Recall that a unit normal vector to a surface can be given by

[ extbf{n} = dfrac{ extbf{r}_u imes extbf{r}_v}{ left| extbf{r}_u imes extbf{r}_v ight| }]

There is another choice for the normal vector to the surface, namely the vector in the opposite direction, (- extbf{n}).

By this point, you may have noticed the similarity between the formulas for the unit normal vector and the surface integral. This idea leads us to the definition of the Flux Integral. Consider a fluid flowing through a surface (S). The Flux of the fluid across (S) measures the amount of fluid passing through the surface per unit time. If the fluid flow is represented by the vector field (F), then for a small piece with area (Delta S) of the surface the flux will equal to

[Delta ext{Flux} = F cdot n, Delta S ]

Adding up all these together and taking a limit, we get

Definition: Flux Integral

Let (F) be a differentiable vector field on a surface (S) oriented by a unit normal vector (n). The flux integral of (F) across (n) is given by

[ iint_{S} (F cdot n) dsigma . ]

Note that the method for choosing the value for (dsigma) for flux is identical to doing it for the integrals described above. Also notice that the denominator of (n) and the formula for (dS) both involve ( | extbf{r}_u imes extbf{r}_v|). Canceling, we get

[ extbf{n}, dS = extbf{r}_u imes extbf{r}_v dv, du]

for a surface that is defined by the function (z = g(x,y)), we get the nice formula

[ extbf{n}, dS = -g_x(x,y) hat{ extbf{i}} - g_y(x,y)hat{ extbf{j}} + hat{ extbf{k}} ext{(oriented upward)}]


[ extbf{n}, dS = g_x(x,y) hat{ extbf{i}} + g_y(x,y)hat{ extbf{j}} - hat{ extbf{k}} ext{(oriented downward)}]

Example (PageIndex{1})

Find the flux of ( F = yzhat{ extbf{j}} +z^{2}hat{ extbf{k}} ) outward through the surface (S) cut from the cylinder ( y^{2} + z^{2} = 1, z geq 0 ), by the planes (x = 0) and (x = 1).


First we calculate the outward normal field on (S). This can be calulated by finding the gradient of ( g(x,y,z) = y^{2} + z^{2} ) and dividing by its magnitude.

[ n = frac{ abla g}{| abla g |} = frac{2yhat{ extbf{j}} + 2zhat{ extbf{k}}}{sqrt{4y^{2} + 4z^{2}}} = frac{2yhat{ extbf{i}} + 2zhat{ extbf{k}}}{2sqrt{1}} = yhat{ extbf{j}} + zhat{ extbf{k}} ]

Next, we calculate the value for (dsigma = frac{ abla g}{| abla g cdot p|} dA ). Note the similarity to the value of (n). All we need to do is find the value of (p). Because our cylinder sits with its shadow region in the xy plane, the vector normal to that region is in the (k) direction. Thus,

[ dsigma = frac{ abla g}{| abla g cdot k|} dA = frac{2}{2z} dA = frac{1}{z} dA ]

Note: we dropped the absolute value bars in the last step there because the problems specifies (z geq 0) on (S).

Now find the value of ( F cdot n ).

[egin{align} F cdot n &= (yzhat{ extbf{j}} + z^{2}hat{ extbf{k}}) cdot (yhat{ extbf{j}} + zhat{ extbf{k}}) &= y^{2}z + z^{3} &= z(y^{2} + z^{2}) &= z & ext{because the surface} && ext{is defined as } y^{2} + z^{2} = 1 end{align}]

Once all the preliminary work is done, plug them into the integral:

[ iint_{S} F cdot n , dsigma = iint_{S} left(z ight) left(frac{1}{z} dA ight) = iint_{R_{xy}} dA = area(R_{xy}) = 2].

Example (PageIndex{2})

Find the flux of (F = yhat{ extbf{j}} - zhat{ extbf{k}} ) through the paraboloid (S = y = x^{2} + z^{2}, y leq 1 ).


