## Summary description

Synergy21 S21-LED-NB00253 is a universal LED strip light powered by a 24 V AC adapter. It features 300 LEDs delivering multi-colour and warm white light options, suitable for accent, decorative and general lighting projects. Designed for indoor use, the flexible LED strip offers simple installation and energy-efficient illumination (energy class A).

## Long description

Synergy21 S21-LED-NB00253 is a flexible indoor LED strip that runs on a 24 V DC power source and contains 300 integrated LEDs. It provides both multi-colour (RGB) and warm white light options in a single strip, offering versatile illumination for accent, decorative and general lighting tasks. The product is energy-efficient and designed for simple installation in residential and commercial interiors.
Advantages
The strip combines colour-changing RGB capability with a dedicated warm white channel, allowing seamless transitions between multi-colour effects and warm white illumination. With 300 LEDs along a 5 m length, it delivers smooth light distribution and good colour rendering for accent lighting and backlighting applications. Low-voltage operation increases safety and energy efficiency, while the flexible format supports curved or linear mounting.
Suitable for
Accent and decorative lighting (shelving, coves, displays)
Backlighting for cabinets, TVs and signage
Ambient and indirect lighting in living rooms, bedrooms and hospitality spaces
Custom lighting projects that require colour change plus warm white
When it may not be suitable
This LED strip is intended for indoor use and has an IP20 rating, so it is not suitable for wet, damp or outdoor environments. It requires a compatible 24 V DC driver and an appropriate controller to access colour-changing and warm white functions; it will not operate directly from mains voltage without the correct power supply.
Key specifications
Voltage: 24 V DC
LED quantity: 300 LEDs
Length: 5000 mm (5 m)
Light options: RGB (multi-colour) plus warm white
Power consumption: 90 W (total strip)
Mounting: flexible strip suitable for linear or curved installation
Protection rating: IP20 (indoor use)
Energy efficiency: energy class A
How to use
Install the strip on a clean, dry surface using the adhesive backing or compatible mounting clips. Connect the strip to a 24 V DC driver and a matching controller to enable colour-changing and warm white modes. Cut only at marked cut points if shorter lengths are required, and ensure correct polarity when making electrical connections. Avoid bending the strip sharply at LED points and maintain ventilation around the driver.
What to consider before purchase
Intended installation location — strip is IP20 and for indoor use only
Need for a 24 V DC driver and a compatible RGB+WW controller
Required length and whether multiple strips or connectors are needed
Mounting surface compatibility and whether additional clips are necessary
Usage recommendations
For consistent colour and brightness across long runs, use a properly rated 24 V driver sized for the strip’s 90 W total consumption and consider powering the strip from both ends for runs near the maximum length. Use a compatible RGB+WW controller to access both colour-changing effects and warm white dimming.
