Transform your creative lighting projects with a kit designed to wow at first glow ✨. This next‑generation 1mm COB LED Driver Kit brings together ultra‑flexible 360° COB filaments 🔄, a smart 7‑channel hybrid output ⚙️, and rock‑solid power management 🔋—all in one compact board built for makers who refuse to settle for ordinary 🚀.

Whether you're crafting wearable light art 👗💡, cinematic ambient effects 🎬, model accents 🛠️, or custom prototypes 🧪, this kit delivers brilliant cool‑white illumination ❄️💡, buttery‑smooth dimming 🎚️, and multiple strip configurations that unlock a whole new level of creative freedom 🎨.

If you want lighting that’s sleek, stable, and stunning, this is the kit that makes your ideas shine brighter than ever 🌟.

 

✨ Features

🔌 Power Supply

When driving all channels simultaneously, the total current may exceed the limit of a standard computer USB port, which may cause flickering or dimming. In this case, please connect a 3.7V Li-Po battery or use a 5V/2A USB wall adapter for stable operation.

💡 Adapted for 1mm 3V COB LED Strips

This kit includes 5 different types of flexible COB LED strips (1mm width) designed for various project needs. The onboard hardware current limiting is precisely tuned for 3V COB strips, ensuring safe and stable performance.

⚙️ Strategic 7-Channel Hybrid Output

The board integrates 3 High-Power Channels (300mA) for bright illumination and 4 Low-Power Dimmable Channels (80mA) for breathing, fading, or ambient effects. One board manages both strong lighting and dynamic effects.

🌈 1mm Ultra-Flexible & 360° Cool White

The included filaments are made from flexible FPC and silicone phosphor, featuring an ultra-narrow 1mm width and providing a 360° full-angle glow. They output 6500K Cool White with CRI >80, offering smooth, dot-free, continuous lighting far superior to rigid LEDs.

🔧 Versatile Single & Double-Ended Designs

The kit supports both Single-Ended and Double-Ended COB strip structures. Single-ended strips allow clean wiring in tight spaces, while double-ended strips ensure uniform voltage distribution and consistent brightness across the entire strip.

At OpenELAB, we are committed to providing accurate product descriptions and high-quality electronics. The following policy outlines your rights and obligations, designed to be fair to both our customers and our business operations globally.

1. Warranty Policy

A. Standard Limited Warranty (Global & US)

For customers in the United States, Asia, and other non-EU regions:

  • Warranty Period: OpenELAB provides a 12-month warranty from the date of delivery.

  • Coverage: This warranty covers defects in material and workmanship under normal use.

  • Resolution: We will repair or replace defective units at no charge.

B. Statutory Rights for EU/UK Customers (EU Compliance)

If you are a consumer residing in the European Union or the UK purchasing from our global site:

  • Statutory Guarantee: You are entitled to a 24-month statutory guarantee for conformity defects present at the time of delivery, in accordance with EU consumer protection laws.

  • Relation: The Standard Limited Warranty (Section 1.A) applies in addition to, and does not replace, your statutory rights.

C. Warranty Exclusions (Applies to ALL Regions)

Warranty coverage is VOID if the damage is caused by:

  1. Misuse: Incorrect installation, reverse polarity, or exceeding voltage limits.

  2. Unauthorized Modification: This explicitly includes soldering, cutting pins, modifying the PCB, or flashing unauthorized/beta firmware that "bricks" the device.

  3. Physical Damage: Drops, moisture/water damage, or electrical surges (lightning).

  4. Normal Wear & Tear: Consumable parts (e.g., batteries), unless defective upon arrival.

Note: For non-warranty repairs (e.g., customer-induced damage), we may offer repair services for a fee. Shipping and diagnostic costs will be borne by the customer.

2. Return & Refund Policy

A. Return Window

  • Standard: You may request a return within 30 days of receiving your order.

  • EU Customers: You have the statutory right to withdraw from the contract within 14 days of receipt without giving a reason.

  • The item is Brand New, Unopened, and Unused.

  • The original packaging is intact and sealed.

  • All accessories are present.

2. Partial Refund (Restocking Fee / Value Depreciation)

Deductions apply if:

  • Signs of Use: Visible scratches, mounting marks on screw holes, or fingerprints.

  • Damaged Packaging: Original box is torn, written on, or missing.

  • Technical Modification: The device has been powered on, programmed/flashed, or soldered.

To ensure a smooth return process, please follow these steps:

  1. Authorization: Contact us at info@openelab.io before returning any item. Returns without prior authorization will not be accepted.

  2. RMA Number: We will provide you with a Return Merchandise Authorization (RMA) number and the correct return address.
