Yes. I understand you. I don't speak English better The wavelength of the LEDs corresponds to the declared one. I wanted to know about the other parameters ... I was told that they are good. I wanted to clarify from people who understand this.

If you do not mind, I'll speak English. I do not know Polish. I found these LEDs in China. These are pictures with the results of measurements on a spectrophotometer. If someone understands this, tell me, are these good LEDs? 3w 445-450nm Epileds 3w 660nm Epileds
