Beware of words unspoken, and actions left undone you’ll keep. Your own path you must seek, for the river time is unbroken.

  • Most LEDs are based on a “blue pump”, which means the chip produces a lot of intensity in the blue wavelength range. Color temperatures are produced by adding more phosphor to the chip surface. The phosphor only allows certain wavelengths of color through, and the more phosphor added means the LED will appear warmer in color. More phosphor means more expensive though, which is why lots of LEDs are produced in the 7 to 5k range. Even when adding more phosphor to the chip and having a warmer color temperature, there is still blue light being produced and that can impact your sensitivity. Companies such as BIOS Lighting produce chips that don’t use a blue pump. Long story short, it’s a really complicated field that is long overdue for multiple layers of government regulation.
