What does QXF mean in PRODUCTS

A QXF (Quartz Fresnel spotlight) is a type of lighting fixture typically consisting of a quartz bulb, reflector and lens system with the purpose of producing intense, focused light over a long-distance range.

Quartz fresnel spotlights are most often used in theatre and stage performances, as well as for outdoor filming and photography. They are also sometimes used to provide extra illumination for indoor filming projects.

The quartz fresnel uses both an internal reflector and lens system to create more intense light than other types of spotlights that rely solely on the bulb for illumination. In addition, the lens allows for precise control over the width of the beam angle which can be adjusted using gels or "barn doors" from outside the projector's frame.

The amount of energy consumed by a Quartz Fresnel varies depending on its size and wattage rating. Generally, they will consume between 500-1000 watts when operating at full capacity depending on their size and model specifications. However, their efficient design means that they can use less energy than other types of lighting fixtures while still providing intense illumination power.

The average lifespan of a Quartz Fresnel is around 2000-2500 hours when operated at full capacity with no interruption periods in between use. However, this figure may increase significantly if it is operated intermittently or at lower power levels since its bulb only needs to be replaced after it has been turned off for prolonged periods of time or if its wattage rating has been reduced through filters or dimmers.
