Light Emitting Plasma (LEP)
Light Emitting Plasma (LEP) is an energy-efficient and powerful light source that uses a plasma arc instead of a filament or LEDs. LEP technology combines the advantages of high-intensity lighting...
Read moreAlternative light sources
In addition to conventional lighting such as incandescent bulbs, fluorescent tubes, and LEDs, various alternative light sources have been developed for specific applications. These range from sustainable energy options to...
Read moreCarbon arc lamp
A carbon arc lamp is an early form of electric lighting in which light is generated by an electric arc between two carbon electrodes . This type of lamp was...
Read moreFresnel spot
A Fresnel spotlight is a theatrical and film lighting fixture with a Fresnel lens , which produces a soft, evenly distributed beam of light . This type of lamp is...
Read moreLEKO (Ellipsoidal Reflector Spotlight – ERS)
A LEKO is an ellipsoidal reflector spotlight (ERS) , a type of theater and stage spotlight that produces a powerful, focused beam of light . The name LEKO comes from...
Read moreHMI lamp (Hydrargyrum Medium-arc Iodide)
A medium-arc iodide (HMI) lamp is a high-intensity discharge lamp (HID) used in film, television, photography, and theater . These lamps produce a very bright, daylight-like light (5600K) with a...
Read moreDichroic filter
A dichroic filter is an optical filter that selectively reflects or transmits specific wavelengths (colors) of light. Unlike traditional color filters, which absorb light, a dichroic filter works by interfering...
Read moreBleed Through
Bleed-through is a phenomenon in lighting and signage where unwanted light shines through a surface , making the final result look less polished and professional. This can occur with: 🔹...
Read moreNeon light
Neon light is a type of gas discharge lighting in which an electric current is passed through a glass tube filled with a noble gas (usually neon). This creates a...
