Description

The Knightsbridge 24V RGBW LED strip light delivers colour-changing RGB plus a dedicated daylight white 6000K channel in a single 3m flexible strip. The strip measures 12mm wide and 1.8mm thick, with 36 x 5050 SMD LEDs per metre arranged in 166mm cuttable sections, allowing the strip to be trimmed to exact lengths during installation.

Designed for accent lighting, feature walls, under-cabinet lighting, cove lighting and architectural detail, the strip operates on 24V DC low-voltage and requires a separate constant-voltage driver and RGB controller (both sold separately). The RGBW configuration means the strip can produce full colour effects via the RGB diodes or switch to the dedicated white channel for task or ambient lighting at 6000K. The strip includes 3M self-adhesive backing for surface mounting to plaster, timber, metal and MDF substrates.

The IP20 rating limits the strip to dry indoor locations only — it is not suitable for bathrooms, outdoor use or damp environments. Maximum continuous run length is 10m before voltage drop reduces brightness and colour accuracy, so installations longer than 10m require separate driver feeds. The strip draws 9W per metre (27W total for the 3m length) and delivers 260 lumens per metre with a CRI of 85+, giving accurate colour rendering under the white channel. The 120-degree beam angle provides wide light spread from the flat strip profile.

Knightsbridge produces a full range of compatible drivers, RGB controllers, connectors and aluminium mounting profiles sold separately. The strip is also available in 1m, 5m and 30m reel lengths under the same product family.

Frequently Asked

What driver and controller do I need?

The strip requires a 24V DC constant-voltage LED driver rated for at least 27W (9W per metre × 3m). You also need a separate RGBW controller and remote to control colour changes and dimming. Knightsbridge produces compatible drivers and controllers sold separately at Niori.

Can this be used in bathrooms or outdoors?

No. The IP20 rating means this strip is for dry indoor locations only. For bathrooms, wet rooms or outdoor installations, use an IP65 or IP67 rated strip instead.

Can the strip be cut to shorter lengths?

Yes. The strip has cut marks every 166mm along its length, allowing it to be trimmed with scissors to exact measurements. Only cut at the marked sections to avoid damaging the circuit.

How long can a single run be?

Maximum continuous run is 10m before voltage drop causes dimming and colour shift. Installations longer than 10m need separate driver feeds or parallel wiring from a distribution point.
