What a 100 means for sunrise alarm clocks
A wake-up light judged on how gradually and how brightly it rises — the part with actual circadian evidence.
This score compares Philips SmartSleep HF3520 Wake-Up Light against 18 other sunrise alarm clocks only. It is not comparable to a score in another category — a mattress and a sleep mask share no attribute, so a single ranking across them would be arithmetic without meaning.
Not declared
Philips publishes nothing about durability & care, material & build. These are left out of the score rather than scored as zero — silence is not evidence of a failing. They are why the score is capped at 93 for this product.
