  • Assess the Cooling System

High-wattage lights inevitably produce heat. Without proper heat management, your grow lights can overheat, potentially harming your plants and reducing the device's lifespan. Seek out lights equipped with advanced cooling features, say, robust inline fans. 

  • Light Spectrum and Dimmability

Plants require different light spectra at various growth stages. Fortunately, today's top-tier LED grow lights often offer full growth light spectrum. An added bonus is the dimming function, allowing growers to adjust light intensity as per the plant's stage of development. This feature not only ensures customized care for plants but can also lead to significant savings on electricity bills, especially in commercial setups.
