Understanding PAR
Before we dive into the topic of the best PAR LED grow lights, it’s essential to understand what PAR is. PAR stands for Photosynthetically Active Radiation, which is the range of wavelengths in the light spectrum that plants use for photosynthesis. These wavelengths range from 400nm to 700nm, which is the blue to red spectrum of light.
PAR Measurement
PAR is measured in micromoles per square meter per second (μmol/m²/s). It’s essential to know the PAR output of your grow lights because it determines the amount of light your plants are receiving. The higher the PAR output, the more light your plants are getting, which equals more photosynthesis and ultimately higher yields.
PAR vs. Lumens
Even though lumens are commonly used to measure light, they’re not an accurate measurement for plants. Lumens measure the brightness of light based on human perception, which doesn’t consider the wavelengths plants need for photosynthesis. PAR considers the wavelengths plants need and is a more accurate measurement for plant growth.
Benefits of Using LED Grow Lights
LED grow lights have become increasingly popular among indoor growers because they offer many benefits compared to traditional lighting methods such as High-Pressure Sodium (HPS) or Metal Halide (MH) lights.
Energy Efficiency
LED grow lights are the most energy-efficient lighting option for indoor growers. They use less electricity and emit less heat, which means you’ll save money on your electricity bill and won’t need to worry about cooling your grow space as much.
Longevity
LED grow lights have a longer lifespan than traditional lighting methods, which means you won’t need to replace them as often. They can last up to 50,000 hours, which equals about five years of continuous use.
Custom Spectrums
LED grow lights allow you to customize the light spectrum to fit the needs of your plants. You can adjust the light to focus on different wavelengths to promote specific aspects of plant growth, such as vegetative growth or flowering.
What to Look for in PAR LED Grow Lights
When searching for the best PAR LED grow lights, there are a few key factors to consider.
PAR Output
The most crucial factor to consider when choosing LED grow lights is the PAR output. You want to ensure that the grow lights you choose emit enough PAR to adequately cover your grow space and promote healthy plant growth.
Wattage and Coverage Area
The wattage and coverage area of the grow lights you choose are also important. You want to make sure that the wattage is high enough to cover your grow space, and the coverage area is sufficient for your plants.
Cooling System
LED grow lights emit less heat than traditional lighting methods, but they still produce some heat. Make sure that the grow lights you choose have a proper cooling system to prevent overheating and ensure the longevity of the lights.