The flux can be described by ( iint _{S} F cdot n , dsigma ) with ( n = frac{2xhat{ extbf{i}} - hat{ extbf{j}} + 2zhat{ extbf{k}}}{sqrt{1 + 4x^{2} + 4z^{2}}} ).

Take the dot product of (F) and (n)

[(0hat{ extbf{i}}+yhat{ extbf{j}}- zhat{ extbf{k}}) cdot frac{2xhat{ extbf{i}}-hat{ extbf{j}}+2zhat{ extbf{k}}}{sqrt{1+4x^{2}+4z^{2}}} = frac{1}{sqrt{1+4x^{2}+4z^{2}}}(-y+2z^{2})]

Substitute (x^{2} + z^{2} = y ) to simplify (n) to ( -1 + frac{2z^{2}}{y} ).

Thus, the integral for the flux is

[egin{align} &int_{-1}^1 int_{-1}^1 left(-1 + frac{2z^{2}}{y} ight) dz, dy &= int_{-1}^{1} -z + left. frac{2z^3}{3y} ight |_{-1}^{1} dy &= int_{-1}^{1} left (-1 + frac{2}{3y} ight) - left (1 + frac{-2}{3y} ight) dy &= int_{-1}^{1} -2 dy &= 0 end{align}]

The total flux through the surface is 0.

Example (PageIndex{3})

Find the flux of

[ extbf{F}(x,y,z) = xhat{ extbf{i}} + 2yhat{ extbf{j}} + zhat{ extbf{k}}]

across the part of the surface

[ z = x + y2 ]

with upward pointing normal that lies within the box

( 0 le x le 3 ) and ( 2 le y le 5)


We compute

[ NdS = -hat{ extbf{i}} - 2yhat{ extbf{j}} + hat{ extbf{k}} dy, dx]


[ extbf{F} cdot extbf{N}, dS = -x - 4y^2 + x + y^2 = -3y^2 ]

The flux integral is

[ int_0^3int_2^5 -3y^2,dy,dx = -351]

f.lux is a really handy tool that allows you to adjust the colour temperature on your display. If you stare at a screen for too long, then the glare from the display begins to hurt your eyes. To start with, turning down your monitor's brightness may help you, but brightness is not the really issue. The colour temperature is what causes the problems.

Most computer screens emit a bluish light, which looks great in daytime, but it becomes uncomfortable to look at when the sun dips below the horizon. Not only can your screen become uncomfortable to look at, it can also affect your sleep patterns*.

F.lux works by calculating the approximate sunset time for your location. At sunset, your computer screen will mimic nature, gradually warming up the colours. This, in turn, blends in better with the surrounding light.

If you spend a large amount of time looking at your computer screen, then f.lux is definitely something that you should check out.

*There has been research which suggests reading on a tablet for a couple of hours before you go to sleep can delay your sleep pattern by approximately an hour.

Search our list of questions first, and if you don't find what you need, head over to our forum.

Life and the universe

F.lux on macOS

  • I have a newer 2013+ Intel GPU on the Mac, and fullscreen video has blue artifacts. What should I do?
    This is a video driver bug and not something we can fix directly. For Chrome, one of our amazing users has made an extension that fixes the issue: VideoFixer for f.lux
  • I have a newer 2017+ Macbook Pro running High Sierra (10.13), and sometimes white colors turn cyan.
    This fix from Apple is only in Mojave, so you'll want to upgrade to 10.14.
  • On El Capitan, sometimes my screen is tinted during the day, even after quitting f.lux. How do I fix this?
    This is no longer happening for most people as of the 37.7 update. In most other cases, the fix is to disable automatic brightness AND reboot. Look at System Preferences > Displays > Color.
  • How do I turn off the "waking up" notifications?
    If they are happening at the wrong time, make sure your wake time is set to the right number in "Preferences". If that's no good either, use the Options menu to turn off "Backwards Alarm Clock".
  • f.lux on 10.12.4 with Darkroom mode has really bad-looking text
    To fix, look in System Preferences > General and uncheck "Use LCD font smoothing when available"
  • With f.lux on Mac OS El Capitan (10.11), the display is flickering rapidly when the light changes
    This is fixed in the later versions of El Capitan. In older ones, El Capitan has a new automatic brightness feature that conflicts with f.lux on some models. You will need to disable "Automatically adjust brightness" in System Preferences, Displays. Some people may have to reboot after this.

