Repel pigeons and other birds with this pulsing strobe
One million candlepower bulb sends out intense white, red and blue light at 75 flashes per minute. The unit creates light pulses and shadows that are intolerable and disorienting to birds. When installed at heights where birds normally roost, the light is barely noticeable by people on the ground. For use in warehouses, airplane hangars, packing sheds or any large, dimly lit area where birds create a nuisance. Covers up to 10,000 sq. ft. USA made.
