LED light curing machine adopts the light-emitting diodes Blue-ray, it cancure the resin with the wavelength of 420-480nm, and be used to repairthe teeth in the department of stomatology; There are three solidification working light modes: strong light mode, flashing light mode, gradual light mode. The light-emitting diodeshas , which can greatly reduce the costs of maintenanceof the machine; Its does not produce any heat when running, so no needto cool it with fan, thus, it is free from the annoyance of noise andvibration of traditional machines; Thehigh capacity lithium ion batterycan last about130-200 times after being fully (4-8 hours). Intelligentbattery detection circuit function:when batteryis low, it alarm and the light flash. and two-stage design, first low-light irradiation, and then glare rapid curing. This can inhibit the excessive contraction of the resin , avoidcracks between cavities edge. Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on Battery (rechargeable): lithium ion battery Battery capacity: 2200mAh Battery voltage: 3.7V Curing time and depth: 5s/3mm Blue light wavelength: 420-480nm Blue light intensity: 1200-200mw/cm Colour:grey Material:plastic Voltage: AC110-240V Package Contents: 1 x Curing Light sets Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
