What is an LED Filament Bulb
An LED filament bulb combines the nostalgic look of an incandescent lamp with modern LED efficiency. Tiny LED chips are mounted on a slender, transparent filament and arranged to emit light in a full 360° glow — closely mimicking the warm, even light of a traditional Edison bulb while using a fraction of the energy.
Because the filaments are visible through clear or amber glass, the bulb doubles as a decorative element, making it a favourite for hospitality, retail and residential vintage styling.

Features of LED Filament Bulbs
Lower Energy Consumption
Up to 80–90% less energy than incandescent bulbs — a 6W filament bulb replaces a 60W incandescent at equal brightness.
Reduced Carbon Footprint
Higher efficacy means lower CO₂ per lumen, supporting green procurement for EU and North American buyers.
Extended Lifespan
Rated 15,000–25,000 hours, cutting replacement frequency and maintenance cost in commercial use.
No Hazardous Materials
Mercury-free and RoHS compliant, safer for disposal and fully aligned with WEEE requirements.
Parts of an LED Filament Bulb
Semiconductor filament emitting light when current passes through.
Aluminium body dissipates heat to protect the chip and extend life.
Converts AC to stable DC and protects against voltage fluctuation.
Clear/amber glass and phosphor coating shape the 360° warm glow.
Glass envelope and metal base (E26/E27/B22) for mounting.
How to Choose LED Filament Bulbs
400–600 lm suits accent or small rooms; 800+ lm for primary lighting in larger spaces.
Lower wattage = higher efficiency. Choose by lumens, not watts, to match the look you want.
2700K warm for living rooms/bedrooms; 4000K neutral for kitchens and offices.
Select dimmable SKUs and pair with LED-rated dimmers to avoid flicker.
E26/E27 for most fixtures; B22 bayonet for UK/AU markets — confirm by region.
A/Globe/Candle/ST/T — pick by fixture style and decorative intent.
Application Scenarios
Filament bulbs are chosen wherever warm ambience and visible-light aesthetics matter.
Chandeliers & Pendants
Exposed bulbs in clusters create a signature vintage focal point.
Cafés, Restaurants & Bars
Warm 2700K glow builds a welcoming, photogenic atmosphere.
Hotels & Hospitality
Durable, low-maintenance retrofit for guest rooms and lobbies.
Retail Display
High-CRI light renders merchandise colours accurately.
Home Vintage Decor
Living rooms and bedrooms gain cosy, heritage-style lighting.
Events & Holiday
Special-shaped bulbs for themed and seasonal decoration.
Manufacturing Process
Glass Cleaning & Drying — glass is cleaned, dried and stored on grid plates to avoid abrasion.
Filament Spot Welding — LED filaments welded to glass mounts under constant temperature/humidity, then light-tested before sealing.
Seal, Exhaust & Gas Filling — bulbs sealed with inert gas cooling system.
Driver Assembling & Socket Fixing — driver attached and insulated; base fixed and heat-cured.
Light Test & Aging — each bulb lit up and aged ≥ 6 hours to catch defects early.