F.lux at work

  • Can I use the free version of f.lux on my work computer?
    Yes, with the knowledge and permission of your employer. Our EULA allows users to download and use the software on work machines. Our license is with you, the end user, and not with the company. If you have rights to install it yourself, and your employer approves, we allow it under our personal license.

  • For any "site license" situation (centrally managing installs for many machines)
  • When an IT department wishes to have control of automatic updates and default settings
  • Whenever a company recommends f.lux to employees (corporate wellness)
  • If a company has regulatory requirements (like banks do)

In these cases, you should obtain a corporate license here. Currently this build is only available for Windows, and it is covered by a separate Corporate EULA.

F.lux on Windows

  • How do I find or change settings?
    Settings are located in a menu to the left of your system clock. In Windows, this is at the bottom right corner of your screen. On a Mac, it's at the upper right. NOTE: f.lux does not appear in your dock, settings, or your alt-tab menu. Currently settings are only acessible through the taskbar.
  • Where is "Safe Mode" in f.lux v4?
    We built it in! The new build has massively less impact on games and the overall system. If you are a gamer and want less impact while playing games, you can also try Options -> Very Fast transitions.
  • The Windows f.lux UI now shows everytime I reboot. How do I make it hide again?
    We made f.lux do this when you haven't set your location yet. Our automatic setting is pretty bad (especially if you don't live in the USA.) Click on the location button and set things up, and f.lux will auto-hide again.
  • How do I use the new warmer colors and "Darkroom" mode on Windows?
    These features require a small change to your system and a reboot. You can look in the "Lighting at Night" menu and choose "Expand Color Range". f.lux will ask for Administrator access and offer to reboot your PC Now or Later. After your next reboot, you will be able to access more dramatic color changes.
  • The colors on Windows changed since the f.lux update. How do I go back?
    f.lux v3 started reading your system profile and installing it. If you don't like your profile, you can change it in from the Windows Control Panel -> Color Management. We recommend finding a profile that displays accurate colors (or one you like).
    f.lux v4 also tries to read properties of your monitor. If you want to try turning that off, look for "Use display data for better color accuracy" in the Options menu.
  • My cursor is bright white on Windows. How do I fix it?
    This happens when your videocard displays uses a "hardware cursor". In f.lux v4, you can look in the "Options" menu and turn on "Software mouse cursor when needed". In the older version, enabling Mouse Trails can help: See this post on StackExchange for more info.
  • How do I dim my desktop monitor?
    In Windows f.lux, use the hotkeys Alt-PgDn and Alt-PgUp. (But if you're on a laptop, you should mostly dim your backlight to keep contrast.)
  • How do I disable the Windows f.lux hotkeys?
    Find the Options menu, and turn them off there.
  • I changed my system profile on Windows and f.lux is using the old one
    Yes you should restart f.lux, or wait 10 minutes for us to read it again.
  • On Windows XP, the f.lux location dialog does not work. What should I do?
    Due to the "Poodle" bug in SSLv3, our server does not allow connections from IE on Windows XP. If you use Chrome or another browser, you can use this map page and paste your location into f.lux instead.

