LED Capsule Bulbs (G4 / G9)

G4 and G9 bi-pin LED capsules — compact halogen replacements in 12V and mains voltage, warm white to daylight, dimmable and non-dimmable, built to specification for lighting makers, distributors and OEM buyers.

Luxray supplies a complete range of G4 and G9 LED capsule bulbs, spanning the common wattages, colour temperatures, voltages and body styles, in both dimmable and non-dimmable versions. The range covers the needs of retail and distribution as well as hospitality and design projects, so a full capsule line can be sourced from a single partner.

Every model is developed with dedicated engineering support — optical, thermal and electronic design — and produced in an ISO 9001 certified facility. Rather than relabelling off-the-shelf stock, the light source is built to specification: colour temperature, CRI, efficacy and wattage tuned to each requirement. Custom samples are produced quickly, and small trial orders are accepted for spec validation before volume production.

This control over the light source keeps quality consistent from first sample through full production. From standard specifications to custom parameters, private-label and full OEM programmes, each order is built to requirement — for lighting manufacturers, distributors and project buyers across Europe, the UK and North America.
