(all after 2016 support Bluetooth gateway Alexa Devices) Review: 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! Review: Stopped Working - App doesn't connect to the bulbs anymore. The bulbs disconnected for some reason and the app can locate them, but it can't connect. So now I have very expensive white bulbs. ## Features - Sengled S1 Auto Paring: (No registration required, No 3p account required) The Sengled Auto Pairing Kit offers a simple setup and stable links.