General questions

  • f.lux is not showing my location very accurately. How do I fix this?
    This is by design, and it's to help protect your privacy. We round your location to 0.1 degree. This lets f.lux estimate your sunset timing within about 30 seconds, which is all we need.
  • f.lux is transitioning a few hours early (or late) and I've set my location properly. What do I do?
    Check if your clock is correct using our tool here (it should be within 10 seconds usually). This problem usually means your timezone is set to the wrong one. Double-check by clicking on your system clock. When this happens, usually the local time is set so it looks right, but because it's in the wrong timezone, your computer reports that it's several hours ahead or behind where it actually is.
  • I installed this but it looks too pink/orange.
    On first use, it can take a while to adjust to the halogen settings. Try adjusting the color temperature sliders under Settings until you find one you like. Start with fluorescent or halogen and change it when your eyes adjust. When you disable f.lux, your screen will return to your normal calibration. We're used to looking at very blue computer screens, so it can seem unnatural at first. Most LCD displays are calibrated to display at 6500K, which has even more blue than noon sunlight (5500K).
  • One of my monitors is flickering - it shows white and then orange quite frequently. What should I do?
    (This answer is PC and Mac when used with non-Apple monitors) Look in the On-Screen Display (OSD) and see if you can turn off DDC/CI (the monitor configuration protocol). Some older monitors did not handle color changes well and would reset to white before accepting new settings. This is fine if you change settings once a month, but not so good if you do it more often like f.lux does.
  • When I scroll text with f.lux on, I see a brief red afterimage. Why?
    LCDs are faster at doing "gray to gray" color changes than "black to white", and if you imagine how f.lux is changing your blue channel, the transitions that used to be black-to-white are now black-to-gray.
    But what's making this worse these days is a number of GPUs and displays are using a technology called Response-Time-Compensation or "Overdrive" to improve the speed of these gray transitions even more (without improving the speed for black to white much at all). Now, the red channel is noticeably "slower" than the blue (because f.lux has made the blue channel faster). So as you scroll black text, you might see some red afterimages on these displays or GPUs.
    Our recommendation: turn off overdrive (or reduce the amount of it) using your driver or on-screen-display.
  • What is the right color setting for me?
    You're at the right color when your monitor screen color looks like the pages of a book under your room lights. We're all used to monitors giving off a 6500K glow, which is even bluer than sunlight. If the default settings of f.lux feel too extreme to you, try setting it to fluorescent, and once your eyes adjust, set it to a warmer temperature. Some studies indicate blue light is beneficial during the day, but late at night it can negatively affect your sleep pattern. Our unofficial study indicates that f.lux makes your computer look nicer in a dark room.
  • This changes too fast, it always shocks me.
    The f.lux transition can be CPU intensive, so f.lux tries to be polite about it. To make it slow, you can use the special 1-hour slow transition option under settings instead.
  • I work nights. How should I use f.lux?
    Our best advice is to set your wake time a few hours early.
  • How long is Movie Mode and what does it do?
    It's 2½ hours. We designed Movie Mode to preserve sky colors and shadow detail, while still providing a warmer color tone. It's not perfect on either count, but it strikes a balance.
  • What are the presets in Kelvin?
    Ember: 1200K
    Candle: 1900K
    Warm Incandescent: 2300K
    Incandescent: 2700K
    Halogen: 3400K
    Fluorescent: 4200K
    Sunlight: 5500K
  • How do I download the old version?
    Try flux-setup3.exe. We do not recommend using v3, as it has signficantly more performance impact on the system. Most people can find find advice here that will make v4 better for their needs.

