Product Information
Introducing our revolutionary 24V TM1934 Digital White LED Strip, engineered for exceptionally long runs up to 20 meters (65.6 feet) from a single power source. This digital led strip eliminates the common issue of voltage drop, ensuring consistent brightness and performance across its entire length.
For professional installers and ambitious DIYers, voltage drop is the primary challenge in large lighting projects. The TM1934 Digital White LED Strip directly solves this problem. Its innovative constant current architecture allows you to create stunning, 20-meter continuous lines of light without the need for complex wiring, multiple power supplies, or signal amplifiers. This drastically reduces installation time, cost, and potential points of failure.
Featuring high-quality SMD5050 LEDs and advanced TM1934 smart ICs, it allows for dynamic, individually addressable white lighting effects.
The dual-signal design provides enhanced reliability for permanent installations where maintenance is difficult, making it the perfect solution for large-scale architectural lighting, expansive cove installations, and commercial projects where seamless, uninterrupted lines of light are critical.
Simplify your wiring and achieve professional results with this super long run LED solution.
Key Features
Extended 20-Meter Run
Power a full 20m (65.6ft) reel from one end with no noticeable voltage drop or dimming.
Dynamic White Control
Each group of 6 LEDs is individually addressable via the TM1934 IC for creating chasing, flowing, and custom lighting effects.
Dual-Signal Redundancy
Features two data lines (DAT1, DAT2) for a more robust and reliable signal transmission, preventing failures down the line.

Frequently Asked Questions
Q: Can this 20-meter LED strip really run from a single power connection?
A: Yes. The integrated TM1934 constant current ICs eliminate voltage drop, allowing the entire 20-meter (65.6ft) length to be powered from one end with consistent brightness.
Q: What kind of controller do I need for this digital white strip?
A: You need a digital LED controller that supports the TM1934 IC protocol. Many universal SPI controllers are compatible. Always check the controller's specifications.
Q: What size power supply is required for the full 20-meter reel?
A: The full 20m reel consumes a maximum of 288W (20m x 14.4W/m). We strongly recommend a 24V DC power supply with at least 350W capacity to provide a 20% safety margin.
Q: Can I cut the strip to a custom length?
A: Yes, the strip can be cut every 6 LEDs, at the designated cut line marked on the PCB. The cut interval is every 10cm (approx. 3.94 inches).
Q: What is the purpose of the two data wires (dual signal)?
A: This strip has a primary data line and a backup data line. If one pixel (IC) fails, the signal automatically switches to the backup line to bypass the faulty point, ensuring the rest of the strip continues to work.
Q: Is the strip dimmable?
A: Yes, brightness can be controlled through a compatible TM1934 digital controller. Standard wall dimmers are not compatible.
