Demetron L.E.D. Radiometers

Dental Curing Lights

Recommended curing times with LED curing lights are based on the calibrated output of the light when brand new. Over time, several factors can reduce the output intensity of your curing light including: rough handling, material build-up on light guides, overheating, and bulb or battery degradation. A loss in output can affect the amount of time needed to efficiently cure material. We recommend periodic monitoring of light output. Most built-in radiometers offer vague percentages or "stop" and "go" lights for readings leaving you wondering what the true output really is.

Demetron® offers a lightweight, handheld solution for LED curing lights that precisely measures the radiant energy of each in milliwatts per centimeter squared (mW/cm2). The LED radiometer (blue) take away the guesswork of determining the accuracy of cure. And because our radiometers measure relevant light output where it counts - at the tip - its diagnostic capacity is reliable, so your cure intensity will be right - every time.

Does the output of your LED curing light degrade as the battery is drained?

Battery degradation must be monitored to ensure quality depth of cure. If you want a 10-second cure, you'll need to monitor frequently.

Does your unit have a fan?

If not, diodes will heat up over time and degrade output, causing loss of intensity.

Is your light guide autoclavable?

This feature is beneficial for hygiene, but residue and etched-in mineral deposits from repeated autoclavings can cause degradation.*

Is there composite on your light guide?

If so, you may not be getting the intensity of light needed for a complete cure.

Has your L.E.D. been dropped lately?

Accidental rough handling can seriously damage light intensity.
