The testing methods for LED plant growth lamps mainly include the following aspects‌:

‌High temperature and high pressure and impact test‌: Place the LED lamp in an environment with a room temperature of 60°C, adjust the input voltage to 1.1 times the rated input voltage through the voltage regulator, turn on the lamp for 24 hours and observe whether the lamp is damaged or the material is deformed by heat. Then conduct an impact test, turn on the lamp for 20 seconds, turn off the lamp for 20 seconds, and cycle 100 times to evaluate the stability and durability of the lamp‌.

‌Low temperature and low pressure and impact test‌: Similar to the high temperature and high pressure test, but carried out in a low temperature and low pressure environment, evaluate the performance and durability of the lamp under extreme temperatures.

‌Light intensity measurement‌: Use a photometer with a sensor to measure the amount of light falling on the plant surface to evaluate whether enough light is provided for indoor plants to achieve maximum productivity. Light intensity measurement can help adjust the lighting conditions of indoor plants to achieve the best growth effect‌.

‌Heat dissipation performance test‌: Since plant growth lamps are used for a long time, heat dissipation performance is crucial. By testing the LED light source directly attached to the ceramic heat sink, the efficiency of heat dissipation directly into the environment through air convection is evaluated to ensure the reliability and service life of the lamp.

‌Life test‌: By continuously lighting the lamp, observing its service life under specified conditions to ensure that the product meets the expected durability standards.

Together, these test methods ensure the performance and durability of LED plant growth lights under various environmental conditions, providing plants with stable and effective lighting conditions.
