Features and Benefits

Through the combination of a number of scientific and technical innovations, Ceravision's High Efficiency Plasma technology platform has produced a very bright compact light source but with low glare. The use of an optically clear waveguide enables the light emitted by the plasma source to be collected for controlled distribution.

Improved Lifetimes and Lumen Maintenance: The most common failure mechanisms in traditional discharge lighting technologies are the electrodes and the metal-to-glass seals. HEP does not use electrodes: removing the electrodes from our plasma technology has removed these failure mechanisms. And with the ability to introduce a highly efficient chemical mixture this creates superior light with longer life and class leading levels of lumen maintenance of 90% and more.

Small Source Size: The relatively small size of the quartz lamp allows Ceravision to collect more than 90% of the generated light, dramatically improving energy efficiency even further.

Electronic Control Gear: The electronic control gear is integral within the ionCORE™ light engine. The system contains all of the essential elements that are offered separately within other lighting technologies and which add to their power consumption.

Good Vertical & Horizontal Illuminance: Vertical Illuminance is the amount of light falling on a vertical surface or plane. For example, this is particularly important in a sports environment where objects move at speed. ionCORE with its small, single point source lamp has enabled us to design an efficient reflector, which distributes light along vertical surfaces whilst also maintaining high horizontal illuminance. This is perfect also for horticulture lighting and uniform plant growth.

Uniformity: The small light source combined with a good reflector design provides excellent uniformity.

Good Colour Rendering: For visible lighting applications the ionCORE™ light engine can produce spectra that deliver excellent levels of colour rendering with CRI in excess of 80. This means that objects colours are shown truly and naturally and provides pleasant environments for people.

Lighting Controls: The software incorporated into the power supply has full functionality to enable users to control and monitor individual lamps and/or complete lighting systems from one central command centre locally or remotely.

Fully Dimmable: The High Efficiency Plasma lighting system is fully controllable, with real–time dimming capability down to 50% of system power and with a comparable reduction in power consumption. This enables fixtures to be utilised very effectively to deliver specific local task lighting requirements as and when required.

Rapid Re-start: However uncommon power outages may be, they are a fact of life. In the event of a power outage, our luminaires will cool sufficiently within a 6-minute period to enable an automatic restart; this system is built in to the luminaire firmware and happens without user intervention.

Flicker-Free Output: Flicker is defined as 'the impression of unsteadiness of visual sensation induced by a light stimulus - the fading and brightening of a light source at any given rate. Traditional lighting systems operate between 50 Hz and several kHz, which can cause varying levels of flicker in certain applications. The human eye cannot perceive this flickering but new modern film and television cameras operate at very fast speeds and can capture the flicker from traditional lighting systems. This can be particularly noticeable during slow motion replay of sporting events. Ceravision's plasma lighting operates at microwave frequencies, and therefore is effectively flicker-free and thus overcomes any undesirable or in some cases hazardous flicker effects.

Broad Spectrum Light: The standard ionCORE™ light engine provides a broad-spectrum ‘daylight’ quality light. Productivity and safety are linked to the quality of light provided in working environments.

Tailored Spectral Output: The absence of electrodes in the ionCORE™ light engine enables absolute flexibility in the choice of dose chemistry. By incorporating a wide range of chemical doses the spectral output can be accurately specified from anywhere in the spectrum to deliver tailored light. This means that the ionCORE™ light engine can be used across a range of applications for visible light applications, UV sterilisation and for horticulture grow-lights customised for specific plants and outcomes.

Future Markets & Applications

Energy efficiency is a global driver within many markets and Ceravision’s core technology has the ability to address these markets. Due to the flexible nature of the technology we are able to facilitate a variety of power levels (400 W to 2.0 kW) and spectra ranging from visible to UV light.


Ceravision’s High Efficiency Plasma (HEP) light is particularly suited to medium and high power applications. The light is emitted from a very small source, which enables Ceravision to accurately focus and distribute the light. This in turn facilitates significantly greater optical performance.
