The length is generous enough to outline an entire room or wrap around multiple pieces of furniture. No need to buy extensions. Color accuracy and brightness are impressive. The RGB LEDs produce vibrant, saturated colors across the entire spectrum. Reds are actually red, not orange. Blues are deep and rich. The whites are clean without that bluish tint some strips have. Movie night, party mode, chill vibes. Whatever mood you want, these lights can create it. The Kasa app makes setup and control intuitive. Schedules, scenes, music sync, color presets. Everything you would want in smart lighting is available and works reliably. The wifi connection stays stable and commands respond instantly. No frustrating lag between tapping the app and seeing the lights change. Installation was simple with the included adhesive backing. Stuck firmly to my desk and entertainment center without peeling. The strip is flexible enough to follow corners and contours but rigid enough to not sag or droop. For anyone wanting smart RGB lighting that actually delivers on the smart features, this is it. The Kasa ecosystem is reliable, the lights are bright and colorful, and 32 feet is enough to do something substantial with. Review: Love this.

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.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 32 Feet of Smart RGB Lighting That Actually Integrates Seamlessly *by S***S on January 31, 2026* This LED light strip is 32.8 feet of RGB goodness that works with Alexa and Google Home and I am not going to lie, it completely transformed my room.

Love Kasa products. *by E***E on March 22, 2026* I already have a few of those around the house. I love it! Its so freaking easy to install. its totally plug and play. stick it, plug it in, pair it, done. it takes seconds to pair it with the Kasa app. I love Kasa products and have many ceiling lights, plugs, etc. of Kasa products. and it works flawlessly with Google Home, and Alexa. ### ⭐⭐⭐⭐ Decent LEDs for a good price *by L***8 on October 11, 2025* Great color and two strips work off one controller. I wish these were single LED addressable and had more effects or the very least each string could be controlled opposite the other, so red on one strip and green on the other. They work in Home Assistant which is helpful. ## Frequently Bought Together - Kasa Smart LED Light Strip, 16.4ft WiFi LED Strip Works with Alexa, Google Home, SmartThings, High Brightness with 16 Million Colors, RGB, Grouping, Adjustable Length, Up to 25,000 Hours (KL400L5) - Kasa Smart Light Bulbs, Full Color Changing Dimmable Smart WiFi Bulbs Compatible with Alexa and Google Home, A19, 9W 800 Lumens,2.4Ghz only, No Hub Required, 4 Count (Pack of 1), Multicolor (KL125P4) - Kasa Smart Plug HS103P4, Smart Home Wi-Fi Outlet Works with Alexa, Echo, Google Home & IFTTT, No Hub Required, Remote Control, 15 Amp, UL Certified, 4-Pack, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/347825610-kasa-smart-led-light-strip-16-4ft-wifi-led-strip](https://www.desertcart.it/products/347825610-kasa-smart-led-light-strip-16-4ft-wifi-led-strip) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
