This document is a request for confidentiality submitted to the Federal Communications Commission (FCC) by LEEDARSON LIGHTING CO., LTD. The request pertains to withholding certain attachments from public disclosure indefinitely, specifically the schematic diagram, block diagram, and theory of operation for their lighting device. The request is made in accordance with Sections 0.457 and 0.459 of the Commission's rules (47 CFR §§ 0.457, 0.459). LEEDARSON argues that these documents contain detailed system and equipment descriptions that are considered proprietary information. Public disclosure of this information could be harmful to the company and provide competitors with an unfair advantage in the market. The company understands that measurement test reports, FCC ID label format, and correspondent information will be available for public review once the grant of equipment authorization is issued. The letter is signed by Vick Zhang, a safety engineer at LEEDARSON LIGHTING CO., LTD.
