This Kasa smart color bulb with 16 million colors, Alexa and Google Home control, energy monitoring, scheduling, and auto white adjustment from warm to cool across 2500K to 6500K is $8 right now. Amazon has the TP-Link/Kasa KL125 model at $8, off its $11 standard price, for a Wi-Fi smart bulb that requires no hub, no bridge, and no additional hardware beyond a 2.4GHz WiFi network that already exists in virtually every home.
16 million colors, Alexa control, and no hub
The price comparison with a dumb bulb is the one that makes the Kasa KL125 bulb hard to walk past. A Philips standard A19 LED at equivalent brightness costs $8 to $10 on Amazon with no smart features, no app control, no voice control, and no scheduling. The Kasa at $8 delivers full RGB color across 16 million options, warm to cool white adjustment across the full 2500K to 6500K spectrum, Alexa and Google Home voice control, remote app control from anywhere, energy monitoring, sunrise and sunset scheduling, and timer automations, all without a hub or bridge. The smart version costs the same as the dumb version and does considerably more with it.
The Auto White mode adjusts color temperature automatically throughout the day to match natural light patterns, shifting from warm yellow in the morning to cool white during midday productivity hours and back to warm in the evening, which is the circadian lighting feature that dedicated smart lighting systems charge significantly more to implement. Voice control via Alexa or Google Home handles lights-on, lights-off, dimming, and color changes without touching a phone or switch, which covers the entering-a-dark-room and hands-full scenarios that make voice-controlled lighting genuinely useful rather than a novelty.
Energy monitoring tracks real-time power consumption, which lets users identify which lamps in the home draw the most power and schedule them to run only when needed. At 9W drawing 60W-equivalent brightness, the Kasa already saves power compared to the incandescent bulbs it replaces, and the scheduling feature extends those savings by automating off times for rooms that are frequently left lit without anyone in them. The Kasa app on iOS and Android manages all bulbs, schedules, and automations from a single interface without the separate hub that Philips Hue and LIFX require.
Pocket change for a smart bulb that out-features everything at this price
Kasa is trusted by over 6 million users, which reflects years of consistent Wi-Fi smart bulb performance rather than a single product cycle. The KL125 bulb is UL certified for safety use and backed by a 2-year warranty, which covers the full unit for longer than most smart bulb warranties at this price point. Setup requires the Kasa app and a 2.4GHz WiFi network: open the app, screw in the bulb, follow the three-step pairing process, and the bulb is live and controllable from anywhere with an internet connection.
For anyone building a smart home lighting setup on a budget, or anyone replacing existing bulbs and wondering whether to upgrade to smart while doing so, the Kasa KL125 bul at $8 makes the decision straightforward. The dumb bulb costs the same and does one thing. The smart bulb costs the same and does everything the dumb one does plus 16 million color options, voice control, scheduling, and energy monitoring.
