The prices of smart light bulbs have been coming down steadily, with many good white-only options in the $10 range. The Treatlife Smart Wi-Fi Color Bulb is available on its own for $12.99, or under $10 when purchased in a pack of two or four, making it the most affordable color bulb we’ve tested—not to mention more affordable than many of the white-only bulbs out there. It provides rich colors and adjustable whites, as well as support for Amazon Alexa and Google Assistant voice commands. It lacks support for IFTTT applets that allow it to be triggered by third-party smart home devices such as cameras and motion sensors, and it doesn’t support Apple’s HomeKit home automation platform, but you'll have to spend around twice as much for a bulb that does.

Treatlife Bulb Features and App

The Treatlife bulb is available on its own for $12.99, in a pack of two for $19.99 ($10 each), or in a pack of four for $35.99 ($9 each). It's an A19 shaped LED with an E26 base that will fit most standard lighting fixtures. It measures 2.3 inches in diameter, is 4.5 inches long, and puts out 810 lumens, which is roughly equivalent to 60 watts. The bulb is dimmable and can produce 16 million colors, and it has a wide tunable white temperature range of 1,200K to 9,600K. It also has a built-in Wi-Fi radio, which means it doesn’t require a hub.

You can control the bulb with the same Smart Life mobile app (for Android and iOS) used to control other Treatlife devices, such as its Smart Plug. You can also control it using Alexa and Google voice commands, but it doesn’t support Apple’s HomeKit platform or work with IFTTT applets that allow it to interact with third-party smart devices. It also lacks the power usage reports that you get with the TP-Link Kasa Filament Smart Bulb KL50.  

The app opens to a My Family screen with panels for all of your installed Treatlife devices. The bulb panel displays the name of the bulb and has buttons for Power, Brightness, and Color Temperature. Tapping the Brightness button launches a slider for raising and lowering the brightness level, and tapping the Color Temperature button opens a slider that lets you adjust white temperature levels. Tapping the bulb icon opens a Dimmer screen where you can select one of four white temperature presets, or use the white color wheel to select a custom temperature. Swipe to the right to open a Color screen with blue, green, orange, and red presets, as well as a color wheel that lets you create a custom light color.

At the bottom of the screen are buttons for On/Off, Dimmer, Scene, Music, and More buttons. The Dimmer button takes you to the above-mentioned Dimmer screen, and the Scene button takes you to a screen where you can select from preset light settings including Night (reddish-orange), Read (bright white), Working (cool white), Leisure (warm white), Soft (green), Colorful (changing greens, blues, yellows, and reds), Dazzling (changing red, green, blue), and Gorgeous (fades from blue to yellow to green).

Tap the Music button to have the app access your phone’s microphone and change the bulb’s color in time to any music that's being played, and tap the More button to create on/off schedules and to use the countdown timer.

There are a few buttons at the bottom edge of the My Family screen. The Smart button opens a screen where you can create Tap-to-Run controls that let you do things like change colors or switch to a specific white temperature setting with the touch of a button. You can have these buttons appear at the top of the My Family screen for fast and easy access. You can also create automations to have the bulb react to weather conditions and when your location changes, and you can have it turn off at sunrise and on at sunset, or react to other Treatlife devices. Finally, the Profile button allows you to access account settings, edit your home information, run a network diagnostic utility, and log out of the app.

Installing and Using the Treatlife Bulb

Installing the Treatlife bulb is easy. I already had the mobile app installed from a previous review, but if this is your first Treatlife device, you’ll have to download the app and create an account.

I screwed the bulb into a lamp fixture, turned on the lamp, and the bulb began to blink. I tapped the plus icon in the upper right corner of the app, selected Smart Bulb from the list, and confirmed that the bulb was blinking. I was prompted to select my Wi-Fi SSID and enter my password, and within 15 seconds the bulb was connected. I gave it a name and the installation was complete.  

The Treatlife bulb delivered robust colors in testing. Whites were appropriately soft and yellowish at the low end (warm) of the temperature spectrum, and bright and bluish at the high end (cool). The bulb reacted instantly to app commands, and I had no trouble turning it on and off, changing colors, and adjusting brightness levels using Alexa voice commands. 

A Super-Affordable Color Smart Bulb

With the Treatlife Smart Wi-Fi Color LED Bulb, you can create mood lighting with millions of colors and a wide range of white color temperatures without spending a bundle. It has its own Wi-Fi radio and doesn't require a hub, and you can change colors and turn it on and off using Alexa and Google voice commands. At less than $10 per bulb when purchased in a pack, it's a fantastic value, even if it doesn’t integrate with third-party smart devices. If you want a full-color smart bulb that works with devices such as cameras, motion sensors, and door locks, consider the Yee Smart LED Bulb. It’s more expensive than the Treatlife bulb, but it uses IFTTT applets, works with Alexa, Google, and Siri voice commands, and supports the Apple HomeKit and SmartThings home automation platforms.
