems such as radiators or rely on fans to dissipate heat, these systems also keep the light from overheating.
Footprint diagram: The footprint diagram refers to the growth space covered by the plant growth lamp at different heights.
2. PPFD test parameters of different heights of LED plant growth lights
Power: Contrary to popular belief, higher wattage is not the best way to assess how much power an LED grow light consumes. LEDs are designed to be cost-effective, so higher wattages may put more financial pressure on growers.
The true measurement of power comes down to how much light the plant itself needs to absorb, listed as a 400nm-700nm PAR rating. PAR stands for Photosynthetically Active Radiation, in other words it is the amount of visible light that plants use for photosynthesis.
Light Intensity: The standard for measuring light intensity is micromoles per joule, and the best LED grow lights have high PPF because they produce more photons per second.
In addition to PPFD, users may also see measurements in μmol/m2/s or PPFD (Photosynthetic Photon Flux Density). This sounds technical, but all you need to know as a grower is that the cannabis PPFD measures the number of photons hitting the surface of the plant per second.
You need to measure PPF and PPFD on the same plane at different heights to know the intensity of light at different heights.
Voltage: Often overlooked by home growers, make sure the user's power outlet can accept the voltage range of the LED grow light, especially if the light itself includes a series function.
This allows you to connect multiple lights in a given space, but consumes more power and requires wiring into the home.
Warranty/Service life: Since LED grow lights are a product investment, having a warranty can effectively eliminate worries for users and ensure that faulty parts can be returned and replaced. Also, it is better to choose a product with a longer lifespan (more hours).
