Universal LED strip light Synergy21 S21-LED-NB00253 24V, 300 LEDs, multi/warm white

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.
