    • Superior performance. Detailed explanation by the author here: https://www.reddit.com/r/osugame/comments/5rpq1q/lightbulb_gamingfriendly_flux_alternative/ CaptaPraeliumMar 2017 Disagree   Agree
    • Very user friendly, open source, not skeptical like f.lux Guest • Apr 2017 Disagree   Agree
    • + Free & open source + Adds the feature of setting your own sunset and sunrise times, which the f.lux developer(s) did not want to add + Access to the keyboard/mouse logging hook MSCTF.dll can be declined without affecting functionality except for the ability to configure quick-keys - Occasionally crashes when denied a permission by comodo HIPS, but nothing so regular that it gets in the way of use. Guest • May 2017 Disagree   Agree
