LED Filament Bulbs: A Blend of Vintage and Modern

LED filament bulbs combine the warm aesthetics of vintage Edison lamps with modern LED efficacy — a combination that hospitality designers increasingly specify for restaurant and hotel interiors. Kingseng’s approach to filament technology focuses on commercial-grade reliability without sacrificing the vintage look.

How Kingseng Filament Technology Works

Our filament bulbs use COB-on-glass technology: multiple tiny LED chips arranged linearly on a transparent sapphire substrate, then coated with a phosphor blend that delivers CRI > 90. This produces true 360-degree omnidirectional light — unlike standard SMD bulbs that have a dead zone at the base.

Commercial Specifications

— Efficacy: 90–110 lm/W (vs. 10–15 lm/W for genuine vintage Edison bulbs)

— Beam: Full 360° omnidirectional

— CRI: Ra > 90

— Lifetime: 25,000 hours L70

— Dimmable: 0–10V and TRIAC compatible

Where to Specify Filament Bulbs

Pair them with our KS-PL pendant series (KS-PL-001 to KS-PL-013) over restaurant tables for an exposed-bulb industrial look, or use with KS-WS wall sconces (KS-WS-001 to KS-WS-009) in hotel lounge areas. The 2700K warm CCT creates the nostalgic ambience patrons expect in gastropubs and boutique bars, while the LED internals keep energy costs in check for the operator.
