The whole point of the LED was that the white color provides better vision at lower luminosity. If you make it yellow, there's no advantage over sodium vapor lamps which are already very efficient.
- ScottBurson 8y agoThey would still have a much broader spectrum. Sodium vapor lights are very unnatural [0] — I certainly wouldn't describe them as "cozy" and "more human", as the author does. Plus, the low-pressure ones are difficult to distinguish from a yellow traffic light. [0] https://en.wikipedia.org/wiki/Sodium-vapor_lamp https://en.wikipedia.org/wiki/Sodium-vapor_lamp
- DenisM 8y agoI concur - I own a couple of 2300k LED lights and the light the give off is very cozy, nothing like the streetlamp.
