Coherence Light Display
Turn any light fixture into a heart coherence display
Light up the world. And now light up your room.
See your coherence transformed into visible light, and spice up our experience of global connectivity. As you get into coherence, using the Global Coherence App, the light glows and changes color depending on your coherence level.
The LIFX 800-Lumen LED Wi-Fi lightbulb changes as your coherence changes. Works with individual or group coherence levels.
It’s Easy!

Get Started Guide
Step 1.
Purchase the LIFX 800-Lumen LED Wi -Fi lightbulb (or other supported LIFX bulbs listed below)
No hub required. You can order it from Amazon, Best Buy or wherever LIFX products are sold. The LIFX bulb screws in like any traditional lightbulb.
Supported LIFX lightbulbs:
- LIFX Color 800-Lumen
- LIFX Color A19 1100 Lumens
- LIFX Color BR30 1100 Lumens
Step 2.

Step 3.
Open the Global Coherence App. Go to: Settings > Lightbulb.
Tap Available Lightbulbs.
Then choose one or more lightbulbs from the list.
*Works only with Wi-Fi color bulbs made by LIFX.
Step 4.
Experiment with the optional settings, start a session and see the light.
Use the slider to set the brightness.
Pick a coherence source, you or the group.
The coherence score of the selected source will control the color of the lightbulb.
Set the coherence score color range.
Adjusting the slider maps the color range of the light to coherence scores. The high set point is the score at which the light reaches the final color in the range.
There are 4 colors in the range: red, blue, green and magenta.
For example, if the slide control is set to 5 the bulb will change to magenta when the coherence score is 5 or above.
FAQs
What is the HeartMath Coherence Light Display?
The Coherence Light Display is a feature of the free HeartMath Global Coherence App that turns a supported LIFX Wi-Fi color bulb into a visual display of heart coherence. During a session, the bulb changes color as your personal or group coherence score changes. HeartMath provides the app software; the bulbs are made and supported by LIFX.
Which LIFX bulbs work with the Coherence Light Display?
The Coherence Light Display works with three LIFX Wi-Fi color bulbs: LIFX Color 800-Lumen, LIFX Color A19 1100 Lumens and LIFX Color BR30 1100 Lumens. It works only with Wi-Fi color bulbs made by LIFX, and no hub is required. The bulbs are sold by retailers such as Amazon and Best Buy. Compatibility confirmed as of September 1, 2026
How do I set up the Coherence Light Display?
Set up the Coherence Light Display in four steps: 1) buy a supported LIFX Wi-Fi color bulb and screw it in; 2) install the LIFX app and connect the bulb to your home Wi-Fi; 3) in the Global Coherence App, go to Settings > Lightbulb > Available Lightbulbs and select your bulb; 4) set brightness, coherence source and color range, then start a session.
How does the light respond to my coherence score?
The bulb’s color follows the coherence score of the source you choose, either you or your group. It moves through four colors, red, blue, green and magenta, as coherence rises. A slider sets the high set point, the score at which the bulb reaches magenta; for example, at a setting of 5 the bulb turns magenta when the score is 5 or above.
Can I use more than one LIFX bulb with the Coherence Light Display?
Yes. You can use multiple LIFX bulbs with the Coherence Light Display at the same time, including bulbs in separate rooms, as long as all bulbs are on the same Wi-Fi network. Select each bulb under Settings > Lightbulb > Available Lightbulbs in the Global Coherence App.
Why isn’t my LIFX bulb showing up in the Global Coherence App?
The Coherence Light Display requires Wi-Fi, so first confirm the bulb is a supported LIFX color model, is set up in the LIFX app and is on the same Wi-Fi network as your phone. Then reopen Settings > Lightbulb > Available Lightbulbs. For bulb hardware or Wi-Fi pairing problems, use LIFX support. When a session ends, the bulb returns to its previous state. Works with your camera being used a sensor or the other heartmath coherence sensors.
