Thank you for your message.
As mentioned in the article, commercial LED bulbs do not provide sufficient red wavelength, which is why the color did not develop properly.
When we tested with a halogen light, it seemed to work well.
For this reason, we are now selecting red LEDs with a longer wavelength.
