U-40 Ultracapacitor Technology
Revolutionary U-40 Ultracapacitor Technology re-energizes to full power in under 40 seconds. Kerr Demi Ultra is the first and only curing light powered by state-of-the-art ultracapacitor technology. Although ultracapacitors are similar in size and shape to traditional batteries, they work much differently—re-energizing in a matter of seconds, and maintaining their energy capacity year after year.
In practical terms, the U-40 Ultracapacitor-powered Demi Ultra is never more than 40 seconds away from being able to deliver 25 ten-second cures. In your practice, the Demi Ultra delivers convenience, efficiency, and reliability—like nothing you’ve experienced before.

Proprietary C.U.R.E.™ Technology (Curing Uniformity and Reduced Energy) provides uniform depth of cure with industry-leading low temperatures. Enhanced collimation delivers more predictable curing power that is less sensitive to the positioning of the tip, while the more uniform beam generates a more consistent depth of cure.
Easy Suite feature set provides simple and intuitive operation and maintenance for seamless integration into your practice.
