Features and Benefits

Ceravision's High Efficiency Plasma technology platform has produced a very bright compact light source with an optically clear waveguide to enable emitted light to be collected for controlled distribution.

Tailored Spectral Output: The absence of electrodes enables excellent flexibility in the choice of dose chemistry.  Using a tailored chemical dose allows the spectral output tobe accurately specified.  This means that the ionCORE™ light engine is ideally suited to horticulture grow-lights customised for specific plants.  Our work has also identified opportunities for a UV-C spectrum for sterilisation.

Improved Lifetimes and Lumen Maintenance: The most common failure mechanisms in traditional discharge lighting technologies are the electrodes and the metal-to-glass seals.  With no electrodes in HEP these failure mechanisms are eliminated and this ensures longer life and class leading levels of lumen maintenance of 90%.

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.

Good Vertical & Horizontal Illuminance: ionCORE with its small, single point source lamp has enabled us to design an efficient reflector, which distributes light along vertical surfaces whilst maintaining high horizontal illuminance.  This characteristic is important in horticulture to ensure that the light penetrates into and through the plant canopy - perfect for uniform plant growth.

Uniformity: The small light source combined with a good reflector design provides excellent uniformity to ensure that our grow-lights distribute light uniformly throughout the crop to ensure consistent plant growth and development over a wide area. 

Fully Dimmable: The HEP lighting system can be fully controllable, with real–time dimming capability down to 30% 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: Power outages may be, they are a fact of life.  In the event of a power outage, our luminaires will cool sufficiently to enable a full restart within four minutes.

Flicker-Free Output: Flicker is '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, can cause varying levels of flicker.  The human eye doesn't perceive this flickering but new modern film and television cameras operating at very fast speeds can.  This can be particularly noticeable during slow motion replay of recorded filming.  Ceravision's plasma lighting operates at microwave frequencies and is thus effectively flicker-free.

Broad Spectrum Light: The standard ionCORE™ light engine provides a broad-spectrum ‘daylight’ quality light.