Troubleshooting: Flickering and Tinted screens

  • f.lux doesn't work on Windows 10. Help?
    Immediately after upgrading to Windows 10, many machines are using a basic video driver that does not work with f.lux. Windows Update will usually get a better driver (within a day) to a version that works with f.lux. In some cases this does work on its own, so we recommend that you update your drivers with the manufacturer's latest version.
  • I installed f.lux but I can't see any change.
    Is it past your local sunset time? Just wait, and f.lux will kick in at sunset.
    Is your location set correctly under Settings?
    Check that your night-time settings are not set to Daylight.
  • I uninstalled f.lux and my computer is still orange, what gives?
    Some users have encountered a problem where f.lux is no longer running but the screen still appears tinted. If you have checked the Processes tab in Task Manager and there is no f.lux process present, this means another program has absorbed the f.lux color profile. The workaround to restore your screen to its normal profile is as follows: Reinstall f.lux. In the Settings Menu, set both the Night and Daytime sliders to daylight. After 24 hours, any other programs should have re-absorbed the new profile, and you may uninstall f.lux with no more changed colors.
  • My Lenovo laptop is still tinted after uninstalling f.lux.
    Disable the "Lenovo Vantage Eye Care Mode".
  • My AMD Vega does not change colors at all.
    Try to upgrade to a driver version 19.9.1 or later.
  • My Windows 10 computer flickers at sunset.
    Disable Windows Night Light.
  • F.lux has problems after a Windows Update.
    Most problems like this can be fixed by updating your video drivers.
    Try one of these links: NVIDIA drivers, AMD Radeon drivers, Intel drivers.
  • My NVIDIA GPU just stopped working with f.lux. What to do? (2020-2021 drivers)

Please disable "override to reference mode" in the NVIDIA Control Panel. This option appears to be turning on by itself for some people.

  1. Run Device Manager and navigate to Display Adapters : Intel HD Graphics Family. Pick the "Driver" Tab.
  2. Check which version you have. If it's less than, you'll want to update (the early-2014 drivers that end with "3412" up to "3621" can cause slowdowns and crashes with f.lux).
  3. Download a new intel driver here: Intel HD drivers
    If using a "standard" Intel video card, just get the EXE and install it. You're done! If using a Surface Pro 3 or "customized" OEM driver, pick the ZIP download so we can force the install.
  4. If you picked the ZIP, unzip it and then:
    1. Back in Device Manager, click "Update Driver" and "Browse my computer. "
    2. Choose the Downloads folder and the zip folder you just extracted.
    3. If Windows refuses this new driver, you should Uninstall and Delete the existing driver and start again from step #1. Windows will use its basic driver in the interim (you won't be without video.)

    The Catalyst Control Center is an optional component that can be uninstalled, and you might consider doing this if you're not frequently adjusting your settings for gaming or other reasons. Use Add/Remove Programs, and choose "AMD Catalyst Install Manager" to proceed.
    Do not uninstall the Install Manager, but instead use it to uninstall Catalyst Control Center. In our test, this didn't even require a reboot. Also, leave a note on this page (with the driver version) so we can report it to AMD.

    Several people have reported that QuickGamma works well and produces good profiles that f.lux can read.

    If you use a Spyder, the software profile loader may cause f.lux to flash periodically. You can disable the Spyder software on startup, and use f.lux instead to load the profile. Also, when you're calibrating a display, you'll want to do the opposite and quit f.lux before you do.

    F.lux v3 for Windows (2013 version)

    • What does Safe Mode do on Windows?
      Safe Mode does two things: 1. It disables our layered window for compatibility with some older machines. 2. It disables all polling we normally do to ensure that we're the active color profile. Logging in, changing video resolutions, and Administrator (UAC) prompts can all reset f.lux's color changes. With Safe Mode, we do not fix these automatically, in order to minimize the impact we have on the system. If an app resets the colors, you can click on the f.lux icon to have us restore our profile. Transitions (sunrise, sunset) still happen as usual. Use Safe Mode if you think f.lux slows down your computer.
    • I work nights. How do I flip the day and night settings?
      PC f.lux users can unlock the color temperature sliders by holding down the control key while setting your temperature, so night can be swapped with day. We're working on a feature that lets you control time settings more closely.
    • Since upgrading to Windows 10 Anniversary, my non-DisplayLink screen is flashing a lot, but only when I have my USB monitor or docking station plugged in Yes, we had a bug that caused this and the main build has been updated (v3.12). Please get an updated build here.

