LED light curing machine uses blue-light emitting diodes with a wavelength of 420–480 nm to cure dental resin. It features three curing modes: strong light, flashing light, and gradual light. The LED light source has a long lifespan, reducing maintenance costs. It operates without generating heat, eliminating the need for a cooling fan and ensuring quiet, vibration-free performance. Equipped with a high-capacity 2200 mAh lithium-ion battery (3.7 V), it provides approximately 130–200 curing cycles per full charge (4–8 hours charging time). An intelligent battery detection circuit alerts users with audible and visual signals when the battery is low. The lightweight, two-stage design delivers initial low-intensity irradiation followed by rapid curing to minimize resin shrinkage and reduce the risk of marginal gaps or cracks. Compatible with EU plug standard. Curing depth: up to 3 mm in 5 seconds. Light intensity: 1200–2000 mW/cm². Color: black. Material: plastic. Package includes: 1 x LED curing light unit. Note: Actual product color may vary slightly due to screen settings. Measurement tolerance: ±1–3 cm.
