Well... I hope RLM and LGS do some tests on the lights when they assemble them to certify the wavelenght is the correct one. You can't really trust anything from China until you double-check it yourself. Imagine they send you incorrect wavelengths and you are emitting bluelight or defective or more power or infrared when you thought it was visible red, really, anything can happen. You need some quality control which I hope LGS is doing. You can get a light wavelength meter for 100 bucks.
Lot testing products is always nice, but if the light was blue it would look blue, and if the LED was infrared there would be no visible light except maybe in the near infrared there could be a very faint red that could be seen by some people as humans all have slightly different ranges of wavelengths we can see. If it looks orange it is orange, if it looks red it is red, and shade variances of each would be fairly noticeable to most people.
