LED, Vintage Filament, Halogen and Technical Bulbs: the Complete Range at Diffusione Luce

Diffusione Luce offers a wide selection of light bulbs and light sources for every domestic, commercial, and professional lighting need: LED bulbs, vintage filament bulbs, fluorescent neon tubes, metal halide discharge lamps, halogen bulbs, and related lamp holders. A range designed to cover every application, from replacing existing light sources to creating new lighting systems.

Available sockets and lamp holders

Our selection covers all the main bulb socket standards on the market:

• E27: the most widely used lamp holder, standard for most decorative and domestic lamps
• E14: the second most common type, typical of chandeliers, wall sconces, and compact table lamps
• GU10: 230V bayonet socket for recessed spotlights
• GU5.3: 12V bi-pin socket (requires a transformer), used in low-voltage recessed spotlights
• G9: 230V bi-pin socket, ideal for compact decorative lamps
• R7S: linear socket for tubular lamps, used in halogen floodlights and modern tubular LED lamps
• AR111: reflector with G53 socket, for professional spotlights with high luminous output

Bulbs for recessed spotlights: GU5.3 and GU10

Recessed spotlights generally use bulbs with a 50 mm diameter in two main versions: GU5.3 at 12V, which require a dedicated transformer or driver to operate, and GU10 at 230V, which connect directly to the mains without the need for external power supplies. The choice between the two types depends on the existing system configuration and design preferences.

LED bulbs: the most efficient and versatile choice

LED bulbs are today the most widely adopted solution for any application, thanks to low consumption, long lifespan, and constantly improving light quality. They are available in nearly all sockets and offer a vast selection in terms of:

• Color temperature: from warm white 2700K to natural light 4000K, up to cool white 6500K
• Wattage: from fractions of a watt up to over 20W, with luminous output comparable to or higher than traditional incandescent bulbs
• Shapes and diffusers: drop, olive, spherical, globe, candle, tubular, reflector
• Dimmable versions compatible with the main dimming systems

Vintage LED filament bulbs

For those seeking a retro aesthetic without sacrificing energy efficiency, we offer a complete line of vintage LED filament bulbs: the same warm and evocative light of historic Edison incandescent lamps, with the energy consumption and durability of modern LED technology. Perfect for exposed pendant lamps, designer chandeliers, commercial venues, restaurants, and industrial-style environments.

Halogen, fluorescent and metal halide bulbs

Despite the spread of LED technology, some applications still require traditional technologies: halogen bulbs for applications requiring very high color rendering, compact fluorescent lamps for utility lighting, and metal halide discharge lamps for lighting large spaces, commercial displays, sports facilities, and museum applications. Our range also covers these specific needs.

Reference brands

Among the leading manufacturers featured in our selection: Osram, Philips, Lampo Lighting, and Shot Bot Lighting. Brands internationally recognized for the quality of their components, the reliability of declared performance, and compliance with European technical and safety standards.
