After the heat resistant test, we then carried out the frozen resistant test for the LED light source to prove THT-EX lighting can also be used in low-temperature environments, such as ultra-freezer rooms, cold storage warehouses, ice factories, low-temperature food processing plants, etc.
We light up the light source in water and record that if it still provided illumination from the liquid status to being frozen. Guess what? Let's watch the result together! :D
