What is an SPI LED Strip?

An SPI LED strip is a digitally addressable lighting solution that uses SPI (Serial Peripheral Interface) protocol to enable pixel-level control and synchronized dynamic effects. It is ideal for signage, stage lighting, architectural accents, gaming setups, and other applications requiring customizable and vibrant light animations.

The strip operates through clock (CLK) and data (DATA) lines, and requires an SPI-compatible controller to program individual segments or pixels with precise brightness and color effects.

The GL RGB SPI LED Strip features advanced WS2812 RGBIC technology, with each IC controlling 3 LEDs for segment-level chasing effects. It offers smooth color transitions, dynamic patterns, and adjustable brightness and speed—perfect for parties, commercial installations, and interior decorative lighting.

This model is designed for dry indoor locations, featuring a durable IP65 coating that provides basic protection from dust and accidental moisture exposure—but it is not rated for wet or submerged environments. It performs reliably in living spaces, retail settings, and controlled indoor environments.

Whether you're enhancing a retail display or creating ambient effects at home, this LED strip delivers high brightness, long lifespan, and flexible control to meet diverse lighting needs.(Click to see  How to apply 3M double-sided tape properly).

Specifications

Input Voltage × What is the input voltage of a low voltage LED strip light? GL LED low voltage strip lights are available in 12V or 24V DC. They require a compatible LED driver to convert standard 120V AC into safe low-voltage DC power. Using the wrong driver can lead to flickering, overheating, or permanent damage. Always match the power supply voltage to the LED strip’s rating. Proper voltage ensures consistent brightness, color accuracy, and a long lifespan. GL LED provides expert guidance and high-quality drivers for safe, efficient, and professional installations. Trust GL LED for reliable low voltage LED strip lighting solutions.	12VDC	LED Quantity × What Is LED Density (LEDs/ft)? This matters for exposed lighting—like under cabinets, shelves, or upscale interiors—where clean, even light gives a premium look. For example, our LEGEND series has 73 LEDs/ft, while COB offer 145–256 LEDs/ft for ultra-smooth, dot-free lighting. Choosing the right density ensures the best lighting quality and style.	18 LEDs/ft
Dimmable × Are LED strip lights dimmable? Yes, LED strip lights are dimmable. LEDs are naturally dimmable light sources. With a compatible power supply and dimmer, both single-color and color-changing strips can achieve smooth brightness control. GL LED offers a wide range of dimmable options, supporting PWM, Triac (forward phase), 0-10V, and ELV (reverse phase) dimming methods.Dimmable LED strips help save energy, extend lifespan, and create customizable lighting effects. GL LED helps customers select the right dimming system to ensure stable performance and meet specific lighting goals.	RGB SPI Controller	No Voltage Drop × What Is Voltage Drop in Low Voltage LED Strip Lights? Voltage drop happens when current loses strength due to resistance in wires or LED strips. It causes reduced brightness, color shifts, or flickering—especially at the far end. Always check the product specs. If the LED strip exceeds the max run length, connect another power feed to prevent uneven brightness.	16.4 ft Max
Lead Wire × What wire gauge (AWG) is used for low voltage LED strips? Wire gauge affects current capacity—lower numbers mean thicker wires. Choosing the right AWG prevents voltage drop, overheating, and fire risk, especially in long runs. At GL LED, most 12V/24V strips use 20 AWG, ideal for up to 10 ft and 5–11A loads. For longer runs or higher loads, 18 or 16 AWG is recommended to ensure brightness and safety. Read More >>>	20 AWG, 2ft (4 wires)	LED Chip/Control IC	5050/IC2812
Color	RGB	Operating Ambient Temperature	-13°F~104°F

Light Efficacy × What Is Light Efficacy (lm/W)? Does High lm/W Affect CRI? Light efficacy (lm/W) shows how efficiently electricity is turned into visible light. Higher lm/W means more light per watt, saving energy and reducing heat. But as lm/W increases, CRI (Color Rendering Index) often drops. High-efficacy lights may appear bright but show colors poorly. Industrial lights favor lm/W, while retail and home lighting value high CRI for accurate, natural color.	Up to 33 lm/W	Wavelength	Red: 620-625nm Green: 520-525nm Blue: 465-470nm
Power Consumption × What Is Low Voltage LED Strip Light Power Consumption (W/ft)? Power use is measured in watts per foot (W/ft) and depends on brightness, LED density, and color setup. To calculate total power: Watts = W/ft × total length (ft) When choosing a power supply, always add a safety margin: • Indoor: ×125% • Outdoor: ×150–200% This ensures stable, efficient performance and protects the driver from overload.	4.4 W/ft	IP Rating × LED Strip Light IP Rating Guide IP Rating = IP + Dustproof digit(0-6) + Waterproof digit(0-9) Examples(IP20 vs IP65 vs IP67 vs IP68): IP20-Not waterproof-Dry indoor areas IP65-Water resistant-Kitchen, bathroom, damp place(Complete dust-tightness and against low-pressure water jets) IP67-Temporary submersion-Outdoor(short-term water exposure) IP68-Continuous underwater-Pools, underwater lighting Pro Tip: Ensure waterproof connectors and buy from reputable brands to avoid fake ratings!
