The ST64 is one of the most recognizable shapes in decorative lighting — a classic teardrop Edison silhouette used in pendants, exposed-bulb fixtures, restaurants, and architectural installations. At Luxray, we manufacture ST64 LED filament bulbs across the full specification range, with options refined over years of experience serving clients across diverse markets.
Different projects call for different bulbs. A deep-amber 2200K version suits an intimate bar or dining room; a cleaner, higher-output bulb suits a hotel lobby or larger fitting; a specific base type matches a particular fixture. Whatever the requirement, we help you find the right specification — and where a project needs something beyond our standard range, we build it to order, including custom color temperature, high-CRI options, specific luminous efficacy targets, and OEM production for branded ranges.
Every specification below is proven in real installations and produced with consistent quality, batch after batch — so whether you are sourcing for stock, specifying for a project, or developing a branded line, you can rely on what you order.

Batch consistency
Color temperature and brightness held consistent across production 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
