About This

• Classifies Sunlight Exposure in Real Environments. Accurately identifies Full Sun, Partial Sun, Partial Shade, or Shade based on DLI (Daily Light Integral) levels—helping gardeners and designers optimize plant placement.
• Clear Visual Feedback. Digital display shows the daily light accumulation in mol/m²/day and directly tells you the light category—no need for calculations or charts.
• Stores up to 10 days of DLI histroy. Records up to 10 days of daily DLI readings, allowing you to review recent sunlight conditions and compare how much light a planting location receives over time.
• No Setup & Auto Start. Simply place EVO-20 in the soil at the spot you want to evaluate. The meter starts accumulating daily light automatically, making it easy to check the DLI reading and sunlight category later.
• Works with for sunlight, LED grow lights, HPS, and CMH.
• Long Battery Life & Portable Design. Ideal for patios, greenhouses, or any landscape inspection.
• IMPORTANT NOTE – HOW EVO-20 MEASURES LIGHT. This is not an instant light meter. EVO-20 measures Daily Light Integral (DLI) by accumulating light over time. When first powered on, the light value may appear blank or unchanged. This is normal. A valid reading builds gradually with continuous light exposure and is finalized through the meter’s built-in program.
