Buying LED Strip Lights: A Guide to Choosing the Right Colour, Length, Controls and Safe Installation

An LED strip light can add decorative accents behind your television, beneath shelves, on kitchen furniture or in a gaming setup. However, having a wide range of options does not automatically make it easy to find the right product. LED light strips are often bought based on colour selection or price, while the power supply, IP rating and mounting surface are only considered later.

Before placing your order, check these three common purchasing issues:

  • Unclear length specifications: A 5 m LED strip will not automatically fit every wall or piece of furniture. Some sets also include cables, adapters or connecting leads, which may be included in the stated total length.
  • Confusing RGB, RGBIC and Tunable White: RGB creates blended coloured light. RGBIC can control several colour zones at the same time. Tunable White is designed to provide adjustable white light between warmer and cooler colour temperatures.
  • Overestimating adhesive strength: A self-adhesive LED strip will only adhere reliably to a clean, dry and preferably smooth surface. Dust, grease, rough walls or heat can affect adhesion.

These technical parameters are crucial before buying

1. Length, cuttability and mounting surface

Measure the required distance as accurately as possible before ordering. A 5-metre set may be sufficient for shelves or furniture, while TV backlighting depends primarily on the screen size and the recommended installation method.

The Govee Envisual TV Backlight T2 is designed for televisions measuring 55 to 65 inches. According to the product description, the LED strip should not be cut, as this could permanently damage the circuitry. The model is therefore designed for a specific TV size and is less flexible than a conventional cuttable LED light strip.

Also pay attention to the width of the strip, its bending radius and the position of the connecting cables. Sharp bends can damage conductive tracks and connections.

2. Power supply and energy consumption

An LED strip with power supply should be operated using the specified adapter. Check the following:

  • Input voltage, such as 100–240 V AC for sets with an adapter
  • Output voltage, for example 24 V DC
  • Power consumption in watts
  • Connection type, such as a mains plug or USB
  • Cable length and the position of the control unit

According to the product description, the 5-metre RGB set with 5050 SMD LEDs comes with a 24 V power supply and requires approximately 12 to 18 W. The Atmosphera model is specified as a mains-powered 230 V product with 22 W. The Govee TV set uses USB power, but operating the controller also requires the specified 12 V adapter.

You can estimate the approximate electricity costs by multiplying the power in kilowatts by the operating time in hours and your electricity tariff. A 20 W LED strip used for five hours a day consumes around 0.1 kWh per day. Actual consumption depends on brightness, colour mode and operating time.

3. IP rating and area of use

For living areas, IP20 is often sufficient for decorative LED lighting. However, this rating is not intended for use with water or in areas that are persistently damp. The LED strips mentioned here are designed for indoor use. In bathrooms, on uncovered patios or near sinks, only use products with an expressly suitable IP rating.

An LED strip with a remote control also needs a suitable position for the receiver and power supply. Adapters and control boxes should not be covered with textiles when placed in cramped, poorly ventilated compartments.

Why this product suits this profile: The set combines a 5 m length, RGB colours, an infrared remote control and a power supply. It is suitable for shelves, bedrooms, living areas or decorative lighting at parties.

How this product avoids the pitfall

The product description specifies the length, number of LEDs, voltage, power consumption and IP20 rating. This makes it easier to check the installation location and power supply before buying.

Main benefit & strengths

5 m length, 150 SMD LEDs, dimmable brightness according to the description and control via IR remote control.

Suitable for: Buyers with high quality standards
Tunable White LED Strip Light, Grey

Tunable White LED Strip Light, Grey

Why this product suits this profile: This OSRAM-FLEX-COB model is a good choice for users looking for adjustable white light rather than primarily coloured RGB lighting.

How this product avoids the pitfall

The selection clearly distinguishes between Tunable White and RGB. Before buying, users should nevertheless check whether the power supply, remote control and mounting materials are included in the desired delivery package.

Main benefit & strengths

5 m COB LED strip according to the product name and remote control according to the description.

Suitable for: Special applications & frequent users
Govee Envisual TV Backlight T2 with Dual Cameras

Govee Envisual TV Backlight T2 with Dual Cameras

Why this product suits this profile: This TV set is aimed at users with 55- to 65-inch televisions who want app, Wi-Fi and voice control, as well as colours that adapt to the content on screen.

How this product avoids the pitfall

Compatibility is limited to 55 to 65 inches, and according to the instructions, 5 GHz Wi-Fi is not supported. This information helps prevent unsuitable purchases for TVs of a different size or with a different network configuration.

Main benefit & strengths

RGBIC technology, two cameras, Govee Home app, Alexa and Google Assistant support, as well as music synchronisation according to the product description.

Suitable for: Flexible indoor design
LED Strip Light with Mains Plug, 5 m Long, Multicoloured Light and Remote Control

Installing and using LED strips without common mistakes

  1. Clean the surface: Remove dust and grease with a suitable lint-free cloth. The surface must be dry before you apply the strip.
  2. Plan the position beforehand: Mark corners and cable routes. The strip should not be under tension.
  3. Do not make sharp bends: Use the specified bending radius or suitable corner connectors, provided these are included with the set.
  4. Ensure the power supply is well ventilated: Adapters and control boxes must not be covered or operated in a cramped, warm compartment.
  5. Check the remote control: IR models require a clear line of sight to the receiver. App-controlled models, on the other hand, need a compatible Wi-Fi connection and the correct app.

LED strip light FAQ

How long does an LED strip light last?

Its service life depends on LED quality, heat dissipation, operating time, power supply and installation. A general lifespan cannot be stated reliably without specific manufacturer information. Do not leave the strip running permanently at maximum brightness and avoid heat build-up.

How much electricity does an LED light strip use?

Power consumption in watts is the key factor. A set rated at 12 to 18 W uses less energy over the same operating period than a 22 W model. Colour mode and brightness can affect actual consumption. An electricity meter is useful for obtaining a realistic estimate.

Can you cut any self-adhesive LED strip?

No. Only cut at clearly marked cutting points, and only if the product instructions permit it. According to the instructions, cutting the Govee Envisual TV Backlight T2 is not recommended. If you are unsure, install the strip without altering it.
