There is no way out of the mountains and rivers, and the willows and flowers are bright and another village. A few days ago, because I couldn't measure the color rendering index, I felt that I had been in the laboratory for three years.

Recently, I found that the color rendering index can be calculated directly with the spectrum, and I was lucky enough to enter a very professional group chat and provide a free calculator.

It seems that what restricts oneself and makes people desperate is their own vision. So don't give up easily!

Alas! I tested fluorescence once, I forgot that I didn't turn off the machine, I drove it all night, and at noon the next day, my sister found out, and said angrily in the group, I knew that the matter was very serious, and quickly apologized in the group.

Senior sister sent me a private message at this time

"Senior brother, you are too demanding of yourself, don't live so tired, take a step back and maybe you will find a new world." I was shocked, I didn't expect her to see my depression.

I am too, I didn't understand that day, until I was tired and had a nosebleed, washed it off, looked up and saw the sky of Tibetan orchids, and the green poplar trees took a long breath, and I realized that I had been chasing time, and time sometimes waited for me very slowly.
