Kasa Smart Light Bulbs that works with Alexa and Google Home (KL110P4)
Quick take
Kasa’s KL110P4 A19 smart LED bulbs bring dimmable soft-white lighting, remote control through the Kasa app, and voice support for Alexa and Google Assistant without needing a hub. They’re best for everyday lamps and fixtures where you want smooth brightness control and scheduling, but they require a 2.4GHz Wi‑Fi network to connect.
Pros and cons
Pros
- Dimmable from 1% to 100%, useful for everything from “candlelight” to full brightness
- Works with Alexa and Google Assistant for hands-free voice control
- App remote control, including scheduling and timer-based automation
- Energy monitoring to track real-time usage
- Uses the standard E26 base and fits common A19 lamp sockets
Cons
- 2.4GHz Wi‑Fi only (not compatible with 5GHz-only setups)
- Some buyers note brightness expectations can vary depending on the space and desired look
What buyers think
Buyer-review evidence is generally positive around setup speed and day-to-day convenience. Multiple reviews describe the pairing process as straightforward, with the Kasa app guiding users through the steps, and voice control working as expected once connected. Reviews also tend to emphasize that the dimming behavior is smooth and that the soft-white 2700K color is a good match for bedrooms, dining rooms, and reading or general room lighting. A smaller theme is that brightness can be “plenty” for warm, comfortable lighting, though individual expectations for maximum brightness may differ by room and fixture.
What these Kasa smart bulbs are
The Kasa KL110P4 is a set of smart LED A19 bulbs (E26 base) designed for indoor use. They’re rated at 9W (about a 60W incandescent equivalent), produce up to 800 lumens, and deliver a soft white 2700K color temperature with a CRI of 90 or higher for more natural-looking light. The bulbs are designed to connect directly to your home Wi‑Fi (no hub required) and can be controlled via the Kasa app, plus voice control through Alexa and Google Assistant.
Key features that matter in daily use
Dimming from 1% to 100%
One of the biggest practical advantages is the wide dimming range, from very low levels up to full brightness. That makes these bulbs more flexible than non-dimmable smart bulbs when you want the same fixture to work for different moods and tasks.
Voice control and remote access
You can turn bulbs on and off, adjust brightness, and manage lighting from anywhere using the Kasa Smart app on iOS or Android. Voice control is supported through Amazon Alexa and Google Assistant, which is useful if you want hands-free lighting changes.
Energy monitoring and automation
These bulbs include energy monitoring, plus scheduling and timer options so your lights can automatically turn on and off. For many people, that’s the difference between “smart lighting for convenience” and “smart lighting that helps with routines,” like waking up to a gradual light schedule.
No-hub setup, with an important network requirement
These bulbs connect using Wi‑Fi, but only on 2.4GHz networks. If your home uses 5GHz-only Wi‑Fi, or if your network setup doesn’t support 2.4GHz, you’ll need to adjust your Wi‑Fi environment before buying.
Pros and cons breakdown (who it’s best for)
Best for
- People who want dimmable smart lighting for lamps and everyday fixtures (bedrooms, dining rooms, living rooms, reading nooks)
- Homes that already use Alexa or Google Assistant and want voice control
- Buyers who care about schedules and want to monitor energy use
- Anyone who prefers standard A19/E26 compatibility rather than specialty bulb formats
Who should avoid it
- Shoppers with only 5GHz Wi‑Fi (or who do not want to provide a 2.4GHz connection)
- People shopping primarily for maximum brightness at a “cool white” look, since this model is specifically soft white 2700K
Compatibility and setup checklist
- Bulb type and base: A19 shape, E26 base (fits most standard household lamp sockets)
- Brightness and color: 800 lumens, 2700K soft white, CRI 90+
- Dimming: adjustable from 1% to 100%
- Controls: Kasa app remote control, Alexa, Google Assistant
- Wi‑Fi requirement: 2.4GHz Wi‑Fi only
Verdict
If you want a hub-free smart bulb with smooth dimming, soft white 2700K lighting, app control, and voice support, the Kasa KL110P4 is a practical choice. The biggest potential dealbreaker is the 2.4GHz-only Wi‑Fi requirement, so it’s worth confirming your network setup before ordering.
