Device Story

Delight, Delight ortho, and B&Lite S are cordless, LED-based dental curing lights; used by dental professionals to polymerize light-cure resin-based composites, luting materials, and cements. Devices emit narrow-spectrum blue light (430-490nm) to activate CPQ molecules in dental monomers. Handheld, battery-operated design ensures portability. To prevent cross-contamination, devices are used with FDA-cleared disposable barrier sheaths (TIDIShield). Clinicians select specific operation modes (Standard, High/Fast, Soft Start, Pulse/Sequential, Ortho/Turbo) based on required light intensity and duration to achieve optimal polymerization. Output intensity ranges from 800 to 2,700 mW/cm² depending on the model and mode. Benefits include efficient, portable, and controlled light-curing for various dental restorative procedures.

Clinical Evidence

Bench testing only. Performance evaluated via optical power testing, spectral irradiance (wavelength spectrum), and depth of cure (composite hardness testing) in accordance with ANSI/ADA Specification No. 48:2004, ANSI/ADA Specification No. 48-2:2010, and FDA guidance for dental curing lights. Electrical safety and EMC testing performed per IEC 60601-1:2005+A1:2012 and IEC 60601-1-2:2007. All results conformed to standards.

Technological Characteristics

LED-based dental curing light; 10W LED source; 430-490nm wavelength (460nm peak). Powered by internal 3.7Vdc 2200mAh Li-ion battery; rechargeable via AC/DC adapter (100-240Vac). Handheld form factor. Patient contact via disposable barrier sheath. Compliance: IEC 60601-1, IEC 60601-1-2, ANSI/ADA Specification No. 48, ANSI/ADA Standard No. 48-2.

Indications for Use

Indicated for light curing polymerization of dental composites, luting materials, cements and other light cured materials in a dental clinical setting.

Regulatory Classification
