Constant Current LED Strips

With over a decade of expertise in LED lighting, SUPERLIGHTINGLED 48V LED strip series is the ultimate solution for projects challenged by long-distance illumination requirements in white, CCT, RGB, RGBW, RGBCW light colors. Choosing 48 volt to run LED strip lights is great for large home and commercial projects. 

Due to good current planning, 48V led strip can run up to 60 meters. Typically, low voltage LED strips cause brightness degradation and color change due to voltage drop over long running distances. 48V LED lights can solve these problems very well. 48V, while higher than the common 12V or 24V, still meets safe voltage requirements.

Inline controller installation is the most common and user-friendly method for connecting LED strip lighting. In this direct current led 48V lighting setup, the LED strip is connected to the controller, which is then linked to the power supply. For 48V led light strip, a 48V controller and a 48V power supply are required, and their wattage and amperage must be sufficient to support the flexible led 48V light bar.

When your project needs more than the standard 5-meter (16.4 ft) roll, you hit a wall: voltage drop. The further the electricity travels, the dimmer the LEDs get, shifting a crisp white to a muddy yellow by the end. Our Ultra-long Constant Current LED Strips are the specific solution to this problem. Unlike standard LED strips that just use simple resistors, these are engineered with integrated circuits (ICs) and optimized circuit architectures that actively manage the power, guaranteeing perfectly consistent brightness and color on a single continuous run of 10m (32.8ft), 15m (49.2ft), 20m (65.6ft), 30m (98.4ft), or even up to 40m (131.2ft) at 24V or 36V DC. This is a fundamentally different approach than our DC 48V LED strips, which fight voltage drop by using a higher voltage. 

The LED brightness and the color keep the same at the beginning and the end, suitable for long LED lighting projects, simple wiring and cost less. We also offer IP20, IP65, IP67, IP68 waterproof ratings for each long led strip to suit your indoor and outdoor installation. There are various light colors you can choose from single colors to color changing RGB, RGBW, RGBCCT, and addressable pixel lights. 

Please Note: These ultra long led strip lights still need to be controlled by a constant voltage LED controller and power supply at the ends. 

When you need the absolute maximum amount of light for every watt you pay for, this is your category. SUPERLIGHTINGLED High Efficiency LED Strips are engineered for one primary goal: best-in-class luminous efficacy. While our ultra-long light strips focus on conquering voltage drop over 10+ meter runs, these are the sprinters, designed to deliver intense, high-quality light with staggering efficiency—often reaching 160 to 210 lumens per watt (lm/W). This is a huge leap from standard LED strips, which typically hover around 90-120 lm/W. You get 30-50% more brightness for the same power consumption, making them the most energy-efficient LED strip lights for demanding task lighting, high-ceiling coves, and commercial displays.

Constant Current vs Constant Voltage in LED Strips

It's all about control and stability. A constant voltage (CV) strip is wired in parallel; you send 24V down the line and each LED group takes what it gets. This works fine for shorter runs, but slight variations in manufacturing and temperature can cause some LEDs to run hotter and burn out faster. A constant current (CC) strip, however, adds a tiny brain for every few LEDs. This IC driver ensures that no matter what, the LEDs receive a stable, specified current (e.g., 40mA). This prevents thermal runaway, dramatically increases the LED's lifespan, and guarantees uniform brightness. 

Built-in Constant Current LED strips solve a problem many people don't notice until it's too late: visible components. While our other ultra-long constant current strips use external ICs on the circuit board to maintain brightness, this series integrates the constant current (CC) chip directly inside the 2835 SMD LED package itself. The result is a perfectly clean, minimalist look with no visible resistors or driver chips on the PCB. This design allows us to pack in more LEDs—up to 300 per meter—for a more uniform line of light and reduces the number of external components that could fail, increasing overall reliability.

What's the difference between a built-in IC and a standard LED current limiting resistor?

A standard LED current limiting resistor is a simple, passive component. It works by converting excess voltage into heat to protect the LED, but it can't adapt to changes. If your input voltage fluctuates or drops over a long run, the current delivered to the LED also drops, causing it to dim. A built-in constant current IC, by contrast, is an active circuit. It intelligently monitors and adjusts the power, ensuring each LED grouping receives the precise current it needs to operate at full, consistent brightness, regardless of its position on the strip or minor voltage sags. It's a smarter, more efficient way to power LEDs.

How does current in parallel and series circuits affect these strips?

In a standard LED strip, small groups of LEDs are wired in series, and then all those groups are wired in parallel along the strip's length. A common question is, is the current the same in a parallel circuit? In theory, yes, but in the real world of long LED strips, voltage drop says no. The groups farther from the power supply get less voltage, draw less current, and appear dimmer. Our built-in CC strips fix this at the source. The tiny IC integrated with each series group acts as a local regulator, ensuring that specific group pulls its rated current. This effectively neutralizes voltage drop's dimming effect, keeping the brightness identical from the first inch to the very last.
