Solar-powered red LED warning beacon – IP65, with spring clamp, up to 9 days of operation
Solar-powered LED warning beacon is intended for temporary or permanent marking of hazardous areas, structures, equipment and obstacles. The bright flashing red signal helps attract attention in high-voltage line areas, road maintenance zones, tower cranes, vessels, navigation channels and near other technical equipment.
The beacon has an integrated solar module and a rechargeable 3.7 V, 1000 mAh battery. During the day, the solar module charges the battery, and the stored energy is used to generate the red LED light signal. The specified flashing rate is approximately 75 flashes per minute.
The beacon is secured with a metal spring clamp that can be quickly attached to a suitable pipe, rod, profile or edge of a structure. The compact design does not require a separate electrical cable, making the product convenient for locations without a permanent power supply.
Autonomous power supply:
The integrated solar module charges the internal battery, so the beacon does not require a permanent wired power supply. Before first use, the protective film must be removed from the solar module.Important information about operating time:
The stated continuous operating time of up to 9 days applies to a fully charged battery. Actual operating time depends on sunlight intensity, charging duration, ambient temperature, battery condition and flashing mode.Warning device, not a certified navigation aid:
The supplied information does not specify certifications for aviation, marine navigation, road traffic or other specialised fields. Therefore, before use in regulated safety systems, verify that the product complies with the requirements of the specific project and applicable legislation.Light source

IP65Dimensions
170 × 160 × 90 mmBright red LED warning signal
The beacon uses a red LED light source that produces a clearly visible flashing signal. Red is widely used to indicate hazards, obstacles or restricted-access areas, so the beacon can help visually identify technical structures and hazardous workplaces.
The light signal may be visible from a distance greater than 500 m. Actual visibility depends on ambient lighting, weather conditions, viewing angle, installation height and possible obstructions.
Flashing rate of 75 times per minute
The beacon flashes approximately 75 times per minute. A periodically switching light attracts attention more effectively than weak continuous illumination and also helps conserve battery energy.
Integrated solar module
A solar module installed on top of the beacon converts solar energy into electrical energy during the day and charges the internal battery. Autonomous operation eliminates the need to route an additional power cable or install a separate power source nearby.
For effective charging, the solar module must face open sky and must not be covered by structures, leaves, dust or other objects. Prolonged shade can significantly reduce operating time.
Before first use:
Remove the transport protective film from the surface of the solar module. Leaving the film in place reduces light transmission and may prevent the battery from charging properly.3.7 V, 1000 mAh rechargeable battery
The beacon uses a rechargeable battery with a rated voltage of 3.7 V and a capacity of 1000 mAh . It stores the energy generated by the solar module and powers the LED light source during darkness or insufficient lighting.
The battery service life is stated as up to approximately 1000 charging cycles. The actual number of cycles depends on discharge depth, temperature, charging conditions and the overall usage pattern.
Up to 9 days of operation when fully charged
A fully charged beacon can operate for up to 9 days. This allows the warning signal to remain active for several days during cloudy weather or reduced solar radiation.
For long-term autonomous operation, the solar module must regularly receive direct sunlight or sufficiently intense diffused daylight. Installation under a roof, indoors or in permanent shade may not provide adequate charging.
Spring mounting clamp
The beacon is secured with a metal spring clamp. The upper part of the clamp can be pulled open, placed over a suitable structure, and released so that the spring presses the mounting element firmly in place.
This solution allows installation without welding or complex drilling. The beacon can be moved quickly to another location, making it suitable for temporary work, construction sites, road maintenance and mobile equipment.
The spring clamp is suitable for pipes approximately 20–50 mm in diameter.Mounting safety:
A spring clamp alone may be insufficient in locations exposed to strong vibration, impacts, high winds or moving equipment. In such cases, an additional safety cable or another secondary fastening method is recommended.Reinforced steel mounting structure
The bracket is made of reinforced steel. The thicker metal construction helps reduce the risk of deformation when the beacon is attached to a pipe, profile or other technical structure.
The steel surface has an electrostatic powder coating to improve resistance to corrosion and environmental effects. The coating helps protect the metal from moisture, but damaged, scratched or chipped areas should be inspected periodically.
IP65 protection against dust and water
IP65 protection rating means that the enclosure is protected against dust ingress and water jets from different directions. This allows outdoor use when the product is properly installed and undamaged.
IP65 does not mean the product can be submerged:
The beacon is not intended for continuous immersion in water. High-pressure washing, prolonged water accumulation around seals and mechanical damage to the housing should also be avoided.Technical specifications
