The SwitchBot RGBICWW Light Bars are a pair of colour-zone desk and TV lights that connect over Matter on Wi-Fi, with no SwitchBot Hub needed. SwitchBot announced them on 28 September 2026 at £55.99 in the UK, and they work with Home Assistant through the Matter integration.
What has changed with SwitchBot lighting?
SwitchBot's launch announcement describes a two-bar set. Each bar has six independently controllable colour zones, so the pair gives 12 zones across 16 million colours, plus dedicated warm and cool white LEDs covering 2200K to 6500K. Combined white output is up to 800 lumens, dimmable from 1% to 100%. SwitchBot lists 26 preset dynamic effects, and a built-in microphone drives six music-reactive modes without a separate sound sensor.
The headline change is connectivity. The bars use native Matter over Wi-Fi, so they pair directly with Apple Home, Alexa, Google Home, SmartThings, Home Assistant and Homey without a SwitchBot Hub. They are powered over USB-C, mount with built-in magnets or 3M adhesive, and the box includes desk stands, monitor mounts, a power cable and a wired controller cable.

Why does this matter for Home Assistant users?
It means you can add the light bars to Home Assistant locally with the Matter integration rather than relying on a cloud account or a bridge. Matter over Wi-Fi devices commission straight onto your network, and SwitchBot lists Home Assistant as a supported platform. Our Home Assistant Matter setup guide walks through adding a device by QR code.
The catch is feature depth. SwitchBot says zone settings, music sync, dynamic effects and certain advanced features are configured in the SwitchBot app, and that using the bars through Matter needs a compatible Matter controller. Our reading, not something SwitchBot has confirmed, is that Home Assistant will see a standard colour light with brightness and colour temperature, while the per-zone control and 26 effects stay in the app. We have not tested the bars yet, so treat that as an expectation to verify.

How do they compare with SwitchBot's other lights?
They extend a Matter-first lighting range rather than replacing anything. SwitchBot already sells an RGBICWW ceiling light, which we covered in our SwitchBot RGBICWW ceiling light review, and an RGBICWW LED strip. The bars suit shorter, desk-and-shelf jobs where a strip is awkward to mount. For bias lighting behind a TV, our Govee TV backlight review shows the alternative approach.
UK availability and price
The two-bar set is priced at £55.99 in the UK ($45.99 in the US) and is on sale through SwitchBot's own store and Amazon. Prices on Amazon can move and coupons come and go, so check the listing before buying.
Should you buy now or wait?
Buy now if you want a hub-free Matter colour light for a desk or TV and are happy to use the SwitchBot app for effects. Wait for independent reviews if per-zone control inside Home Assistant matters to you, because SwitchBot has not said which features Matter exposes. Brightness is quoted at ±20%, and the 800 lumens figure is for white light across both bars combined.
Frequently asked questions
- How much do the SwitchBot RGBICWW Light Bars cost in the UK?
- The SwitchBot RGBICWW Light Bars cost £55.99 in the UK for a set of two bars, according to SwitchBot's launch announcement, which also lists $45.99 in the United States. They are sold through SwitchBot's own online store and through Amazon. The box includes desk stands, monitor mounts, a power cable, a wired controller cable, fixings and 3M adhesive, so you should not need to buy accessories. One caveat is that retailer prices and coupons can change quickly in the first weeks after launch, so the £55.99 figure is the recommended retail price rather than a guaranteed shelf price. Check the current Amazon and SwitchBot listings before ordering, and compare against similar Matter lights if you only need one bar or a longer strip.
- Do the SwitchBot Light Bars work with Home Assistant?
- Yes, they should. The SwitchBot RGBICWW Light Bars use native Matter over Wi-Fi, and SwitchBot lists Home Assistant among the supported Matter platforms alongside Apple Home, Alexa, Google Home, SmartThings and Homey. You add them through the Matter integration by scanning the pairing code, with no SwitchBot Hub required. The caveat is feature depth: SwitchBot says zone settings, music sync, dynamic effects and certain advanced features are managed in the SwitchBot app. It is reasonable to expect Home Assistant to show a standard colour light with brightness, colour and colour temperature, but SwitchBot has not confirmed exactly which features Matter exposes, and we have not tested the bars ourselves. Check independent reviews before relying on per-zone control.
- Do the SwitchBot RGBICWW Light Bars need a hub?
- No. SwitchBot says the light bars use Matter over Wi-Fi and do not need a SwitchBot Hub for Matter connectivity, so they connect to your router like any other Wi-Fi device. However, to use them through Matter you still need a compatible Matter controller, such as a Home Assistant server, an Apple Home hub, a Google Nest speaker or an Amazon Echo that supports Matter. If you only use the SwitchBot app, the controller is not required. The practical caveat is that advanced lighting features, including zone control, music sync and the 26 dynamic effects, are set up in the SwitchBot app rather than through Matter, so most people will end up using both the app and their main smart home platform together.
›How we researched this
Claims in this article are checked against primary sources — manufacturer specifications, official documentation, Which? research, Ofgem guidance, or gov.uk — rather than forum threads or video reviews. Where the author has direct hands-on experience with a product (most Home Assistant, Zigbee, and home-networking gear is running in his own homelab), that is stated explicitly in the text.
For categories outside that personal setup — such as boilers, heat pumps, and other areas that are traditionally a heating engineer's domain — verdicts are built from cross-referenced manufacturer data, published lab results, and vetted expert and owner reviews rather than a claim of personal hands-on testing. See the editorial policy for the full methodology.
