Guide
While colored plastic-shell bulbs are favored for their durability and shatter-resistant qualities, colored glass bulbs remain highly popular. Coated with paint, glass bulbs offer vivid, vibrant colors and diverse designs that cater to high-end customers’ aesthetic preferences. However, few factories in the industry can meet environmental regulations while providing professional color-customization services.
Challenges faced by some factories include:
- Using non-environmentally friendly coating materials, violating environmental laws, and exposing customers to regulatory risks.
- Outsourcing coating processes, increasing costs for customers and delaying delivery times.
As a vertically integrated OEM factory, Kaiyu provides certified eco-friendly coating services, ensuring customers receive high-quality, eco-compliant, and competitively priced colored bulbs.
