I got lumadent because I liked that Dr. Ton, the creator, frequented forums like SDN and Dental Town and communicated with his potential customers. He actually saw another member of DT make his own light with one of those head lamps you can get from hardware/outdoors stores. He developed a battery pack for it that kept the light at full intensity until the batteries completely died (as opposed to most flashlights that get dimmer as the batteries die). So many people bought them that he developed a light, and eventually his own loupes. The LumaDent rep was also very helpful and humble. Across the hall, the CEO/owner of Ultralight was there openly talking trash about LumaDent's products. That totally turned me off to the company. I have no doubt that they have decent, if not great, lights. But be professional.
