APA107/HD107S Addressable LED Strips

How to Choose: APA107 vs. HD107S vs. HD108

While the technical specs show a clear progression in speed, the right choice for your individually addressable LED strip depends entirely on your project's demands, especially regarding video and color fidelity. All three use a two-wire (Clock and Data) SPI-like protocol, making them significantly faster and more reliable than single-wire strips like WS2812B, but they aren't interchangeable. Think of it as a good-better-best lineup for specific tasks.

The APA107 is a solid, cost-effective replacement for older APA102 or SK9822 strips. It's fast, with a 30MHz data rate, making it great for general-purpose animations and effects. However, its 9 kHz PWM frequency can sometimes be visible to high-shutter-speed cameras, which might be a deal-breaker for video work. For most DIY projects, it's perfectly capable.

The HD107S is our go-to recommendation for almost any new design. It boosts the PWM frequency to over 26 kHz, completely eliminating any visible flicker for video recording or persistence-of-vision (POV) displays. With a 40MHz data rate, it's one of the fastest addressable RGB LED options available. We even stock the bare HD107S in 2020 SMD packages, allowing for custom, ultra-high-density PCB designs. If you're building anything that will be filmed, the HD107S is the minimum standard.

The HD108 is the specialist for when color accuracy is paramount. While it shares the high PWM and data rate of the HD107S, its killer feature is 16-bit color depth. This means it can produce 65,536 brightness levels for each color, compared to the 256 levels of 8-bit strips. The result is exceptionally smooth gradients and subtle color transitions, crucial for professional studio lighting, video walls, and high-end architectural installations. For most applications, 8-bit color is sufficient, but for broadcast-quality visuals, the HD108 is in a class of its own.

Why Choose a Two-Wire (CLK/DAT) Individually Addressable LED Strip?

The key difference between this family of addressable RGB LED strips and more common single-wire types like WS2812B IC strips is the second wire. Instead of embedding the timing signal into the data line, these strips use a separate clock (CLK) line. This architecture is a major advantage for high-performance applications. Because the microcontroller doesn't have to generate a perfectly timed data signal, it's free to work on other tasks, and the data transmission itself is much more robust against noise and voltage variations.

The practical result is that you can drive these strips at much higher speeds with far greater reliability. This is essential for large-scale projects with hundreds or thousands of LEDs, or for high-speed effects like light painting and persistence-of-vision (POV) displays where every microsecond counts. 

Power and Control for Your Addressable LED Strip Light

Properly powering your rgb addressable led lights is critical for performance and safety. All APA107, HD107S, and HD108 strips are DC5V. This low voltage requires careful planning to avoid issues, especially on runs longer than a few meters. We carry a full range of certified Mean Well 5V power supplies to handle any size project.

For control, any microcontroller that can output an SPI signal (like an ESP32, Teensy, or Arduino) will work well with popular libraries like FastLED. For larger, permanent installations, consider using a dedicated DMX to SPI decoder, which allows you to integrate your individually addressable led strip lights into a professional DMX512 lighting network.