    More questions

    • Plenty of things already change the brightness of my screen. Why is this different?
      f.lux changes the color temperature of your display. Natural light is more blue, while most artificial light (including candlelight) is warmer. Incandescent bulbs, which we're all used to, become more red in tone when you dim them. But newer LEDs and CFLs don't - this includes the backlight on your monitor. If you're a photographer, you've probably dealt with this, since pictures taken inside at night are always much more brown than photos outside.
    • Isn't this exactly the same as the Macbook ambient light sensor?
      No, though they do work together nicely. The ambient light sensor measures the brightness of the light in your room and adjusts the brightness of your screen based on that. f.lux changes the color of your screen and warms it up according to the type of light you're using and the time of day. f.lux doesn't use ambient brightness to adjust colors. You might be in a dark room with very cool light, you wouldn't really want your monitor to look warm, but you would want your display to look dimmer. We've found that when your screen colors match the color of your ambient light correctly, you don't need to adjust monitor brightness as much.
    • What is color temperature, exactly?
      The term color temperature is a way to numerically describe how much red or blue light is illuminating a room. Color temperature is measured in Kelvins, and is determined by the kind of light you're using. Confusingly, warmer (more red) light sources are described in lower degrees Kelvin. Compared to indoor lighting, daylight is cool - very blue. A candle is around 1800K, while a sunny day might be 6000K. An overcast day is more blue, so it might be around 7000K. Most computer monitors display around 6500K. If you are using incandescent task lights behind your computer, those are around 3000K.
    • I'm a designer / photographer / artist so I can't use f.lux. This isn't for me!
      f.lux was created by people who care a lot about accuracy in colors. We know you want to make sure your colors are perfect so there is an option to disable f.lux for 1 hour at a time (for example, while using Photoshop). This setting returns your screen to its normal settings. In the future we plan to allow automatic disabling of f.lux when you launch certain programs. f.lux is not designed for use during advanced color work, but it's fine for layout or HTML.

    Installing & Uninstalling

    1. Click the f.lux Windows download link.
    2. Run the installer and the f.lux settings page will appear.
    3. Enter your location and select the type of lighting in your room at night.

    1. If you find flux.exe running and do not want it:
    2. Go to the Start Menu > Add/Remove Programs > Uninstall f.lux

    1. Go to the f.lux Settings panel (to the left of your system clock)
    2. Choose "Quit f.lux"
    3. In Finder, select and delete the f.lux app, and empty the trash.

    If you still have a tinted screen, keep going with these instructions until things improve:

    How to Use Flux in Soldering-Step by Step Guide

    In electronics, it is crucial to use flux when soldering in order to make solid and shiny joints. The soldering iron tip must be properly cleaned and the iron must be placed on a stand before starting the activity.

    To tin, the tip with solder, apply solder to the tip of the iron when it is hot. Cleaning the tip with a sponge is needed after tinning. The tinning process protects the tip from oxidation, reduces wear, and enhances heat transfer.

    Step 1- When soldering two pieces, it is good to use steel wool or scotch brite to remove oxide layers from the surface.

    Step 2- Using a brush, apply flux with solder to both pieces of the terminal that need to be connected.

    Step 3- To heat the joint without burning away the flux, use adjustable temperature control to set the iron to the right temperature (400°C/752°F). Inhaling fumes or direct skin contact with a flush is dangerous, so always take precautions.


    Most traditional apps use centralized two-factor authentication (2FA) , which can leave accounts vulnerable to attacks, such as SIM swapping and data breaches.

    ZelCore uses the power of blockchain to offer a Decentralized two-factor authentication. Secure your ZelCore account with d2FA, which stores and verifies your encrypted PIN on the blockchain.

    A protocol that is truly seamless, secure, and private.

    After the soldering process is over, it is important to clean the board to remove any unwanted flux residue that can affect the performance of the board and can even cause electrical short circuit. No-clean flux doesn’t need any cleaning. In case of fluxes that need cleaning after soldering, solvent cleaning or aqueous cleaners can be used. Most soldering flux manufacturers and vendors also supply flux cleaners.

    “Several factors determine the type of solder flux to be used during soldering”

    But you don’t say which flux is best for each scenario.

    Yes, You are correct. The type of solder flux needed in soldering depends on the type of soldering you are doing.
