Lights Clesta dental lights continue as one of the most popular and innovative lights in the dental marketplace. Lights feature a 5000°K color temperature range setting that approximates mid-day sunlight. The Clesta name is derived from “Clean Station”. This description refers to the touchless ON/OFF sensor feature which minimizes potential cross-contamination that can occur as a result of contact with the light between procedures. Clesta dental lights are available in unit mounted curved post or straight post versions or as wall, ceiling, track and cabinet mounted versions.
