Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ191010001-00A GENERAL INFORMATION Product Description for Equipment under Test (EUT) Product# Grilluminate tri-mount light Model# CGWM-074 Voltage Range DC 1.5V*6 from battery Highest operating frequency 32768Hz Date of Test 2019/10/15 Sample serial number 191010001 (Assigned by Shenzhen BACL) Received date 2019/10/10 Sample/EUT Status Good Condition Objective This test report is prepared on behalf of Ningbo Shuanghe Hongsheng Electronic Technology Co.,Ltd in accordance with Part 2-Subpart J, Part 15-Subparts A, B of the Federal Communication Commissions rules. The objective of the manufacturer is to determine the compliance of the EUT with FCC Part 15 B. Related Submittal(s)/Grant(s) No related submittal(s). Test Methodology All measurements contained in this report were conducted with ANSI C63.4-2014, American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the range of 9 kHz to 40 GHz. All emissions measurement was performed at Bay Area Compliance Laboratories Corp. (Shenzhen). The radiated testing was performed at an antenna-to-EUT distance of 3 meters.

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ191010001-00A Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, antenna factor calibration, antenna directivity, antenna factor variation with height, antenna phase center variation, antenna factor frequency interpolation, measurement distance variation, site imperfections, mismatch (average), and system repeatability. Based on CISPR 16-4-2:2011, the expended combined standard uncertainty of test at Bay Area Compliance Laboratories Corp. (Shenzhen) is shown as below. And the uncertainty will be taken into consideration for the test data recorded in the report Parameter uncertainty Emissions, Below 1GHz ±4.75dB radiated Note: The extended uncertainty given in this report is obtained by combining the standard uncertainty times the coverage factor K with the 95% confidence interval. Otherwise required by the applicant or Product Regulations, Decision Rule in this report did not consider the uncertainty. Test Facility The Test site used by Bay Area Compliance Laboratories Corp. (Shenzhen) to collect test data is located on the 6/F., West Wing, Third Phase of Wanli Industrial Building, Shihua Road, Futian Free Trade Zone, Shenzhen, Guangdong, China. The test site has been approved by the FCC under the KDB 974614 D01 and is listed in the FCC Public Access Link (PAL) database, FCC Registration No.: 342867, the FCC Designation No.: CN1221. The test site has been registered with ISED Canada under ISED Canada Registration Number 3062B. FCC Part 15B, Class B Page 4 of 10

The specification used was the FCC Part 15.109 Class B limits. The external /O cables were draped along the test table and formed a bundle 30 to 40 em long in the middle. The spacing between the peripherals was 10 cm. EMI Test Receiver Setup The system was investigated from 30 MHz to 1 GHz During the radiated emission test, the EM test receiver was set with the following configurations: Frequency Range RBw Video BA P BW Measurement 30 MHz — 1000 MHz 100 kHz 300 kHz 120 kHz QP Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. All data was recorded in the Quasi—peak detector mode from 30 MHz to 1 GHz. FCC Part 15B, Class B Page 8 of 10

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ191010001-00A Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the Amplifier Gain from the Meter Reading. The basic equation is as follows: Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss - Amplifier Gain The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of 7 dB means the emission is 7 dB below the limit. The equation for margin calculation is as follows: Margin = Limit – Corrected Amplitude Test Results Summary According to the EUT complied with the FCC §15.109 Class B Test Data Environmental Conditions Temperature: 25 ℃ Relative Humidity: 52 % ATM Pressure: 101.0 kPa The testing was performed by Steve Lan on 2019-10-15.
