Since 2008, ZHL has overall shipped 2 million sets of Z-PLUS Series flood lights across the globe. Although the engineers spent a lot of energy to update and iterate the Z-PLUS to the third generation, the classic Z-PLUS series floodlights are still the clean and economical lighting solution of choice for the majority of engineers, builders and retailers. The reason for this is the stable performance of this luminaire, low light pollution, and low maintenance costs.
