    The 100-point score model

    Every product is judged on the same five buckets, but what earns those points still depends on the category.

    Decision pointWeightWhat it covers
    Safety30 pointsUV control, flicker behavior, eye-safety guidance, and practical comfort under repeated use.
    Performance30 pointsWhether the output or treatment claims hold up under category-appropriate measurement logic.
    Usability20 pointsWhether the product can fit a realistic routine instead of looking impressive only on a landing page.
    Transparency10 pointsHow clearly the brand explains its claims, limitations, and testing assumptions.
    Build quality10 pointsDurability, stability, thermal management, and signals that the product can survive long enough to matter.

    The weighting is intentionally conservative. Safety and credible performance matter more than exciting marketing or luxury positioning.

    Deduction trigger

    Hidden measurement context

    A product loses trust when it gives impressive-looking output claims without distance, protocol, or workflow context.

    Deduction trigger

    Weak safety language

    Products lose points when they rely on comforting words like safe or non-UV without explaining the basis for those claims.

    Deduction trigger

    Routine mismatch

    A device loses credibility if the promised use case looks unrealistic once setup, comfort, or session burden are considered.

    Methodology principles

    These are the rules that stay consistent across the site, even when the category-specific scoring details change.

    Use this framework in compare

    We score by category logic

    A good SAD lamp, a good acne device, and a good red-light panel are not judged by the same raw metric.

    We punish missing context

    Claims lose weight when they hide distance, session logic, or the practical limits of the product.

    We care about routine fit

    If a product cannot fit a believable daily or weekly habit, it should not score like a top-tier option.

    We separate affiliate support from rankings

    Commercial relationships do not change the scoring model. Methodology is the product and has to stay public.

    Product sourcing

    How products enter the review system

    Products can enter through editorial research, recurring buyer interest, or category coverage needs. The important thing is that the same trust logic gets applied after the product arrives.

    Commercial independence

    Affiliate support does not change the ranking model

    The site may earn commission from links, but the score model stays public and unchanged. The methodology has to survive scrutiny or the recommendation should not exist.
