Frequently Asked Questions (FAQ)

1. Can I get free LED samples from Hongcheng Optoelectronics?

Yes. Dongguan Hongcheng Optoelectronics Co., Ltd. supports sample testing — you can verify electro-optical parameters, dimensions and soldering compatibility before placing bulk orders. To request samples, call +86 139 2571 4318 (WeChat same number) or email sales@led-hc.com with the model and quantity you need.

2. What is the minimum order quantity (MOQ)?

The MOQ for DIP (through-hole) LEDs is 1K (1,000 pcs); for SMD LEDs the MOQ is 3-5K, shipped in tape-and-reel packaging. The MOQ for customized models (special wavelength, brightness or voltage binning) is confirmed per custom solution. Please contact sales for an accurate quotation and MOQ for your model.

3. What are the lead times for samples and mass production?

Sample lead time is typically 3-4 working days; in-stock samples are usually shipped within 2 working days. Mass production lead time is typically 10-15 working days, confirmed according to order quantity and production schedule — please contact sales for an accurate lead time.

4. Are the products RoHS certified?

Yes. All Hongcheng LED diodes are RoHS and CE certified, made with A-grade chips, 99.9% pure gold wire bonding and high-temperature resistant encapsulant — anti-sulfuration and low light decay, meeting the environmental and reliability requirements of home appliance, automotive and industrial equipment applications.

5. Can voltage, wavelength, brightness or color be customized?

Yes. We support binning and customization of brightness, wavelength, voltage and color, and provide OEM services. Our product range covers 0201-5730 SMD LEDs, addressable RGB LEDs with built-in IC, side-emitting LEDs, and 2mm-10mm DIP LEDs, packed in vacuum moisture-proof tape and reel, suitable for automated SMT mounting and reflow soldering.

6. How do I get the product datasheet?

Every model has an official PDF datasheet (electro-optical parameters, dimensions, pad design, tape packaging and reliability test data) — 259 datasheets in total, all free to download with no login required. Browse the datasheet center (https://www.hc-led168.com/datasheets) by series, or download directly from each product page.

7. Is Hongcheng Optoelectronics a factory or a trading company?

Hongcheng Optoelectronics is a member of Guangyu Group — a professional LED diode source manufacturer based in Dongguan, Guangdong, China, with 20+ years of LED packaging experience. Factory-direct sales; over 50% of raw materials are imported from South Korea, Japan and Taiwan, China. Quality and lead time are controlled directly by the factory.
