Xlite LED Curing Light The Flight LED XLite Curing Light is a high power 1,700 mw/cm2 curing light with the ability to cure most composites within the wavelength of 385-515nm. The 5w LED curing light uses an easily replaceable Lithium Ion battery(3.7VDC) with a full charge that can last up to 30 minutes of continuous use. The unique small head design of the curing light eliminates the need for fiber optic rods that can break and damage over time. The LED is focused directly on the curing light using a glass lens that collimates the LED light. The small 90 Degree head also enables easy access to the posterior of the mouth unlike other curing lights where special fiber optic rods are required to access the posterior of the mouth. The 330 degree swivel head also allows flexibility for the user to access all parts of the mouth.
