Discharge bulbs
Discharge Lamps: the Complete Range at Diffusione Luce
Diffusioneshop.com offers a complete range of discharge lamps, light sources mainly used in industrial applications, street lighting, and technical systems where high powers and significant luminous fluxes are required.
Available technologies
- High and low pressure sodium vapor lamps: used for street lighting, with high luminous flux and lifespan over 30,000 hours
- Metal halide lamps: characterized by high color rendering, used in sports field lighting, warehouses, projector floodlights
- Mercury vapor lamps: traditional technology still present in some older installations
- Compact fluorescent lamps: for residential and commercial use
Technical features
Discharge lamps require a dedicated ballast for proper operation and have non-immediate switching on and restart times: a few minutes to reach full power, and up to 15 minutes of cooling after switching off before they can be turned back on.
LED retrofit
Today most discharge applications can be effectively replaced with equivalent LED solutions, achieving energy savings up to 60%, instant switching on, and drastic maintenance reduction. If a product shows zero availability, it can still be ordered on request: average delivery times are shown in the product page.
