The maximum light intensity of the proposed device is higher than the predicate device which can achieve higher efficiency for irradiating polymer-based restorative materials, but it is still lower than a reference device K221194 (the claimed maximum light intensity is Max. $3200\mathrm{mW/cm^2}$).

The light output safety and performance test was conducted according to ISO 10650, IEC 62471, IEC 60601-1 and FDA guidance performance testing requirements.

The testing results show that these difference do not affect the safety and effectiveness.

Note 3 The proposed device is charged by the contact charging method as same as the primary predicate device. As a power source for the charger, the AC/DC adapter provided by the manufacturer is used. The input specifications of the adapter (100-240VAC, 50-60Hz) are the same, but the outputs differ from each other at $5\mathrm{V} \times 2\mathrm{A}$ and $5\mathrm{V} \times 1.5\mathrm{A}$ respectively. These difference do not affect safety and effectiveness.

Note 4 In order to block the blue light radiation outside the application part to protect the eyes of the operator and patient from blue light hazard, the proposed device provides two accessories: Eyes protector and Eye protector unit, and the predicate device only has Protection glasses which is same with Eyes protector. Eye protector unit provides an additional solution to protect the eyes of dentists and patients from hurting. This difference does not affect the safety and effectiveness.

Note 5 The proposed device and the secondary predicate device have dual peak wavelength. The peak wavelength of the proposed device is described as given values while the peak wavelength of reference device as a range. The values are similar. This difference does not raise issues of substantial equivalence.

Note 6 According to the requirements of US national differences, the proposed device has tested by ANSI AAMI ES60601-1 and ANSI AAMI ES60601-1-2.

Different but does not adversely impact safety and effectiveness of proposed device.

## Discussing:

The new device LED Curing Lights (Model: DB686 HALO) is substantial equivalence as the primary predicate device K220826, the secondary predicate device K220471 and the reference devices (K221194, K221152). The differences was in model and some minor parameters, it's because of they are different in design requirements between different devices, which not affect the safety performance of the device, and the new device passed Safety testing, so these differences will not cause any safety and effectiveness issues. Considering the same intended use/indications for use, principles of operation, and product performance etc., they are substantial equivalence.

## 7. Non-clinical Data

All nonclinical testing performed on new devices is to demonstrate the substantial equivalence to the predicate devices. Tests setup and execution are performed in accordance with applicable standards. Results of the testing demonstrate the compliance to the standards and matching the performance of new devices to the predicate devices.
