LED strips

What are smart LED strips and what sets them apart from standard ones?

A standard LED strip emits a single colour or colour temperature and offers no remote control. A smart LED strip connects to an app via WiFi, Bluetooth or ZigBee, allowing you to change colour from 16 million options, set schedules, sync light to music and integrate with voice assistants. Smart strips have a built-in controller or use an external one.

RGB, RGBW and RGBIC — differences worth knowing

The most common type is the RGB strip with red, green and blue LEDs. The entire segment glows one colour at any given moment. RGBW strips add a separate white LED, producing a clean, neutral white without colour cast (pure RGB white always looks slightly purple).

The most advanced type is RGBIC (IC = Integrated Circuit). Each few-centimetre segment of the strip has its own control circuit, meaning different sections can glow different colours simultaneously. Rainbow wave, fire effect, alternating stair colours — these are only possible with RGBIC. RGBIC models in the homescreen.pl range include Yeelight Lightstrip Plus, Lightstrip 1S and Sonoff L3 Pro.

Smart LED strip applications

• TV backlighting (bias lighting) — a strip behind the TV reduces contrast between the bright screen and the dark wall, reducing eye fatigue during long viewing sessions. BlitzWolf BW-LB2 is designed specifically for TVs. Ambient mode syncs to the screen colour for a cinema effect.
• Furniture and cabinet underlighting — under kitchen cabinets, behind wardrobes, under the bed as night lighting. Warm 2700–3000K for kitchens, RGB for bedrooms with a night mode effect.
• Stairs — LED strips with a motion sensor for step-by-step stair lighting. Sonoff L2 with the SNZB-03 sensor creates an automation: each step lights up sequentially when motion is detected at the bottom.
• Outdoor use — moisture-resistant strips (IP65 or IP67) for facades, gazebos and gardens. Sonoff L2 and BlitzWolf BW-LT11 are available in outdoor versions.
• Gaming setup — a strip behind the monitor or desk synchronised with the game via Razer Chroma or the music mode in the app.

How to install LED strips?

Every smart strip has 3M adhesive tape on the back — just clean the surface and stick it on. For a permanent installation over longer runs, aluminium LED profiles with a diffuser are recommended; they spread light evenly and protect the strip from overheating.

Important rule: LED strips can only be cut at designated points (marked with scissors or a cut line), usually every 3 LEDs (approx. 5–10 cm). Do not cut RGBIC strips at arbitrary points.

Control: app, voice, music sync

Yeelight strips are controlled via the Yeelight app with built-in scenes and a music mode (phone microphone analyses the beat). Sonoff via eWeLink with schedules and timers. Gosund and BlitzWolf via Tuya/Smart Life with Google Home and Alexa integration.

Meross MSL320 is the only strip in this category supporting Apple HomeKit, allowing Siri control and iOS automations. If you are in the Apple ecosystem, this is the right choice.

Lengths and extensions

Most strips are sold in 2 m and 5 m lengths. Yeelight Lightstrip Plus extends with 1 m add-on segments. Sonoff L2 extends via L1. The maximum length per circuit depends on the power supply and is typically 5–10 m — for longer installations a second power supply or signal amplifier is needed.

Other smart home categories: smart home sensors, smart sockets, wall switches, IP cameras, home automation.

FAQ — Frequently asked questions

How long an LED strip for a room?

2 m is enough to backlight a 55-inch TV. To run a strip around the perimeter of a 4×5 m room ceiling you need approx. 18–20 m with two power supplies. For a 160 cm desk and wardrobe, one 3–5 m run is sufficient. Remember that RGBIC strips cannot be freely joined to any strip — use the manufacturer's original extension segments.

Are smart LED strips energy efficient?

Yes. A typical 5 m LED strip at full brightness draws 12–18 W, less than a standard 60 W bulb. In night mode at low brightness, draw drops to 2–5 W. The schedule function automatically turns the strip off at night, eliminating standby consumption.

RGBIC or RGB strip — which to choose?

Choose RGBIC if you want multi-colour effects simultaneously (rainbow, wave, gradient). RGB is sufficient for decorative single-colour backlighting and costs less. For TV backlighting, RGBIC produces a better bias lighting effect as the colour automatically adapts to different areas of the screen. For simple underlighting of furniture, standard RGB or RGBW is enough.
