The tubular filament bulb is one of the most versatile shapes in decorative lighting, and Luxray has refined it over decades. Every tube carries the warm, vintage character of a traditional Edison lamp, now driven by modern LED for far lower energy use and a much longer life. As one of the earliest LED-filament developers in China, our team draws on 30-plus years spent mastering halogen, incandescent, energy-saving and SMD lighting before this.
What sets these tubes apart is measurable rather than cosmetic. Because the filament and gas-fill are engineered in-house, our tubulars hold their brightness far longer than typical filament bulbs — the low lumen depreciation, extended service life and build-to-spec flexibility that specifiers and OEM buyers actually test for. Hotels, interior designers and lighting brands across Europe and North America build them into their projects for exactly this reason.
Within the tubular family the range runs from slim T20(T6), T25(T8) and T30(T9) tubes — sized for pendants, wall fittings and signage — up to full-bodied T45(T14) tubulars and striking extra-long T28 tubes reaching 1250 mm for stairwells, atriums and feature runs. Glass comes in clear or amber; filaments in straight, parallel or spiral styles; and bases in E14/E12 and E27/E26 to drop straight into both European and North-American fittings.
Quality is proven, not claimed: each tube is validated in our own TÜV-approved lab and carries CE, ErP and RoHS for Europe plus ETL for North America. Alongside our stocked standard tubes, we build to order — bespoke colour temperatures, high-CRI variants, higher-efficiency versions, function-specific designs, and private-label or full OEM runs.

How We Build It
A decorative bulb is only as good as the details behind it. We control both how it performs and how it looks — from the engineering inside to the finish you see.
01 — GLASS
Glass, Selected and Cleaned by Hand
On a clear filament bulb, the glass has nowhere to hide — every streak, bubble, or speck shows once the light is on. That’s why every envelope is inspected piece by piece on arrival, then hand-cleaned before assembly. Envelopes that don’t meet our clarity standard are rejected, not reworked.
Incoming inspection on every envelope, not sample checks
Hand-cleaned before assembly for a flawless finish
Sub-standard glass rejected before it enters production
Inspection covers clarity, wall thickness, and neck dimensions.
02 — FILAMENT
Filaments Designed to Be Seen
Filaments Designed to Be Seen
On a decorative bulb, the filament is the design. We shape and position each filament for visual balance and a refined glow — and we fix the geometry per model, so filament angle and spacing stay identical from bulb to bulb. When a project installs fifty bulbs in one chandelier, they all look like one family.
Filament layout fixed per model — no visible variation across a batch
Soft, even glow without hot spots or glare
Custom filament shapes available for OEM projects
03 — GAS-FILL
Patented Gas-Fill Technology
Most decorative bulbs dim noticeably within the first year or two. Ours are built not to — the gas mixture sealed inside each bulb is engineered to slow lumen depreciation and protect the LED filament across its full working life.
Lumen maintenance above [90]% at [6,000] hours
Consistent brightness and color, batch after batch
Every production run verified by in-house aging tests
04 — COMPONENTS
Matched Components, Not Standard Parts
A dim-to-warm bulb and a high-CRI clear bulb shouldn’t run on the same driver — so they don’t. Filament and driver are specified per model, and the production process is tuned to each design, so every variant performs exactly as its spec sheet promises.
Driver matched to each model — flicker-free, smooth dimming where specified
Full traceability: every batch linked to its component lot
Spec sheets reflect tested values, not catalog claims
