Everything You Need to Know About Incandescent Bulbs in 2025


Despite the rise of LED lighting, incandescent bulbs remain popular for their warm glow and affordability. Whether you're a homeowner or a business buyer, understanding their types, features, and sourcing options is crucial. This guide covers everything from selecting the right bulb to finding trustworthy suppliers.


How to Find Reliable Incandescent Bulbs from China in 2025


China remains a top manufacturing hub for incandescent bulbs, offering competitive pricing and bulk options. To ensure quality:

  • Verify supplier certifications (e.g., ISO, CE, RoHS)
  • Request samples before large orders
  • Check Alibaba reviews with at least 4.5-star ratings
  • Confirm OEM/ODM capabilities for custom designs

Top-rated manufacturers often provide energy-efficient halogen variants (15%-20% brighter than standard bulbs).


What Buyers Should Know Before Buying Incandescent Bulbs from China


Key considerations include:

  • Minimum Order Quantity (MOQ): Typically 500-1,000 units for wholesale
  • Shipping costs: Sea freight saves 60% vs. air for bulk orders
  • Voltage compatibility: Specify 110V or 220V versions
  • Lead time: Allow 15-30 days for production and delivery

Case Study: A US hotel chain saved 40% by sourcing dimmable incandescent bulbs directly from Guangdong factories.
