Light Cure Green Rainbow

Rainbow Curing Light LED is a dental device used to polymerize light-cured dental materials, such as composite resins and bonding agents. The “LED” designation indicates that it utilizes light-emitting diodes as its light source, offering advantages like energy efficiency, longer lifespan, and typically a narrower and more consistent wavelength spectrum compared to older halogen or plasma arc curing lights. 1 The “Rainbow” likely refers to its ability to emit light across a broader spectrum of wavelengths, potentially encompassing the optimal ranges for curing various types of photoinitiators found in different dental materials. This broader spectrum can contribute to a more thorough and complete polymerization of the resin, leading to improved strength and longevity of the restoration. These curing lights are typically handheld, cordless or corded, and feature timers to ensure the material is exposed to the correct amount of light energy for proper curing.
