2. The LEDs tested are not the "warm white" (1500-2500K) commonly used as replacements for incandescent bulbs in the US. They're the "blue white" (>4000K) ones, or pure blue or pure green at specific wavelengths.
With those constraints, it's an interesting result. It does not mean you need to run home and rip all the lights out, though.
1. 6000 lux is a _lot_ of light.
