Description: LIGHT EMITTING DIODE BLUE LIGHT: The LED light curing machine adopts light emitting diode blue light, which does not generate heat during operation, does not need fan cooling, and has no troubles of noise and vibration. 3 MODES: curing working light mode has three modes: strong light mode, pulse mode and gradual bright mode. LARGE CAPACITY BATTERY: 2200mAh large capacity lithium ion battery, which can last about 130-200 times (4-8 hours) after being fully charged. WIRELESS: Wireless operation is more convenient, 20S no button operation automatically shuts down, saving power. With a charging base, the handle can be placed horizontally or vertically to protect the light guide rod. LOW BATTERY REMINDER: When the battery is low, it will alarm and the light will flash. Specification: Material: ABS Plastic Curing Time and Depth: 5S/3mm Blue Light Wavelength: 420-480nm Blue Light Intensity: 1200-2000mw/cm² Battery Capacity: 3.7V 2200mAh Battery Input Voltage: 110-240V 50-60Hz Applicable Temperature/humidity: 5°C-50°C/
