Solar warning lights have been successfully deployed at a large construction site in Kenya. The successful implementation of this project not only marks the further expansion of YFFY’s aviation obstruction lights in the East African market but also provides strong technical support for construction safety in the region.
Project Background: Aviation Warning Challenges in High-Altitude Operations
On Kenyan construction sites, with the rise of high-rise buildings and the widespread use of large lifting equipment, aviation obstruction warning lights have become an indispensable part of construction safety management.
Traditional wired aviation obstruction light systems face several pain points in practical applications:
- Complex wiring, requiring coordination of temporary on-site power supply;
- High maintenance costs, limited by grid stability;
- Difficulty in ensuring continuous operation in remote or unstable power areas.
Against this backdrop, how to achieve low-cost, easy-to-deploy, and sustainable aviation warning systems has become a pressing issue for construction companies.
Solution: YFFY-LS-E Solar Warning Lights
1. Completely Off-Grid, Flexible Installation
- Low-intensity obstruction light with built-in high-efficiency solar panel and lithium iron phosphate battery;
- No wiring or external power supply required, suitable for various temporary construction sites;
- Weighs only 3.5KG, easy to transport and install at heights;
- Secured with M8 bolts, bottom mounting hole spacing Φ234mm, adaptable to various structures.
2. Intelligent Light Control, Automatic Operation
- Solar LED warning light equipped with a high-sensitivity light sensor;
- Automatic charging during the day and automatic activation at night, enabling unattended operation;
- Effectively reduces the frequency of manual inspection and maintenance.
3. Long Battery Life, Adaptable to Variable Climates
- LED solar warning lights with built-in 6.4V / 6Ah high-capacity battery;
- Equipped with an intelligent power management system, it can operate for more than 15 days in continuous cloudy or rainy weather;
- Suitable for regions with unstable light conditions, such as Kenya.
4. Compliant with International Standards, Safe and Reliable
- Obstacle warning lights comply with FAA L810 and ICAO Type B standards;
- For example, the YFFY-LS-E solar-powered aviation light has a luminous intensity of 32.5 cd and supports both constant and flashing modes;
- Horizontal beam angle of 360°, vertical divergence angle >3°;
- IP65 protection rating, suitable for environments from -40℃ to 70℃;
- Withstands wind loads of up to 80 m/s, suitable for high-dynamic scenarios such as tower cranes.
Installation Practice: Application Solutions Adapted to Different Construction Site Structures
In this Kenya project, YFFY developed differentiated installation solutions based on different building structures to ensure maximum warning effectiveness.
✅ Installation Standards for Buildings Below 45 Meters
YFFY’s LED low-intensity obstruction lights are suitable for buildings under construction or temporary facilities below 45 meters in height:
- Location Selection: Install the high-altitude warning lights at the highest point of the building or on protruding edges;
- Lighting Strategy: Install a single layer of solar warning lights at the top; for larger areas, ensure complete coverage without blind spots;
- Fixing Method: Secure to walls, roofs, or brackets using bottom mounting holes;
- Precautions: Ensure the solar panel faces the sun to avoid shading.
✅ Installation Solution for Construction Cranes (Tower Cranes)
For dynamic, high-altitude operation scenarios:
- Highest Point Installation: Fix the medium-intensity obstruction lights to the top of the tower cap or the end of the counterweight boom;
- Vibration-resistant Design: Use anti-loosening pads and high-strength bolts to ensure stable operation;
- Follow-up Characteristics: The aircraft warning lights rotates with the boom, always achieving 360° red light coverage, effectively warning aircraft from all directions;
- Independent Power Supply: Solar power avoids the contact problems or wiring tangles associated with slip ring power supplies.
This successful case study at a construction site in Kenya fully demonstrates the superior performance of our YFFY-LS-E solar warning lights in complex environments.
From buildings under 45 meters tall to towering cranes, we safeguard every construction worker with products that meet international standards and professional installation guidance.
In addition, we also offer medium-intensity lights and high-intensity aviation lights for use in construction, cranes, towers, chimneys, helipads, and other applications requiring obstruction warning lighting.
In the future, we will continue to dedicate ourselves to providing more efficient and intelligent aviation obstruction lighting solutions, making construction sites around the world safer and brighter.
