Shenzhen, China – September 2026

ElisaCustom is pleased to announce the release of our new Waterproof SOB (Side-of-Board) LED Strip Series, now available in both low‑voltage (DC) and high‑voltage AC (line voltage) versions.

Designed for demanding indoor and outdoor applications, this new series combines the compact form factor of SOB technology with robust waterproof protection.


What Is SOB Technology?

SOB (Side‑of‑Board) is an innovative LED packaging method where chips are mounted along the side edge of the PCB, rather than on the top surface. This design offers several advantages:

Feature

Benefit

Ultra‑narrow profile

PCB width as slim as 8mm

Side‑emitting light

Ideal for edge‑lit applications and tight spaces

Uniform illumination

Smooth light distribution with minimal hotspots

The new waterproof SOB series takes this technology further by adding reliable moisture protection for outdoor and damp‑environment use.

Waterproof

Yes (SOB waterproof process)

Key advantage of the high‑voltage version: No external driver required. The strip can be connected directly to AC mains power, significantly simplifying installation for large‑scale projects.


Key Features

1. Ultra‑Narrow 8mm Width

The 8mm PCB width allows installation in tight spaces where standard LED strips cannot fit — such as thin cabinet edges, narrow channels, and slim architectural accents.

2. Waterproof Protection

Both versions feature our proprietary waterproof SOB process, protecting the LEDs and circuitry from moisture, dust, and splashing. This makes them suitable for:

  • Outdoor signage

  • Bathroom and kitchen lighting

  • Covered patio installations

  • Damp industrial environments

3. High‑Voltage Option: Driver‑Free Operation

The AC220V version eliminates the need for an external power supply. Connect directly to mains power using the included high‑voltage quick connector.

Benefit

Why It Matters

Simpler installation

Fewer components to mount and wire

Lower system cost

No driver purchase required

Longer runs

Supports up to 50 meters in a single run

4. Multiple Color Temperature Options

Available in three standard color temperatures:

Color Temperature

Appearance

3000K

Warm white — cozy, inviting

4000K

Neutral white — clean, natural

6500K

Cool white — bright, energetic

CRI options of ≥70 or ≥80 ensure good color rendering for most applications.


Applications

The new waterproof SOB series is suitable for a wide range of installations:

Application

Recommended Version

Cabinet and under‑shelf lighting

DC24V (safe, low voltage)

Signage and channel letters

Both versions (narrow 8mm width fits tight profiles)

Outdoor building outlines

AC220V (long runs, simpler wiring)

Bathroom vanity lighting

DC24V (safer in wet areas)

Retail display cases

Both versions (uniform side‑emission light)

Cove and accent lighting

DC24V (dimmable options available)


Why Choose SOB Over Traditional SMD?
