bulb lamp Sourcing Overview

Certification Compliance Risk Overlooking the importance of certifications like CE, RoHS, UL, and TUV often leads to regulatory hurdles and product recalls; ensure your supplier provides authentic documentation to avoid costly disruptions.

Specify Power and Base Compatibility Insist on clear specifications for power ratings between 1 W and 15 W and confirm the lamp holder base type (E27, B22, T5, or T8) matches your fixture requirements to prevent installation issues.

Material Selection Insight Experienced buyers typically prioritize aluminum alloy or COB LED materials for better heat dissipation and durability, whereas plastic or glass options may be more cost-effective but less robust.

Origin City and Cost Trade-offs The choice between manufacturing hubs like Guangzhou, Shenzhen, or Taoyuan directly affects lead times and pricing; balancing these factors can optimize your total procurement cost and supply reliability.
