Current Market Landscape & Technical Pain Points in Colombia
The LED billboard market in Colombia is showing explosive growth in 2025, but investors are still plagued by three major issues: blurry image quality, low installation efficiency, and certification bottlenecks.
In Bogotá’s commercial district, an 80㎡ outdoor screen selected the wrong pixel pitch, resulting in poor daytime visibility. A shopping mall in Medellín faced a 15-day delay because the installation team lacked experience working in tropical climates. Even more challenging, 35% of imported LED display equipment gets held at port for failing RETIE electrical safety certification—costing up to $500 per day in storage fees.
As a factory deeply engaged in the Latin American market, Sostron has found that many Colombian buyers fall into a “spec-chasing” trap—23% of projects use P2.5 screens for a 5-meter viewing distance, wasting roughly 30% of the investment. In fact, based on the pixel-pitch selection formula (Optimal viewing distance = pixel pitch × 1000 / 0.3), a P3.91 screen is already sufficient for a 10-meter viewing distance.
Core Parameters & Price Comparison for Outdoor LED Billboards
Outdoor LED screens in Colombia typically range from R$543.80 to R$3,061.56 per square meter, depending on pixel pitch and performance. Below is a comparison of three Sostron products optimized for Colombia’s climate:
| Parameter | P2.6 (Indoor HD) | P4.81 (Standard Outdoor) | P6.67 (Long-Distance View) |
|---|---|---|---|
| Pixel pitch | 2.6mm | 4.81mm | 6.67mm |
| Brightness | 1200 cd/㎡ | 6500 cd/㎡ | 5500 cd/㎡ |
| Refresh rate | 3840Hz | 1920Hz | 1500Hz |
| Protection rating | IP54 | IP65 | IP65 |
| Avg. power | 280W/㎡ | 350W/㎡ | 300W/㎡ |
| Reference price | R$2,850/㎡ | R$1,680/㎡ | R$950/㎡ |
Key Technical Notes
Brightness:
Colombia’s equatorial sun reaches up to 80,000 lux at noon. Outdoor screens must reach ≥5000 cd/㎡ for visibility. Sostron’s pixel-level calibration ensures 97% brightness uniformity.
Refresh rate:
Screens installed along highways should use ≥1920Hz to avoid motion trails.
Protection:
Coastal cities face severe salt corrosion. Sostron’s nano-coating extends product life to 8 years.

SMD vs. COB: Technology Selection for the Colombian Market
Colombia commonly uses both SMD and COB LED technologies. Choosing the wrong approach can double long-term maintenance costs.
SMD (Surface-Mount Device)
-
Advantages:
High pixel density (P2.6 reaches 147,000 dots/㎡), excellent color reproduction (16-bit grayscale) -
Best for:
Malls, airport halls, mid- to short-distance viewing -
Example:
Bogotá El Dorado Airport T2 — P3.91 screen running 18 hours/day
COB (Chip-on-Board)
-
Advantages:
Impact-resistant (up to 5kg force), excellent moisture protection (IP68) -
Best for:
Coastal, rainy, and harsh outdoor environments -
Sostron breakthrough:
Dual COB + GOB encapsulation achieves Mohs 7 hardness—resists marker scratches.
Heat Dissipation Comparison
-
SMD: aluminum housing + fan cooling, ideal for −20°C to 50°C
-
COB: copper-pillar direct cooling; remains stable even under Colombia’s 38°C heat
Testing in Medellín shows COB P8 screens operate 12°C cooler and reduce failure rates by 62% compared with SMD.

Certification & Compliance Requirements in Colombia
LED billboards entering Colombia must pass three mandatory certifications. Missing any one of them can lead to product seizure and fines up to 2000× monthly salary (≈R$2.6 million).
RETIE (Electrical Safety)
-
Standard: NTC2050 (based on IEC60898)
-
Key tests: 2500V withstand test (1 min), insulation resistance ≥100MΩ
-
Sostron advantage: Recognized by the Ministry of Mines & Energy; approval time reduced to 45 days
CRC (Communications Compliance)
-
Applies to LED screens with wireless modules
-
Requirement: 2.4GHz EIRP ≤ 4W
-
Tip: Using FCC-approved Wi-Fi modules can qualify for partial test exemptions
RETILAP (Energy Efficiency)
-
7 grades from A++ to E; outdoor screens must meet Grade B or above
-
Label: Yellow background with black text
Real-world case:
A supermarket in Cali (2024) was fined R$800,000 and ordered to remove a 32㎡ screen due to missing certification.
Sostron’s one-stop compliance service has helped 17 clients pass customs inspections, reducing certification cost by an average of 30%.

Engineer’s Guide: Pixel Pitch, Control Systems & Installation Tips
Pixel Pitch Formula
Optimal pixel pitch (mm) = Viewing distance (m) × 0.3 / 1000
Example: 20-meter viewing distance → P6 (20×0.3/1000 = 0.006m)
NovaStar Control System Tips
-
Refresh rate: Enable “Auto Dynamic Refresh” → adjusts between 1920–3840Hz
-
Color calibration: Use TS600 and lock color temperature at 6500K (Colombian ad industry standard)
-
Remote management: Enable cloud monitoring; set temperature alarm at 60°C
Installation Recommendations
-
Outdoor screen tilt: 3–5° to prevent water accumulation
-
Power wiring must meet NTC2057, wire gauge ≥ 2.5mm²
-
Coastal areas require cathodic protection to prevent steel corrosion
