Review: Easy to control lighting for anywhere - Super easy to install, I mounted behind my tv on my mantle. I’ve got it connected to Alexa so I can easily control it. Lights are bright and can handle just about any color. The adhesive is plenty sticky enough for my purposes. I’m a fan

Adhesive will hold as long as theres no weight pulling down. Not super long size-wise but its enough for desk backlighting.

## Questions & Answers

**Q: Why can't the extension clips be used so you can run a small section to one cabinet, extension wires behind to another, and extend with more lights?**
A: Sounds like you want to cut the one length into various sections and use multiple extension wires.  The answer is yes.  See my video which is looking 'up' at the underside of the kitchen cabinets. I used these https://www.amazon.com/gp/product/B072KRCJLD and cut them and added more length to them.  I even created 'Y' splits to put more light shining down. If you have a heat gun and like the wire connectors, I used https://www.amazon.com/gp/product/B07HCNTZ2Z

**Q: How many lumens are these? Please do not answer "I don't know" as that is useless; only answer if you know the answer!**
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.

**Q: why don't you show the power supply in the pictures?**
A: Power supplies are ugly, maybe? It's a standard "wall wart" type of supply. It's black.

**Q: I want to stick it behind my tv, can i cut it to make corners and reattach them with the l connectors?**
A: To make a 90 degree corner without cutting or soldering:
1. Say you are starting on the left side of the TV (from the back of the TV) going vertically up the back of the TV and want to make a 90 degree turn to the right.
2. At the turning point, make a 45 degree bend to where the LED side is facing away from you and the unattached portion of the strip is now pointing to the left.
3. Then do a 90 degree bend so it comes back over the 45 bend and is now going to the right as desired and the LED side will be facing the same side.
(Reach out if that isn't entirely clear.)

### ⭐⭐⭐⭐ Nice lights!
*by B***I on November 29, 2025*

This was great LED. I wish it was a little bit brighter. It was unfortunate that they did not have connectors that you could buy so I had to purchase them through Amazon. Overall easy to attach very happy with it being integrated into the Kasa app.
