Fail-safe street lights in the event of a power failure

Informations about:	Hybrid street lights for road lighting

Public lighting fails in the event of a power outage caused by grid disruption, excavation work, severe weather, storms, snow, earthquakes or other disasters. Houses, streets and squares remain dark. Hardly anyone is prepared for such an event, as we learned during the prolonged power outage in Berlin in 2026. Uncertainty arises, the risk of accidents increases and the risk of crime rises.

GEO-Technik manufactures so-called hybrid street lights that operate with maximum reliability. They are powered by the normal mains supply on the one hand, and by a long-life battery and a particularly effective solar module on the other. The PV module also measures brightness and controls automatic switch-on at night. A clever control system automatically selects the optimum operating mode, dims the light as required and has additional safety functions.

Depending on the desired self-sufficient operating time, the lights can be produced with different battery capacities and PV module sizes.
Special functions are also available, such as ...

Motion detectors for lighting as required as soon as a person or vehicle enters the detection radius.
Precise time control for bus stops, jetties, ferries, etc. for lighting according to timetable.
Lighting on demand via push buttons at crossings, bus stops, sports fields or remotely controlled at fire brigade exits.

The dimensions of the solar module and batteries depend on the power consumption of the luminaire and the number of hours of sunshine per day, which vary depending on the geographical location.
The luminaire must also be prepared for dark winters or several rainy days when there is no sunlight available to charge the battery,
so that it can continue to provide self-sufficient and reliable lighting.

The lamp unit, known as the light head, can be designed as an LED light, sodium vapour lamp, HQI lamp or fluorescent lamp.

The service life of well-made solar lights is 15 to 20 years, although some components, such as the batteries, will need to be serviced or replaced during this time.

There are various types of hybrid and solar lights for public lighting:
	Hybrid solar street lights Fail-safe solar lights with emergency lighting. Available as complete street lights or as conversion kits for existing poles. Lighting is provided along the entire length of the road.
	Solar street lights High-performance solar lights. Sturdy, functional design. Storm-proof. Lighting is provided along the entire length of the road.
	Solar cycle path lights Solar lighting with lower power and lower height The lighting is provided along the cycle path, but also slightly to the side.
	Solar Park Lanterns Particularly decorative mast lights. The light is emitted in all directions, in a circular pattern, to illuminate the surrounding area as well. Examples of use: parks, gardens, marinas
	Solar lights with motion detectors The light only switches on when required, or when a person moves within range. The light is usually concentrated by one or two spotlights. Areas of application: car parks, private roads, driveways, animal stables, motels, guesthouses, holiday homes ...
	Bus stop lighting with solar power and LEDs Increased safety at bus stops and shelters. Legislators require local authorities to provide night-time lighting at bus stops to reduce potential hazards and the risk of accidents. Solar lighting offers a simple and inexpensive option for retrofitting. Even bus shelters without a connection to the mains power supply can be safely illuminated. ...
