Intensity Meter/ Light Meter

Intensity Meter/ Light Meter is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. A light meter can read the ambient light in a scene, or the direct light from a light source. There has been a trend in moving away from the traditional halogen and xenon plasma arc curing lights to smaller. More efficient, portable LED curing sources. This trend is probably due to the rugged nature of the LED. Air cool the tooth and the restoration during each light curing cycle. The powers measured from radiometers are the irradiance level at the tip of a curing light.
