Perhaps LPR filters for fluoro lights may be effective? The white LEDs I think usually mix only a handful of wavelengths together from different phosphors to produce visually white light so filters that stop only those wavelengths might be pretty effective.
Good point, I don't know the exact wavelength of the upgraded led types but if the people who are overseeing those operations, have any idea of what they are doing, they would stick to a wavelength with amber hues/colour, and hopefully will not render LPR filter investments useless.

It's been researched that these amber wavelengths are more suited for long periods of focus for humans. Such as the old amber and green computer monitors. It was found that these monitors are easier on the eyes and are more comfortable to view.
