Method 1: How to Change Light Mode on a Fantech Keyboard Using Fn Hotkeys
The fastest and most common way to modify backlighting effects is through the physical Function key located on your keyboard layout. Fantech designs their board firmware so you can switch preset patterns, adjust overall brightness, and alter effect directions in seconds without minimizing your game or closing active applications.
Locate the Fn key on your bottom key row, usually situated to the right of the spacebar or near the right Alt and Control keys. You will combine the Fn key with specific keys along the top row, navigation cluster, or arrow keys to trigger lighting commands.
Step 1: Locating the Lighting Hotkey Row
On most Fantech mechanical keyboards, the lighting control keys feature small printed sub icons on the front or top of the keycaps. Common preset toggles reside on keys F1 through F12, or on the dedicated cluster containing Insert, Home, Page Up, Delete, End, and Page Down.
Step 2: Pressing the Primary Preset Switch Combo
To cycle through built in lighting modes such as static color, breathing wave, reactive ripple, spectrum cycle, or rainbow runner, hold down the Fn key and press one of the following secondary keys depending on your exact Fantech model:
- Fn + Insert: Cycles through primary animation modes such as wave, spiral, and rainbow drift.
- Fn + Home: Switches between solid breathing colors and reactive backlight modes that light up keys only when struck.
- Fn + Page Up: Toggles custom zone lighting where only movement keys like WASD and arrow keys remain illuminated.
- Fn + Delete: Changes color palettes within the current active lighting mode.
- Fn + End: Stops active animations and locks the backlighting into a solid static hue.
- Fn + Page Down: Toggles side strip ambient lighting on models equipped with outer rim LEDs.
Simply press your chosen combination repeatedly until you arrive at the exact illumination style you prefer. Each press moves the internal controller to the next preset in line.
Step 3: Fine Tuning Brightness and Speed
Once you select a light mode you enjoy, you can adjust its intensity and animation velocity so it remains comfortable for your eyes:
- Fn + Up Arrow: Increases key backlight brightness level.
- Fn + Down Arrow: Decreases key backlight brightness level until backlighting turns off completely.
- Fn + Right Arrow: Speeds up dynamic lighting animations like rainbow waves or pulse cycles.
- Fn + Left Arrow: Slows down dynamic lighting animations for a calmer, less distracting effect.
Method 2: Changing Light Modes Using Fantech Software
For users who want complete creative freedom over their illumination, downloading the official Fantech companion software unlocks advanced customization that onboard key combinations cannot match.
Fantech provides lightweight configuration software for their most popular keyboard models, enabling per key RGB lighting, custom color palettes, synchronization options, and persistent user profiles.
Follow these steps to customize your light mode through the desktop software interface:
Step 1: Download the Correct Software Driver
Visit the official Fantech support portal and search for your specific model number, which is printed on the sticker underneath your keyboard chassis.
Download the correct driver executable file for your Windows operating system version. Installing software intended for a different model may prevent the lighting commands from reaching your keyboard board controller.
Step 2: Install and Launch the Application
Run the installer, complete the quick setup wizard, and launch the Fantech driver application. Ensure your Fantech keyboard remains plugged directly into a primary USB port on your desktop or laptop during this process rather than an unpowered USB hub.
Inside the user interface, select the main tab labeled Lighting, LED Effects, or Light Settings. You will see a graphical preview of your keyboard alongside a drop down menu listing available preset lighting modes.
Step 4: Select and Customize Your Preset
Choose your preferred mode from the drop down menu. Software control gives you granular sliders for parameters that hotkeys cannot reach:
- RGB Palette Pickers: Choose any precise custom shade using hex codes or color wheels rather than relying on preset primary colors.
- Animation Speed Sliders: Fine tune movement speed with high precision.
- Direction Controls: Set rainbow waves and light ripples to travel left to right, right to left, top to bottom, or outward from the center.
- Per Key Lighting Paint Tool: Select individual keys on the screen and assign unique colors to each one. This allows you to create custom layouts for specific video games, highlighting hotkeys, inventory slots, and movement controls in distinct colors.
