Frequently Asked Questions
Will the cool white 6500K setting actually help me focus during work?
Yes, cooler color temperatures in the 5000K to 6500K range mimic daylight and have been shown to support alertness and reading speed. Set your home office bulbs to 6500K in the morning and you get the same energizing effect as a sunny window without harsh blue overhead lighting.
Can I schedule a focus block where the light shifts to bright cool and back to warm?
Yes, the timer and schedule features in the Daybetter app let you automate color temperature changes throughout the day. A typical setup is 6500K cool white from 9am to 12pm, neutral white during lunch, and 3000K warm white after 5pm to wind down.
Are 800 lumens bright enough for a home office or study desk?
For a single desk lamp, 800 lumens is plenty for reading and screen work, and for a full room office you would want two or three bulbs. The 4 pack is ideal because you can put one in the overhead fixture, one in a desk lamp, and one in a floor lamp.
Will the music sync feature distract me during deep work?
The music sync only activates when you tap into the scene, so it does not interrupt normal white lighting routines. You can leave it off during focus hours and turn it on during breaks or end of day decompression.
Can I use these for video calls so I look better on camera?
Yes, set the bulb to a neutral 4000K to 5000K and you get even, daylight balanced light on your face without the orange cast of typical lamps. The high CRI 90 rating also means colors look accurate on camera, which is helpful for presentations.
How does this compare to a dedicated desk lamp for productivity?
A dedicated desk lamp is more directional and adjustable, but a smart ceiling or floor lamp bulb covers the whole room for a less harsh environment. Many people use both, with the smart bulb on the ceiling for ambient focus lighting and a desk lamp for task lighting.
Is this better than a traditional LED bulb for a study setup?
Yes, because you can adjust the color temperature throughout the day rather than being stuck with one tone. Cool tones in the morning and warm tones at night support your circadian rhythm better than a fixed color bulb.
Can I link multiple bulbs in my office to one command so I do not break my flow?
Yes, the group control feature lets you bundle every bulb in your office into a single named group. Say 'Alexa, office on' or tap a scene and the whole room responds at once so you can stay in deep work mode.
I am worried the WiFi setup will be too complex for my office routine.
Setup is roughly two minutes per bulb. Screw it in, open the Daybetter app on a 2.4GHz WiFi network, and the app walks you through pairing. After that it reconnects automatically and you control it through voice or the app, no extra hub to install.
Will the timer run if my WiFi goes out during the workday?
Schedules run from the cloud, so a brief WiFi outage will pause them until the connection returns. Once WiFi is back, scheduled routines resume at the next cycle without needing to be re programmed.
Is 9 watts really enough to replace a 60 watt bulb for a productive workspace?
Yes, LED efficiency means a 9W bulb produces the same usable light as a 60W incandescent, around 800 lumens. The perceived brightness is even higher because the light is directional and high CRI, so the room reads brighter than the wattage suggests.
How do I set up the TJOY smart bulb for the first time?
Screw the bulb into any standard E26 socket and turn on the wall switch. Download the Daybetter app, create an account, make sure your phone is connected to a 2.4GHz WiFi network, and tap the plus icon to add a device. The app will detect the bulb over Bluetooth, prompt you to enter your WiFi password, and finish pairing in about 60 to 90 seconds per bulb.
How do I connect the bulb to Alexa or Google Assistant after setup?
In the Daybetter app, open Settings for the bulb, choose 'Voice Services,' and link your Alexa or Google account. Then say 'Alexa, discover devices' or 'Hey Google, sync my devices.' The bulb will appear in your smart home app and you can rename it by room, for example 'Bedroom Lamp' or 'Office Ceiling.'
How do I reset the bulb if it stops responding or I change WiFi networks?
Turn the wall switch on and off five times in a row with about one second between each toggle. The bulb will start flashing quickly, which means it is in pairing mode. Open the Daybetter app and re add the bulb to your new 2.4GHz network.
Does this bulb work with Apple HomeKit or SmartThings?
The bulb is designed to work with the Daybetter app, Alexa, and Google Assistant. It does not currently support Apple HomeKit or Samsung SmartThings directly. You can still control it through Alexa or Google, which work alongside most Apple devices via voice.
Will it work with my 5GHz WiFi router?
Smart bulbs need a 2.4GHz WiFi signal, which almost every modern router broadcasts alongside 5GHz. If your phone connects to 5GHz by default, switch to the 2.4GHz band during setup and then return your phone to its normal network.
What is in the box when I order the 4 pack?
You receive four TJOY A19 E26 smart LED bulbs in retail packaging, a quick start guide, and access to the Daybetter app. You will need to supply your own lamp, fixture, or lamp socket. A 2.4GHz WiFi network and a smartphone running iOS 9 or Android 5 or later are required.
Is it safe to leave these bulbs on for long periods?
Yes, the bulbs are FCC and UL certified, rated for 25,000 hours of use, and generate very little heat compared to incandescent bulbs. They are designed for daily extended use in living areas, bedrooms, and home offices, and the 1 year warranty covers any manufacturing defects.
What happens if the WiFi goes out? Can I still turn the light on?
Yes, the bulb still functions as a standard light when WiFi is unavailable. Use the wall switch to turn it on and off, and the bulb will remember the last color and brightness setting. Once WiFi returns, scheduled routines and voice control resume automatically.
What is the difference between a smart bulb and a regular LED bulb?
A regular LED bulb is on or off at one fixed color temperature. A smart bulb connects to WiFi and gives you app control, voice control, dimming, color changes, scheduling, music sync, and group control, all without needing a separate hub in this case.
