UV420 Launched at Autopot Show

Working closely with The Greenhouse Effect Hydroponics Ltd (https://ghedirect.co.uk/), Ceravision is exhibiting the new UV420 High Energy Photon unit at the Autopot Summer Special show on 18th and 19th August .

Described by Greenhouse Effect as the 'Next Generation Grow Lighting', the UV420 offers larger yields, higher quality and better crop protection. 

The UV420 Luminaire produces not only high intensity visible blue spectrum light but also provides increased levels of ultra violet (UV) light (UV-A, UV-B).

UV420 at Amsterdam Greentech Show

A ground-breaking new lamp that is ideal for maximising plant growth is being launched by UK lighting pioneer Ceravision Ltd at the Greentech show in Amsterdam in June 12-14 2018.  Ceravision Commercial Director, Stuart Stoddart said "Not only does the lamp and patented spectrum provide an exceptional alternative for growers seeking to increase photosynthetic rates, yield and disease resistance; its exceptionally high output means one Ceravision UV420 can replace at least two conventional lamps .  No other lamp can offer similar performance.."

Ultra-long lamp life is another core feature of the Ceravision UV420 lamp.  This was developed by a team of brilliant scientists at Ceravision, based in Milton Keynes.  The recently invented lamp dose combines a unique process in which the materials are evaporated within the lamp, which results in no chemical reactions, resulting in near-zero degradation.  Ceravision's chief scientist, Barry Preston remarked: "After extensive testing we are yet to locate failure mechanisms."  As a result, whereas metal halide lamps last just 10,000 hours and standard LEDs around 20,000 hours, the Ceravision UV420 lamp has an average life of no less than 50,000 hours.

The significance of the UV output is outstanding, said Stuart.  Growers who identify with secondary photomorphogenic plant responses and UV will see major benefits, including growing medical cannabis and biotech companies involved in plant taxa for medicine.  The UV420 lamp has been tested both at the Rothamsted Research station in Hertfordshire, UK, and at a multinational's experimental science centre in Cambridge.

Julian Franklin, head of controlled environment agriculture at Rothamsted Research, confirms that during trials with LED's and metal halide lamps, Ceravision's HEP lamps were the best performing technology in some key areas like embryo development, essential for plant health.

Mr Stoddart added: "The UV420 gives plant growers increased levels of UV-B, which can lead to increased yields of up to 30%, and better quality crops with higher nutrition levels."

Ceravision High Efficiency Plasma Lamps Outperform LEDs & Legacy Lamps in Scientific Trials

The testing of Ceravision’s High Efficiency Plasma (HEP) lamps in Rothamsted and in commercial premises has been underway now for severalmonths. The testing compares Ceravision’s HEP grow-lights with legacy metal halide lamps and new LED systems and their impact upon the growth of wheat and other high value crops.

Ceravision’s HEP lamps are outperforming both the metal halide lamps and the LED systems in Embryo Development, a key performance metric in respect of plant development.

Rothamsted Research in Harpenden, England is the oldest agricultural research station in the world.  Rothamsted’s aim is to deliver the knowledge and new practices to increase crop productivity and quality and to develop environmentally sustainable solutions for food and energy production. 

Mr Julian Franklin, Head of Horticulture and Controlled Environments at Rothamsted said that observations in the wheat crop under trial proves that the Ceravision luminaires are producing the best results compared to metal halide lamps and LEDs in respect of embryo development - one of the major factors in plant growth and plant development.

The embryo of a plant is key to its reproduction and growth.  The ‘wheat germ’ is the embryo of the wheat kernel which is separated in milling and used especially as a source of vitamins and protein in a variety of food products.

The 430W HEP lamp light quality was better and the impact of having light available in the blue / UV region within the broad spectrum is a significant factor. 

Building on this work , Ceravision has now launched its new UV420W grow-light.  This unique grow-light produces not only high intensity visible blue spectrum light but also provides increased levels of ultra violet (UV) light (UV-A, UV-B). 

Mr Stuart Stoddart, Commercial Director at Ceravision, said “This is fantastic news; and this is with our standard ‘white light’ spectrum.  We are excited about the combination of higher output and spectra tailored for plant growth and the benefits that will be delivered.  This confirmation of Ceravision’s HEP technology suggests an exciting future for Ceravision against a background of the challenges faced by mankind in operating efficient food production systems to feed more people, and the huge medicinal benefits that can be obtained from plants.”

Ceravision Limited leads evening event to mark UNESCO International Year of Light

A rare opportunity to hear about the ‘Science of Light’ is taking place at a special event at the Open University on Tuesday 31st March.

The evening will be of interest to anyone seeking a career in engineering, physics, electronics and lighting, or simply fascinated by cutting-edge science.

The free-to-attend event is being sponsored by Ceravision Limited, one of the UK’s most innovative companies, Ceravision is the creator of a ground-breaking high output lamp technology called ‘High Efficiency Plasma’, which is able to produce applicational solutions in areas such as stadium lighting, high-bay lighting and floodlighting.

The event is being held to mark the 2015 UNESCO International Year of Light, a year-long celebration of the impact and achievements of lighting ‘to energy, education, agriculture and health’.  In fact, few technologies have contributed as much to mankind’s progress since the late 19th Century as electric lighting.

The evening will begin with a recorded introduction by the renowned environmentalist campaigner Jonathan Porritt CBE, who is also an advisor to Ceravision.  Today, as Mr Porritt will point out, a significant number of people in the developing world still have no access to lighting.

Following Mr Porritt’s introduction, Ceravision Engineering Manager John Stocks will describe the ‘Non-Visual Impacts of Light’.  Whilst light allows us to see, it also has many other, little-known effects on our bodies and biological systems. 

“From circadian rhythms to Seasonal Affective Disorder, light has a far greater impact on our everyday lives than we ever imagined,” explains Mr Stocks.  It’s exciting to take part in the Year of Light and explore this rapidly developing field.”

Two further talks by Open University Researchers will follow: 

Lucia Marchetti, on ‘Cosmic Light: the story of everything’, and

Calum MacCormick, ‘How to slow atoms with light: how to slow light with atoms’.

Event Details:

Venue: Berrill Lecture Theatre, Open University, Walton Hall, Milton Keynes, MK7 6AA.

Doors open: 18:00, presentations start at 19:30. 

Free to attend: No booking is required.
