Can they? Most white LEDs emit blue light into a phosphor. You are always going to end up with a definite blue spike in the spectrum.
- nullc 7y agoThere exist white LEDs that instead use a deep violet emitter which they're able to much more effectively filter out, eliminating the high frequency spike. Good luck finding them in products though.
