So the main want for this suggestion is due to the excess blue light in the spectrum, lack of deep red, IR and NIR wavelengths, the flicker associated with less than ideal rectification or pulse width modulation driving the leds and the non-linear waveform it puts back onto the power grid. Ok, then those are the areas that need addressed which can be done with a changes in product design and emissions requirements. We don’t have to go back to incandescent to achieve that.
- Include IR emitting LED chips in full spectrum lamps. UVB 298nm band for the ideal vitamin d precursor production in small quantities.
- Use constant current drivers to maintain steady voltages and currents to keep the LED in an on state so flicker rate is very low or non existent.
- CRI index of 96 or better to maintain as close to natural sunlight with no huge peaks in any one range as possible.
- Include Optical sensor or internal clock synced to the Naval Atomic clock ( receive only, no wifi, zigbee or anything else that adds microwave emissions ) to shift lamps over the course of the day to match daylight color temperature to maintain circadian rhythm. Can be time shifted for night shift worker alertness if needed.
** Correct the non-linear waveform distortions on the input power created from rectification. This will improve operating costs and efficiency on all equipment connected to the grid. This is currently a major problem with LEDs and a number of non-linear loads today adding unnecessarily high harmonic currents everywhere.**

Helpful tips
Using programs like flux on your computers and devices to make the color temperature warmer reduces blue light. But your eyes also need red, nir and IR wavelengths for proper functioning and health.
