What Is 36/48V Ultra Long LED Strip?

Also known as Super Long Constant Current LED Strip, this advanced linear lighting solution is designed to eliminate voltage drop over extensive distances.

By utilizing constant current ICs and thicker PCB designs, it ensures that when powered from just one end, the brightness remains perfectly uniform from the first meter to the last. Available in 20m, 30m, and up to 50m reels, it drastically reduces wiring complexity for large installations.

24V vs 48V Systems

Solving voltage drop in large-scale linear lighting.

24V

The Industry Standard

Highly versatile for general architectural lighting. However, inherent PCB resistance causes noticeable brightness degradation over distances.

Max Continuous Run 5 - 10 Meters
Power Double end power
Heat Generation Standard
Next Gen
48V

Engineered for Long run

Operating at 48V halves the electrical current compared to 24V, drastically minimizing heat and allowing extensive continuous runs.

Max Continuous Run 120M
Power Double end power
Electrical Current -50% Reduction
The Xmart Breakthrough

Frequently Asked Questions

What kind of power supply does the super long constant current LED strip need?

It requires a standard constant voltage power supply (24V, 36V, or 48V depending on the strip model). The constant current ICs on the strip itself handle the current regulation. Do NOT use a constant current driver.

Can the super long constant current LED strip be dimmed?

Yes, they are fully dimmable. They support PWM dimming methods including 0-10V, DALI, and TRIAC via compatible PWM controllers or dimmable power supplies. For optimal performance, a PWM frequency ≤ 2kHz is recommended.

What are the longest LED strip lights available?

With a single-end power input, our 48V constant current strips can reach 50 meters. If you power the strip from both ends (looping the power), you can achieve continuous runs of up to 100 meters without visible voltage drop.

Custom My 36/48V Ultra Long LED Strip

Constant Current Type
Choose between IC External (versatile, high power) or IC Built-in (narrow width, high density) based on your extrusion profile and dot-free requirements.
Voltage (24V / 36V / 48V)
