Sass Lighting
High-performance bulbs engineered for durability and efficiency.
The global lighting market has undergone a seismic shift from traditional incandescent and fluorescent technologies to high-efficiency LED solutions. At the heart of this revolution is the E27 LED Bulb—the universal standard for screw-base lighting. Today, the E27 bulb is not just a household item; it is a critical component in commercial and industrial infrastructures worldwide.
Current industrial data suggests that the demand for E27 LED bulbs continues to grow at a CAGR of over 8% as emerging markets in Southeast Asia, Africa, and Latin America accelerate their urbanization. In developed regions like Europe and North America, the focus has shifted toward high-CRI (Color Rendering Index) bulbs and energy-saving compliance (such as the EU's ERP regulations). As a leading E27 LED bulb manufacturer, we analyze these global shifts to provide products that meet both the price sensitivity of developing markets and the stringent quality standards of the West.
E27 bulbs are no longer "dumb" devices. The integration of Zigbee, Matter, and Wi-Fi protocols allows for remote dimming, color shifting, and automated scheduling via smartphone apps.
Modern factories are producing E27 bulbs that mimic natural daylight cycles, improving productivity in offices and promoting better sleep cycles in residential settings.
To reduce carbon footprints and import duties, many global enterprises are sourcing SKD (Semi-Knocked Down) or CKD (Completely Knocked Down) parts for local assembly.
Jiangsu Sass Lighting Technology Co., Ltd. is China Solar Bollard Light Outdoor manufacturers and Modern Solar Bollard Lamp suppliers. Specializes in the research, development, production and sales of LED lighting products, providing professional indoor lighting solutions. Guided by the principles of Green, Energy-Saving, Eco-Friendly and Technology, Guangji Lighting uses advanced equipment and a professional team to develop stable and distinctive LED products. Looking ahead, we are committed to the vision of "Enjoying an Energy-Saving Future."

Our experienced R&D team works closely with you to bring your ideas to life. Whether you provide blueprints or samples, we develop products that match your specifications with precision.
As a direct manufacturer with our own workshop and warehouse, we offer factory-direct pricing while maintaining consistent product quality across all E27 LED bulb series.
We operate advanced production lines and a strict QC system. Our ISO 9001 certification and CE/ERP approvals ensure we meet the highest international standards.
For global enterprises, sourcing from a dedicated E27 LED bulb factory in China offers unparalleled advantages. The primary benefit is the Supply Chain Maturity. From the aluminum-clad PBT housing to the high-efficiency SMD chips and IC drivers, every component is sourced within a small geographical radius, drastically reducing lead times and costs.
Furthermore, China's manufacturing sector has moved from "Mass Production" to "Intelligent Manufacturing." Our facility incorporates automated assembly lines that ensure every E27 bulb has a consistent lumen output and color temperature. This precision is vital for B2B buyers who manage large-scale lighting projects in hospitality or retail, where consistency is non-negotiable.
We also specialize in OEM/ODM services, with over 13 years of export experience to Europe, the Americas, and the Asia-Pacific. We understand the nuances of local regulations—whether it’s the UL requirements for the US or the SASO standards for Saudi Arabia.
By choosing a factory-direct partnership, you bypass the middleman, ensuring that your technical requirements are communicated directly to the engineers who design the product. This leads to fewer errors, faster prototyping, and a more robust after-sales support system.
From warm 2700K filament bulbs for cozy living rooms to 6500K daylight bulbs for kitchens and home offices, our E27 range covers every domestic need.
High-wattage T-bulbs (T80-T140) are perfect for retail shops, supermarkets, and showrooms where bright, clear illumination is essential for sales.
Our motion sensor bulbs and emergency rechargeable units are designed for stairwells, warehouses, and areas where safety and reliability are paramount.
