SunPOWR L-864/865
Dual Beacon

SunPOWR solar powered obstruction lights from P&R Technologies combine our long-life LED lights and beacons with state-of-the-art solar technology to meet FAA and ICAO standards in locations where grid power is not available or impractical. Savings in energy, relamping, and maintenance put LED solar lighting costs at under 10% of incandescent solar lighting. Choose from single or dual RTO lights and L-864 or L-864/865 beacons to fit your application. The size of solar panel is determined by the factory and based on where it will be installed.

The FAA advises that steady red obstruction lights be used on towers and communication obstructions from 50–2,200 ft. in height, which can pose a danger to small planes and helicopters at night. Steady red obstruction lights are advised up to 150 ft. in height, medium intensity flashing red or white lights up to 350 ft. high, and several levels of lights up to 1750 ft. See the FAA Advisory.

SunPOWR solar powered obstruction lights meet FAA and ICAO standards for obstruction lighting in locations where grid power is not available or impractical. These systems are sized for the type of light needed and sun exposure where the light will be installed.

SunPOWR Slashes Costs

Our SunPOWR solar powered obstruction lights cost less than 10% as much as incandescent solar systems, because:

  1. These solar powered obstruction lights are FAA approved LEDs (Light Emitting Diodes). LED lights use 5% of the power of incandescent lights and therefore require much less solar power equipment, fewer batteries, smaller solar panels, and less support structures.
  2. The LED lights have a 15 year life expectancy and are warranted for 5 years. Some utilities change as many as 300 incandescent light bulbs every year on obstruction lights, bringing significant costs in time, equipment, and manpower.
  3. Much less maintenance is required. The solar powered obstruction lights system has no working parts. Sealed, maintenance-free Gel Cell batteries are used. A wireless remote monitoring system can be added.

Solar Panel Selection

The size of the solar panel required depends on type of lights and the area of the world where the panel is to be installed. The panel will have to be twice as large in Seattle as it would be in Arizona. The number of sun hours available will determine the size of the panel required to produce enough power to operate the solar powered obstruction lights. The size will be calculated at the factory.

Meets FAA/ICAO Intensity Standards

The RTO Series SunPOWR system uses a steady red LED light. The L-864 SunPOWR system uses a flashing red LED light. And the L-864/865 SunPOWR system uses both flashing red and flashing white LED lights. The FAA specifies 32.5 candela intensity for towers up to 150 feet and 2,000 candela intensity flashing beacons on taller structures. See the FAA Advisory.
