"The product’s success comes from firsthand experience. I sat in the same chair as our customers. I felt the pain points they felt daily. I thought, ‘How has no one made a light for service providers?’

I knew I had to be the one to bring this light to market. It will help so many. We redefined lighting across industries and are now adding markets across the world."
