Buy from B&H. Works easily with Alexa app

By Jennifer
Rated 5 out of 5
Date: 2026-05-20

Customer experience at B&H (in store) was superb. These bulbs are in my outdoor porch lights set to a warm low white that comes on at six pm and goes off at ten. Far better than 'solar' lights that shine too brightly all night long. these look like I'm home. Easy configuration of Kasa App with Alexa app - but you need a 2.4 gHz wifi, not 5 gHz. Good price at B&H.

Fun, convenient, quality.

I bought 8 of these bulbs (two packs) and have replaced all of the lamps in my house with them. they are convenient and the app works well. They are bright and have good color quality. It is nice to be able to dim each bulb individually. I can see myself buying more if my current supply ever runs out.

Is there a group feature that does more than just on/off, change colors etc? Can automation alternate colors for seasons like Christmas?

The TP-Link KL125 Kasa Smart Wi-Fi Light Bulb is an LED bulb that you can choose which color to change the bulb to. You can also create a group of bulbs to change colors at the same time.

Asked by: Levi
No, the bulb does not use a bayonet style base. It utilizes an A19 screw-type base.
