G4 bulbs are compact bi-pin LED capsules used wherever a small light source is needed. Most are 12V low-voltage, run from a transformer, with 220V versions also available for direct mains fittings. Luxray produces them from 2W upward, in warm white through daylight, dimmable and non-dimmable — direct replacements for G4 halogen capsules, with far lower energy use and a much longer life.
G4 LED capsules are widely built into cabinet and display lighting, under-shelf and mirror lights, desk lamps, chandeliers and decorative fixtures. The range covers retail and distribution as well as project and OEM requirements, in a full span of wattages and colour temperatures to match the fixture and the application.
Product development is handled in-house, backed by our own LED packaging facility — so performance can be pushed beyond off-the-shelf parts. Colour temperature, CRI, lumen output and wattage are tuned to each requirement, with consistent quality from sample to production. Custom samples are produced quickly, and small trial orders are accepted for validation before volume.

Manufactured, Not Just Supplied
30+ years’ expertise
Our team brings over 30 years of industry experience, focused on premium custom light sources since 2014.
Full certification
CE, RoHS, ETL, and ERP test reports issued by internationally recognized laboratories — SGS, TÜV, and Intertek.
In-house sampling
We develop and produce samples in-house, with one-to-three approval rounds for custom work.
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
