LED Sulfide Resistance Test

Sulfide Resistance Test

There may be sulfides in the nutrient solution, and the cleaning solution may also contain it. The sulfide will make the inside of the LED black, causing the brightness and color of the LED to change, thereby affecting the growth of cannabis. To this end, we sprayed glue on the LED module and did a test.

1. Pour 254g of sulfur powder into the container.

2. Put the LED module on the shelf.

3. Seal.

4. Put it in a 75 degree oven for 22 hours.

5 14 1 1

5. The color of the LED surface has not changed. After putting it in the integrating sphere test, the brightness and color changes are also very small.
