chahahc I want to try the ABSOLUTE SERIES 99 CRI LED Technology | Waveform Lighting you mentioned before. It has the violet LED chip that @KM brought to our attention.
I have no experience with LED strip lighting, but it is a project I am looking into.
Their literature from that page:
Traditional white LEDs use 455 nanometer blue die as the underlying light source, and a dual-phosphor mix of green and red phosphors to achieve a semi-full spectrum light output.
This results in what is commonly referred to as the "cyan gap" - where there is a lack of light energy in the region between blue and green wavelengths, and an overshoot of blue wavelength energy. A close look at color rendering scores such as CRI R12 will also reveal that blue colors may appear over or under-saturated.
ABSOLUTE SERIES™ LEDs utilize a different method of producing white light to eliminate the cyan gap and blue overshoot. By shifting the underlying light source wavelength to a violet 420 nm die, a fuller, wider spectrum is made possible. This also provides energy coverage down to the nUV wavelength range.
The spectrum explanation is also strengthened in light of @KM finding that Quantum Dots can reduce LED backlight brightness associated pain.
