Kasa Smart LED Light Strip, 50 Color Zones RGBIC, 16.4ft Wi-Fi LED Strip Works w/ Alexa, Google Home & SmartThings, High Brightness, 16M Colors, PU Coating, Trimmable, 2 Yr Warranty (KL420L5)

This light strip is ridiculously vibrant. 50 color zones? I didn’t even know I needed that. Syncs with Alexa and Google like a charm.✔ Tip: Download the Kasa app for full control. It’s got pre-made moods like “Movie Night” and “Party” that slap.

Works as advertised. The product in question is solid and works. What I would have liked is to have the ability to take the left over strip and use an additional connector and power it elsewhere, but I realize that it isn't possible given that there is only one controller chip on the string, any additional chips would raise the cost.I am hoping that in the Kasa app to configure the light strip, I would get to not just have to use the color wheel to select the color, but with the Kasa bulbs, be able to choose presets like warm white for the strip.

This light strip was purchased to replaced my Govee LED strip installed as a TV halo on my 65" LG. Since an update earlier this year, the Govee app has made connecting the strip to Wi-Fi impossible. Not to mention, the Govee app is just horrible in general. It was time to let it go, so I bought this Kasa Smart LED strip.I already had a Kasa Smart light bulb which works perfectly and whose accompanying app is simple, clean and, best of all, works. It was no-brainer to go with Kasa this time for the LED strip.Good: It's bright.Has more color options than the Govee.Seems very well made.The app is pleasant to use.Not-so-good: The PU coating on the strip makes it VERY difficult to bend in a 90 degree turn, such as when lighting the rear perimeter of a TV. It is too thick to bend into a right angle at corners without protruding far out from the surface.And, because it doesn't bend well, the not-very-good adhesive keeps lifting away as the strip gets near the corner. Every time I walk by the TV, I reach back and press the strip down hoping one day it will just stay put all the way.Also not very good is when the light strip is dimmed. I usually keep it in a soft white color (about 4000 kelvin color temperature) and at 100% brightness. When I dim it to about 15% for, say, movies, or whatever, it goes from 4000k to 1000k, which is really orange-looking. The crappy aforementioned Govee did not do this. It handled maintaining color temperature well when it was dimmed. I was bit surprised this seemingly higher quality LED strip did this.Other than those things, it is a well-made strip with a good app, so I will keep it until I find a better LED strip at around the $20-$40 price range.

I recently built myself a house and have 7 of these light strips installed in various places, mostly as uplighting. I'm generally really happy with them but had a frustrating time with installation. I'll break this into installation and functionality / app interface.Install: For a normal use case, installation really couldn't be easier. The app walks you through step by step and has never failed me. But I had unusual circumstances, and these Kasa lights weren't well designed for going off-script. I have a 12V transformer in my utility room that feeds power to all my LED strips, allowing me to have them all on one switch, controllable by anyone who doesn't have my phone. I found that if I accidentally reversed the polarity of the wires when wiring power to the controller modules, the modules burned out instantly. This is an absolutely trivial thing to protect against on a circuit board, costing mere pennies in additional diodes/hardware. Thumbs down for cheaping out on this.The LED strips also failed where I needed to solder in an extension between the controller and strip (because the strip was located more than a few feet away from the power supply). This strip now works on solid colors but flickers when switching colors, so I can't run effects on it. Again, this won't affect most users but if your use case requires cutting and extending any part of the wiring, don't expect these to perform properly.App control: incredibly responsive. Most of the time lights turn on/off instantly. I also have a bunch of Kasa bulbs, switches, and smart plugs, and they all work perfectly. Coming from a 1st generation Hue system (absolutely terrible reliability), Kasa leaves little to be desired. Here's what I wish they would change:1. All my lights are scheduled to turn on some number of minutes after sunset, which I love. But the app only allows you to turn them on/off up to 59 minutes before/after sunset/sunrise. Why not add an hours wheel so you can have them turn off, say, 4 hours after sunset?2. The claim of 16 million colors is a joke. Not that these 16-bit RGB LEDs aren't capable of it, but the app interface limits the color options profoundly. With a 2" color wheel on the app and a 3/4"-wide index finger, I'd be surprised if I could select more than 100 different colors. Until Kasa adds a 0-255 RGB slider interface, their "16 million" claim is more than a little disingenuous.