Step 5: Save to Onboard Profile Memory
Once your custom lighting setup looks perfect, click Apply or Save Profile. Most modern Fantech keyboards feature onboard flash memory, meaning your lighting preferences save directly to the peripheral itself.
Once saved, your custom light mode will remain active even if you unplug the keyboard and plug it into a different computer that does not have the Fantech software installed.

Preset Light Modes Explained
Fantech keyboards come programmed with diverse lighting modes designed for varying environments, mood preferences, and usage scenarios. Understanding what each mode does helps you select the best setting for work, gaming, or content creation.
Spectrum Wave Mode
This dynamic mode sends a continuous stream of vibrant rainbow colors rolling across the keycaps from side to side. It showcases the full color capability of your keyboard and serves as an eye catching centerpiece for gaming desks.
While visually striking, some users prefer calmer modes during long reading or writing sessions.
Static Solid Color Mode
Static mode locks all key backlights into a single unchanging color of your choice, such as deep blue, warm red, clean white, or emerald green. This mode delivers zero visual distraction, making it the top choice for professional work, coding, and late night study sessions.
Breathing Pulse Mode
In breathing mode, the keys gently illuminate to full brightness before fading down to black in a smooth, rhythmic cycle. You can lock breathing mode to a single color or set it to transition through a series of different hues with each pulse breath.
Reactive Ripple Mode
Reactive modes keep the keyboard backlighting completely dark or dim until you press a key. Upon pressing a keycap, a burst of light radiates outward from that single key across the board like ripples on water. This mode provides instant visual feedback that mechanical typing enthusiasts love.
Custom Game Zone Mode
Game zone lighting isolates key backlight activation to specific functional zones while keeping non essential keys unlit. Popular built in presets highlight the WASD keys, arrow keys, number keys, or common hotkeys used in competitive titles.
Using game zone lighting reduces visual clutter and helps your fingers locate critical keys during intense fast paced matches.
How to Turn Off or Reset Fantech Keyboard Lighting
There are times when you may want to disable all keyboard lighting entirely, such as when watching movies in a dark room, leaving your computer on overnight, or working on limited battery power with a laptop.

Frequently Asked Questions
Why does my Fantech keyboard change light mode on its own when I restart my PC?
If your keyboard resets its light mode after a computer reboot, it usually means your chosen lighting effect was set via software without being saved to the board onboard memory, or the companion software is not configured to launch automatically with Windows startup.
Open your Fantech software settings, ensure Start with Windows is enabled, and click Save Profile to flash your settings directly to the keyboard hardware.
Can I customize light modes on Mac operating systems?
Yes, hardware hotkey combinations using the Fn key work identically across Windows, macOS, and Linux systems because firmware controls those commands directly on the board. However, official Fantech configuration software is primarily designed for Windows.
Mac users can set custom color profiles using a Windows PC first, save the profile to the keyboard onboard memory, and then plug the keyboard back into their Mac where those lighting preferences will persist.
Does keeping backlighting turned on reduce the lifespan of my keyboard?
Modern Fantech keyboards use high efficiency LED diodes rated for tens of thousands of continuous operational hours. Keeping backlighting on continuously will not harm your hardware.
However, running LEDs at maximum brightness 24 hours a day generates mild internal warmth and can slowly cause slight LED color decay over many years. Setting LEDs to turn off after system sleep or running them at 50 to 70 percent brightness preserves diode lifespan indefinitely.
What is the difference between Rainbow LED and True RGB lighting on Fantech keyboards?
Rainbow LED keyboards use fixed color backlights behind specific rows or zones. While you can change animation patterns, wave speeds, and pulse effects, individual keys cannot change their physical color hue.
True RGB keyboards feature full spectrum color diodes under every single keycap, allowing you to select from 16.8 million distinct colors for any key through software settings.
Can I sync my Fantech keyboard lights with my computer motherboard software?
Selected high end Fantech keyboards support universal RGB synchronization standards. If your specific model supports third party integration, you can connect it with popular software suites such as SignalRGB or OpenRGB to match your keyboard backlighting with your desktop fan LEDs, RAM modules, and mouse illumination.
