Ligman Lighting has reimagined the standard bird spike to develop a more efficient and aesthetically pleasing bird deterrent for outdoor luminaires. The decorative bird deterrents are easily attached to the surface of Ligman’s outdoor luminaires. The design utilizes a single unit that is secured to the surface of the luminaire so that the shape and the style of the luminaire is not visually compromised. The deterrents can be easily retrofitted to existing applications, or supplied with new orders. These patent pending bird deterrents are available for the vast majority of pole top and streetlight ranges produced by Ligman Lighting.
