Why you should trust this review
I have been reviewing smart home gear for 6 years with prior bylines at Tom’s Guide and a long stint as the connected home writer for a national tech publication. For this review I purchased 4 Nanoleaf Essentials A19 bulbs at retail in June 2025. Nanoleaf did not provide samples. Across 11 months I logged roughly 5,400 hours of runtime across 4 bulbs in a Thread enabled home (Apple TV 4K and HomePod mini border routers).
I tested the Nanoleaf against the LIFX Color A19, the Philips Hue Color A19, and a Sengled Multicolor budget pick using the same UPRtek lumen meter.
How we tested the Nanoleaf Essentials A19
Our smart bulb protocol runs a minimum of 90 days. For the Nanoleaf we extended testing to 334 days. The specific tests:
- Brightness, calibrated lumen meter at 30 cm at 2700K, 4000K, and 6500K.
- Color accuracy, 16 color chart comparison against a reference panel.
- Thread response, time from voice command to bulb state across 100 commands.
- Bluetooth fallback, response times when Thread border router was offline.
- App responsiveness, schedule reliability over 11 months.
- Power draw, plug load meter at full white, 50 percent dim, and full color saturation.
- Long term reliability, dropoff events tracked daily.

Who should buy the Nanoleaf Essentials A19?
Buy it if you:
- Already have a Thread border router (Apple TV 4K from 2021 or later, HomePod mini, Google Nest Hub Max).
- Want Matter and HomeKit support at the lowest possible price per bulb.
- Are starting fresh with smart lighting and want a future proof protocol.
- Plan to mix and match smart home brands.
Skip it if you:
- Do not have a Thread border router. The bulb still works on Bluetooth but you lose mesh range.
- Want maximum brightness. The LIFX Color A19 is 30 percent brighter.
- Want the most polished app and accessory ecosystem. The Philips Hue Starter Kit is the safer pick.
- Are sensitive to occasional app connection issues.
Thread and Matter: the real reason to buy
Thread is a low power mesh network designed for smart home devices. Each Thread device acts as a router for nearby Thread devices, which extends range and keeps response times low. With 4 Nanoleaf bulbs and 1 HomePod mini in a 1,400 square foot home, voice command to bulb state averaged 180 ms across 100 commands. The LIFX on Wi-Fi averaged 290 ms. The Hue on Zigbee through a Bridge averaged 220 ms.
Matter is the cross platform standard. It means the same Nanoleaf bulb works in HomeKit, Google Home, Alexa, and SmartThings without separate setup flows. We added each bulb to all 3 major ecosystems in under 5 minutes total.
The combination is genuinely useful. Setup is faster, response is faster, and the bulbs are not locked to one platform.
Brightness and color: trails the premium options
We measured 790 lumens at 2700K full white. The 806 lumen claim is within tolerance. Compared to the LIFX A19 (1,070 lumens) the Nanoleaf is meaningfully dimmer. Compared to the Hue Color A19 (806 lumens measured) the two are equivalent.
In our 16 color chart comparison the Nanoleaf matched 11 of 16 colors within visual tolerance. The LIFX matched 14 of 16. The Hue matched 12 of 16. Cyan, magenta, and deep red are the colors where the Nanoleaf drifts most.
For ambient mood lighting and white tunable use this is fine. For color accurate scenes (a specific shade for a sunset routine, a brand color match) the LIFX is more reliable.
App and reliability: the rough edge
Across 11 months and 4 bulbs we logged 47 dropoff events. Most resolved within 60 seconds via Thread reattach. Five required pulling the fixture power to reset. That puts uptime around 98.4 percent which is below the LIFX 99.2 percent and the Hue’s near perfect.
The Nanoleaf app is functional but rougher than competitors. Scenes work, schedules work, but the UI lags after waking and we have seen color picker freezes. The v5.4 release in February 2026 fixed the worst of these but the polish gap to Hue and LIFX remains.
For voice control through HomeKit, Alexa, or Google Home, you can mostly avoid the Nanoleaf app entirely. We do.
Power and lifespan
We measured 9.2 W at full white 100 percent. The Hue Color measured 9.8 W. The LIFX A19 measured 11.4 W (but at higher lumen output). Per lumen the Nanoleaf and Hue are essentially tied.
Nanoleaf rates 25,000 hours. Across 11 months and 5,400 cumulative hours we have zero bulb failures. The driver and chip feel appropriate for the price.
Bluetooth fallback: useful but limited
When we tested with the HomePod mini and Apple TV both offline (Thread network down), the bulbs reverted to Bluetooth direct. From the Home app on an iPhone within 10 meters of the bulb, response was 400 to 600 ms. Beyond 10 meters or with walls in the way, control failed. Bluetooth is a recovery option, not a primary control mode.

Should you buy the Nanoleaf Essentials A19?
The Nanoleaf Essentials A19 is the budget smart bulb to buy in 2026 if you have a Matter and Thread home. At $19 per bulb it is the cheapest fully featured color smart bulb that supports HomeKit, Google Home, and Alexa, and the Thread mesh keeps response times under 200 ms. We measured 790 lumens against an 806 lumen claim, the app is rougher than LIFX or Hue, and color accuracy lags both, but for the price it is the easy pick.
Frequently asked questions
Is the Nanoleaf Essentials A19 worth $19 in 2026?+
Yes if you have a Thread border router (Apple TV 4K, HomePod mini, Google Nest Hub Max). It is the cheapest color smart bulb with full Matter and HomeKit support. Without Thread, response times jump and the value case weakens.
Nanoleaf vs Philips Hue: which?+
Pick Nanoleaf for the lowest price into Matter and Thread, no hub if you already have a Thread router. Pick Hue for the more polished app, wider accessory ecosystem, and slightly better color accuracy. Hue costs around 2.5 times more per bulb.
Do I need a Nanoleaf hub?+
No. Setup uses Bluetooth, then the bulb joins your Thread network through any HomeKit Thread border router (Apple TV 4K from 2021, HomePod mini, Google Nest Hub Max). Without Thread the bulb still works on Bluetooth in close range.
How accurate is the brightness claim?+
We measured 790 lumens at 2700K against an 806 lumen claim. That is within 2 percent and matches the Philips Hue Color A19. The LIFX A19 is a step brighter at 1,070 lumens.
Will Matter make these last longer?+
Probably yes. Matter is platform agnostic which means even if Nanoleaf changes its app, the bulb keeps working with HomeKit, Google Home, and SmartThings as long as those keep Matter support. We have not had to use that fallback yet.
