- It adjusts colours the way I expected it to. There is a simple and efficient gui applet (redshift-gtk) available, and it supports interesting commandline options Guest • Apr 2017 • 2 agrees and 1 disagrees
- This is open source, while f.lux wants you to download a binary and run it constantly on your system. danhaiduc • 12 days ago • 1 agrees and 0 disagrees
- In most repos. Easy to use auto adjusts to the sun. Guest • 8 days ago
- Worked immediately in Ubuntu 14.04. Not able to adjust settings yet and I wonder about RedshiftGUI but this'll do for now. Guest • Sep 2017 • 1 agrees and 1 disagrees

- Can set also brightness level to change automatically. Can set the time to change to night time yourself. bklampfl • Oct 2016 • 3 agrees and 0 disagrees
- Just used it for a couple of minutes. But it really seems to do exactly what I need! Lets you choose the time, not like F.lux Guest • May 2016 • 3 agrees and 1 disagrees
- So happy I can set my own times. In the winter the sunsets happened way to earlier in Flux, then I'd turn it off and forget to turn it back on. Guest • Jan 2017 • 2 agrees and 0 disagrees
- Has keyboard shortcut to turn it off and the computer doesn't lag while the filter is turned on. Guest • Feb 2017
- Able to set times, value of filter... More options. Guest • Apr 2017 • 1 agrees and 1 disagrees
- I can change the settings in this software to activate in 24 hours but I can't active red layer in Flux in 24 hours. Guest • Aug 2017
- A Hole Pletora of Configuration Options in comparison with F.lux, allowing setting for Daylight color, Transition Time of any user specified Duration, Full Disable of Program ( not just for a temporary specified time period ), HSB Color Schemes in addition to just Kelvin temperature profiles.

- Superior performance. Detailed explanation by the author here: https://www.reddit.com/r/osugame/comments/5rpq1q/lightbulb_gamingfriendly_flux_alternative/ CaptaPraelium • Mar 2017 • 3 agrees and 0 disagrees
- + 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 • 2 agrees and 0 disagrees
- Has minimal performance impact and can be configured to have no impact at all (at the cost of smoothness). Best choice if you are a gamer. Guest • Mar 2017 • 3 agrees and 1 disagrees
- Same features, Much Better performance (Key when playing Games or performing intensive tasks), with additional options for customization, like Hotkeys, and disabling it when using a full-screen application. Guest • Jun 2017 • 1 agrees and 0 disagrees
- Simple, lightweight and configurable. Plus open-source. For Windows it does the job. johngraybosch • Apr 2017 • 2 agrees and 1 disagrees
- Very user friendly, open source, not skeptical like f.lux Guest • Apr 2017 • 1 agrees and 0 disagrees

- It doesn't use the whole screen, only the current browser page. And the sunrise/set isn't "smart" like f.lux does with your location. Guest • Jun 2015 • 6 agrees and 1 disagrees
