Sengled Alexa Light Bulbs, 100W Equivalent, S1 Auto Pairing with Alexa Devices, Smart Light Bulb that Work with Alexa, Bluetooth Mesh Smart Home Lighting, ‎Multicolor Dimmable, No Hub Required,4-Pack

Works exactly the way I’d hoped, no extra app required
I could not for the life of me find reviews that talk about operating a smart bulb with a wall switch. Now that I’ve tested this one, I can do it.I have a lamp in my TV room controlled by a wall switch. I’m fine with that and want to keep it that way. That is, until I get comfortable on the couch with the cat sitting in my lap. I don’t want to have to get up and turn it off. That is where the Sengled bulb and the echo come in: “Alexa, Light 1 Off”.When I’m ready to leave the room I say “Alexa, Light 1 On”, and my way out of the formerly dark room is lit. Then, when I leave the room, I use the WALL switch to turn off the light as I’ve been used to doing for years. The next time I go to the room, I turn the light on with the WALL switch and it comes ON, which is what I wanted.Even better, it comes on at the brightness level it was last set for. I chose the 100W equivalent bulb which I normally run at about 50%. I get the same light level as the old bulb, but I have the option for more light when I need it (such as when cleaning). “Alexa, Light 1 to 100%”. I use that a lot.To be clear, this is the Bluetooth light that works only with Alexa. I’m okay with that as I’ve been an Echo user for a while now, and I’m already signed up. All of the other smart bulbs I considered need some app downloaded, an account set up, and linking the app to Amazon. I need that like a hole in the head.I absolutely love that this bulb can be set up without a third-party app. That is worth a few extra bucks to me. I was up and running in a couple of minutes. The setup isn’t totally glitch-free (largely due to the Alexa app) and Alexa sometimes says the light isn’t responding (even when it does). I can overlook that because it works anyway.I am so pleased, I bought additional 100W equivalent bulbs. One is over the dining table where I like it to be dim most of the time. It is great to be able to get more light on demand without using dimmer switches (which I don’t have). Finally, the Echo can do something of value other than play music.

Great Smart Bulbs !!!
After much research, I opted to buy a 4 pack of Sengled Alexa Light Bulbs, 100W Equivalent – for use in our bedroom. I also opted to purchase an Echo Dot (gen 5) to control them as Alexa voice commands to your phone will not work. The light bulb verbiage: “Alexa Only” along with “Bluetooth Mesh” signify the bulbs will work only via Bluetooth and not via WiFi. Also, if my WiFi is down or gets a weak signal – they continue to work. They pair too easy: screw them into a lamp, turn the lamp on, say “Alexa Discover Devices”, and about 30 seconds later the bulb (device) is added to Alexa’s list of devices and named “1st Lamp” and so on for the other bulbs. FYI: the bulb is referenced as “1st Lamp” or “Lamp 1”. Or you can rename it using the Alexa App. After I installed the other 3 lights – I used the Alexa App to group them and named the group “Lights” to work with the command “Alexa Lights On”. After the initial setup using the Alexa App – I use Alexa voice commands to adjust their color, brightness and temperature via group name or individual name. And, if I manually turn a light off – it returns to its last setting when manually turned on. Here is something most interesting: they also work in 3-way rotary switch lamps. Note that click-1 is the same as “off”, and click-2 and click-3 is “on” with no difference in brightness. I saw a couple reviews that stated these 100 watt equivalent bulbs (1500 lumens) were lacking in brightness – and found that was not true. Sengled has engineered a quality bulb and I will buy more because of their easy setup, overall functionality and 3 year warranty.Update 11-30-2024:1st problem after 10 month of daily usage. I lost almost all Alexa communications except off/on. I could not adjust color, temperature or percentage. However, it was an easy fix. I did not have to “reset” each bulb and “discover” them. I just turned all lights off via command. Then I disconnected the electric cord from the Echo Dot and waited about 30 seconds before reconnecting the cord. Then I waited about 1 minute until the time of day displayed. Then I gave a couple simple commands to Alexa to insure the Echo Dot was working. Then i gave Alexa numerous light commands to insure the problem was resolved. Too simple!

Muy conforme con el producto

Eccho 10.

Iluminan muy bien, mejor que otros y su configuración es muy fácil y rápida, directo desde la app de Alexa. El único pero es ese, que sólo son compatibles con Alexa. En el video, cambio su iluminación entre 100% y 1%. Nota: sólo es blanco, no es de colores.
