Irradiance vs power, beam size, even the tools used to measure light outputs all play major roles in how a curing light will function. To find true quality and efficiency in a light, a user must be able to wade through the waves of false and misleading claims often made in the world of dental curing light advertising—Ultradent’s Sr. VP of Research & Development, Neil Jessop, delves into these topics and more in this edition of Dentistry Decoded: Insights from R&D.

While there is no doubt irradiance adds value, it does not tell the full story of how well a light will cure various materials. Irradiance tests typically only show the irradiance of a very small portion of the light. Measuring the power distributed over the entire beam tells a more comprehensive story of its curing capabilities.
