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 light source with unparalleled levels of energy efficiency. Ceravision is able to deliver exceptionally high lumens per watt because of the unique construction of our integrated resonator/burner and specifically, the use of an optically clear waveguide that enables the light emitted by the plasma source to be collected for controlled distribution.

The absence of electrodes enables absolute flexibility in the choice of dose chemistry, giving our lamp designers and partners the freedom to select high efficiency doses otherwise unavailable from electroded lighting systems. Furthermore, there are no additional ballast losses or power factor correction issues to consider with High Efficiency Plasma lighting systems (to the overall power stated). Ballast losses present a serious drawback to conventional lighting systems that typically incorporate either traditional or electronic ballasts.

As a result of all these features, the Ceravision High Efficiency Plasma lighting system draws substantially less energy for the same light output on a system watt basis, compared to alternative electroded and electrode-less lighting systems.

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. For the general lighting market in particular, the superior luminaire efficiency that Ceravision can offer equates to a reduction in energy consumption and capital expenditure.

Improved Lifetimes and Lumen Maintenance

The absence of metal electrodes significantly increases the lifetime of our lamps in comparison to alternative lighting solutions and means that we can achieve class leading levels of lumen maintenance of 90% and more. The Ceravision High Efficiency Plasma lighting fixtures will deliver 90% of stated lumen output over the lifetime of the system, which is superior to incumbent devices, some of which have a lumen maintenance of 50% after just 1,000 hours of operation.

Dimming Capability

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 offers customers a genuine opportunity to reduce actual energy consumption and enables fixtures to be utilised very effectively to deliver specific local task lighting requirements.


The software incorporated into the power supply has full functionality to enable users to control and monitor either individual lamps and/or complete lighting systems from one central command centre. This allows responsive control from any remote location giving the opportunity for even greater energy savings whilst ensuring that every lumen produced is utilised effectively.


The most common failure mechanism in traditional discarge lighting technologies are the electrodes.  Removing the electrodes from our plasma technology has enabled Ceravision to use a more efficient chemical mixture to create superior light over a significantly longer period.

With the absence of electrodes, Ceravision is able to offer flexible dose chemistry.


The core technology provides a platform to design and build into a multitude of different applications. Ceravision can provide complete lighting solutions within the 400 W – 5 kW power range.

Recyclable Technology

The Ceravision HEP lighting system is 80% recyclable with no specific disposal requirements.

Flicker Free

Traditional lighting systems operate between 100 Hz and 120 Hz 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 2.4 GHz, which is effectively flicker free and thus overcomes any undesirable or in some cases hazardous flicker effects.

Broad Spectrum Light

Ceravision's plasma lighting provides a broad spectrum ‘daylight’ quality light. Productivity and safety are linked to the quality of light provided in working environments.  The light source has an excellent colour rendering index with the ability to tailor spectra to suit applications and therefore dictating the required CRI.

Ceravision’s plasma technology allows the choice of a wide range of chemical doses and so the output can be accurately specified from anywhere in the spectrum. This means lamps can be used for a wide range of purposes from visible light to UV applications.

Further Information

Future 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 5 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.

Ceravision maintains an extensive Intellectual Property (“IP”) portfolio comprising Patents, Trade Marks and Design Rights.
