Ultra-Long LED Strip Lights

Ultra-long LED strips are ideal for a variety of applications including architectural lighting, where they can outline buildings; event decoration, providing continuous lighting for parties and gatherings; and signage, illuminating letters and displays for visibility. They are also used in retail environments to enhance product displays and create an inviting atmosphere.

Not necessarily. Reel length is the amount of LED strip supplied on one reel. Maximum run length is the longest continuous section that can operate within the model’s specified performance limits under a defined wiring arrangement.

For example, a 50m reel does not automatically mean that all 50 metres can be powered from one end. That requires a model specifically designed for a 50m single-end run. Always check the rated run length and connection diagram when planning your installation.

Start with your required run length, light colour and brightness, then select a model that meets those requirements.

• 24V: A practical choice when you want to use existing 24V power supplies and controllers, provided the selected strip supports your required length.

• 36V: Consider this for models such as our 30m colour-changing and tunable white strips. Both the power supply and controller must support 36V operation.

• 48V: Consider this for the longest runs, including selected 50m white-light models.

At the same total power, a higher voltage means lower current. For example, a 240W load draws 10A at 24V or 5A at 48V. This can help reduce voltage loss in supply cables, but the strip’s rated run length still depends on its complete design.

Flickering can indicate several issues, such as an inadequate power supply, poor connections, or faulty LEDs. First, check the power supply to ensure it meets the required voltage and current. Then inspect all connections and wires for any signs of wear or damage. If flickering persists, consider testing individual sections to isolate the problem.

Selected 48V ultra-long LED strips can run up to 50 metres from a single-end power feed. The maximum length depends on the specific model, including its power consumption and circuit design—not voltage alone.

For shorter installations, our range also includes 24V and 36V options. Tell us your required continuous length, light colour and brightness, and we can recommend a suitable model and confirm whether it needs single-end, dual-end or additional power feeds.

To prevent voltage drop, use a sufficiently powerful power supply and consider injecting power at regular intervals, especially for longer runs. It’s also beneficial to use thicker gauge wire for longer connections, which can help reduce resistance and maintain a consistent voltage throughout the length of the strip.

Yes. Hanron can supply ultra-long LED strips cut to project lengths, with pre-fitted cables, connectors and waterproof end treatments to reduce on-site cutting and soldering.

We can customise cable length and size, connector type, and cable positions to match your installation. Finished strip lengths must follow the selected model’s cutting intervals, and waterproof connections must suit the intended environment.

Send us your required lengths, quantities, supply voltage, light colour, cable requirements and installation conditions. Our engineering team can then confirm the configuration and provide a quotation.

Use a constant-voltage DC power supply that matches the strip’s rated voltage, then calculate the total load:

Total strip power = Power per metre × Installed length

As a practical starting point, select a power supply that leaves approximately 20% of its rated capacity unused:

Required power supply capacity = Total strip power ÷ 0.8

For example, a 50m strip rated at 4.8W/m requires:

• Strip load: 50 × 4.8W = 240W

• Power supply capacity: 240W ÷ 0.8 = 300W

For a 48V version, this means a 48V constant-voltage power supply rated at least 300W, subject to its operating-temperature and derating requirements.

For RGBW and RGB+CCT strips, use the maximum power of the permitted lighting modes when calculating the load. Confirm whether the quoted W/m figure applies to one colour, white light or multiple channels operating together.

Use a compatible constant-voltage PWM LED controller with the correct output channels:

• RGBW: Four channels—red, green, blue and white.

• RGB+CCT: Five channels—red, green, blue, warm white and cool white.

Check the controller’s voltage range, current per channel, total current capacity and wiring compatibility. A controller rated only for 12–24V cannot be used with a 36V strip.

For example, if a 24V RGBW installation has a confirmed maximum load of 220W, its total current is:

220W ÷ 24V ≈ 9.2A

The controller must handle this total load with suitable headroom, and each channel must support its individual load. Do not assume the current is divided equally among the four channels.

RF, Wi-Fi, Zigbee or DMX control can be used with suitable equipment. For DMX systems, choose a compatible constant-voltage DMX decoder. If the load exceeds one controller’s capacity, use appropriately rated PWM amplifiers or divide the installation into controlled sections.
