Compared to standard halogen bulbs, LED units use semiconductors, usually gallium nitride, to produce a more narrow spectral range that is closer to the absorption spectrum of the camphorquinone (450 to 490 nm) that initiates resin polymerization. Due to the combination of this more specific spectral range and the LED's superior energy conversion rate when compared to halogen lamps, the Elipar™ FreeLight is purported to generate sufficient intensity for polymerization using rechargeable Nickel-Metal-Hydride batteries rather than line voltage. Because it does not have a bulky power unit and cords, 3M ESPE claims that the light is portable, lightweight, and very convenient to use. A new, fully-charged battery is reported to typically provide 45 minutes of exposure time and requires two hours to recharge when completely discharged. The timer controls and on/off control are located on the handpiece. Four curing times can be selected (10, 20, 30, or 40 seconds) and audible beeps alert the user to the length of exposure (i.e., one beep at 10 seconds, 2 beeps at 20 seconds, etc.) An intensity tester is built-in to the charging stand and indicates the relative intensity of the light's output (i.e., 20%, 40%, 60%, 80%, or 100%). The Elipar™ FreeLight handpiece is 11.2 inches long X 1.2 inches in diameter and weighs 11.3 ounces. The system has been rarely used and is in perfect working condition.  Place a Bid!
