From the product details,

I just installed this on my 65" TV in the bedroom. It is very bright, so bright that I've had to lower the brightness down to 50% sometimes 30%. It pairs easily with Alexa and can be controlled with voice commands. Kasa is supposed to push an update which would allow this to sync to music (hoping it happens). My only gripe is lack of USB connection - this would have allowed me to connect directly to TV for synced lights on and off.

I also purchased a Govee brand during the BF, CM sale. The lights were weaker and found it to be unstable. I ended up putting those on my 32" monitor. Brightness is meh. I would go all Kasa next time.

From Amazon q&a

Since the KL400 doesn't utilize white LEDs, there is no technically no measured value of lumens.

However, since the KL400 can simulate white light using color combinations via its RGB LED technology, the brightness of this value is equivalent to 400 lumens.

150 "light sources" (from their product specs)
16.4 ft long (from their product specs)
One LED 1 every 1.31 inches.

16.4 feet
16 x 12 = 192
.4 feet = 4.8 inches (round up to 5)
192 + 5 = 197 inches

197 / 150 = one LED every 1.31 inches

You can decide if that's "big."

150/5m is on the "big gap" side. 300/5m is what you'd expect for small gap use. Wi-Fi LED strips should be under $10 any day every day, compatible with smart life.

here, this one's even RGBIC for $9:

or twice as long (10m/32') for $10:

(no affiliation, I just searched "wifi led strips" on Amazon and sorted by price)

Probably the cheapest this has been, waiting for the 32.8' to go back to $25, that was a better deal IMO.

How do these stick to walls? Adhesive? Will the wall paint come off if removing to reposition - and is the adhesive reusable multiple times?

What happens if the adhesive is not reusable? Will these be useless?

I used command hooks to stick it around a frame. It does have 3m adhesive on the back but didnt want to chance it messing up the paint or not being removable.

I haven't used the Kasa specifically, but I got the Govee product (https://www.amazon.com/gp/product/B07N1CMGQQ) a couple years ago, and it's been on three different TVs. The adhesive is pretty sticky, but comes up clean. It probably can take a handful of swaps as you slowly pull it up from your TV, but not indefinitely.

If you really wanted, you could just tape it to the back of your TV, which is pretty much what it's doing anyway.

Another noob question. How do you get LED strips like these to exactly match the length of the place that you want to put them on?

I imagine it would be just coincidence and luck if it "happened" to match out of the box. Right?

your only concern is if it's long enough. if it's too long, you just cut the end no problem.
on the reverse, you can also get connectors/extenders.
