The Right Light at the Right Time

Light from our TV screens has been shown by doctors and professionals to ruin the quality of our sleep, affecting our health, productivity, and mood. The driftTV allows you to enjoy that relaxing TV show before bed and still get a good night's sleep!

  • With our custom algorithm, you can enjoy TV without the harmful side effects
  • Automatically adjust the light emissions of your TV over time with a seamless transition period
  • A simple and easy to use interface allows the driftTV to work according to your schedule
In-depth Harvard study on light from TVs

Smooth Transitions Over Time

The driftTV removes the harmful side effects of TV light from the content you watch on your TV. That way you can enjoy your movies and shows without having your sleep affected.

Our custom algorithm works for you. The driftTV gives you the option to set exactly how much it will work for you. For example, you can set your driftTV to 3500K and your TV will mimic that color temperature. It will transition from your normal daytime setting to the nighttime driftTV setting over a period of one hour. That way, the transition is seamless and virtually unnoticeable.

Smooth Transition

This transition will take place one hour before you wish to go to bed. So when your bedtime comes around, you will not lie awake at night yearning for the sweet embrace of the dream world. The driftTV will maintain its settings while you sleep. If you wake up in the middle of the night and turn on your TV, your sleep schedule will not be harmed by extra light. When it does come time to awake and arise, the driftTV will automatically begin to transition back to your normal daytime settings one hour before you get up.

Override When you Need it

Friends coming over? Planning a late night gaming session? Want to temporarily try out a different setting? The driftTV has an override feature that will allow you to temporarily bypass your normal schedule. Simply switch the driftTV to override mode and select the settings you want. The driftTV will then remain at that setting until you switch it back to auto mode.

How to Use driftTV With Multiple Sources and Displays

Since the driftTV has one HDMI input, you will need an HDMI switch or AV receiver if you wish to have the driftTV work with all of your video sources. If you rely on your TV’s built-in switch to select your various HDMI sources, you’ll probably need an HDMI switch.

We’ve tested our HDMI switches specifically with driftTV: Check out our bundle and save

Not Sure If You Need an HDMI Switch?

First things first let’s talk about what exactly an HDMI switch does. HDMI switches are the traffic lights at the intersection of all your HDMI device inputs. The HDMI switch allows all signals to be present and active, but only allows one to pass through to the TV at a time.

For this reason, HDMI switches are useful for people that have multiple HDMI video source devices (examples of common HDMI sources: Blu-ray players, DVRs, Streaming boxes, etc.) and want to switch between them one at a time on their TV.

This switch capability is great when you are using a product like the driftTV which processes a signal before sending it to the TV. Without the HDMI switch you would have to manually plug in the driftTV to a different input every time you wanted to change sources, or you would need a driftTV for every device you have plugged into your TV. With an HDMI switch you can send all the signals through a single driftTV with ease.

How to Update the Firmware

Note: All new driftTV purchases have this update pre-installed so you do not have to do it yourself.


This will not void your warranty, if you require further instructions please contact our support staff and we will assist you
  1. Download the update file onto a USB flash drive (ensure that nothing else is on the USB flash drive)
  2. Unplug all cables from your driftTV
  3. Peel off the adhesive feet and unscrew the the screws from the casing
  4. Remove the top portion of the case very carefully. It is ok if the button caps fall off, they will be put back on later
  5. Reattach the cables to your driftTV
  6. Plug the flash drive into the USB slot located on the circuit board. Be careful to not move the flash drive or USB port around too much, as it is fragile
  7. Hold the select button (located on the far right) for five seconds. Once you release the button, the indicator light will flash and the unit will start the update process. Do not remove any cables or push any other buttons during this phase
  8. Once the picture returns to the screen, the update process is complete
  9. Unplug the cables from the unit
  10. Place the button caps into the appropraite spot on the top portion and place the top portion on the bottom half until it snaps into place
  11. Screw the screws back in and reattach the adhesive feet
  12. Reattach your cables and enjoy your new and improved driftTV!

Cons: The entire reason I bought this item was to modulate the light from my PS4 Pro and the damn thing wont hook up. At this point its cheaper the resell it than to return it after shipping and customs

Happy with the purchase, needs CEC support

Pros: It works. Blue levels in the image are reduced on schedule. Seems well built, will probably last longer than the devices it's connected to.

Cons: - It interferes with CEC on the Apple TV - It prevents the Apple TV from determining what TV model you have for IR volume control - The color shift is fast, unlike f.lux it seems to happen very quickly right at the time you have configured to go to sleep - Configuring using the buttons on the device can be annoying. If you have a Logitech Harmony I strongly suggest configuring that first.

Other: Despite all of the cons, I'm still happy I purchased it. The basic functionality works perfectly, and I'd buy it again.

Pros: Sounds like a great device.

Cons: Won't work with 4K TV.

Other: Sewell needs to make it easier for customers to understand that problem. That said I'll be waiting for Drift that does.

Great Solution!

Mars Colony or Bust! - 1/18/2017 7:57:49 PM

Works as advertised. Removes blue signal from the red-green-blue signal according to desired intensity. Life saver for sleep hygiene. Would definitely purchase again, and would recommend to others.
