The Light Review at [d]arc room 2019

For all those who couldn’t make the show, The Light Review let Chris Fordham, our resident product reviewer, loose among the exhibitors to see what might take his fancy.


Sitting on the site of what was at one point the world’s largest brewery, I did wonder what our Victorian forbears would have made of the furniture, lights and Campari stand situated outside of this year’s [d]arc show entrance. They certainly would have been shocked and in awe at the miniscule dimensions and functionality of some of the luminaires on offer (as indeed I often am), though probably less surprised at the long queue for free alcoholic beverages; after all some things never change!

This is the third year that the (d)arc show has exhibited. Its aim is to present products to an extended design audience in a creative way, with a display template that ‘gives freedom of choice and takes the stress out of stand building’. I was told this also avoids the larger companies building massive stands and crowding out the tiny ones; here the lighting does the talking, regardless of your size.


OZ from Targetti

The new Targetti OZ product is following a trend in the industry seen in the past few years, utilising magnetic track.  Marketing manager Cesare Coppedè talked me through the product and some of its features.

Targetti’s OZ – ‘something small’

At the beginning of the design process they were looking to ‘develop something small which could be easily installed on the wall or ceiling, which was both easy to adjust and specify’. The ‘OZ’ lighting module system (as in The Wizard of OZ, Cesare tells me), incorporates all of the elements that are used in the family, ie OZ magnetic track, OZ profile, OZ projectors etc. The new projector, (that shown at the show is a prototype) will be available with LensVector technology, meaning that one fixture will be capable of providing a variety of beam angle, as the beam can being adjusted remotely via an app. It also incorporates Casambi dimming.

Competitively priced, the track is easily cut, with no special tools required. Drivers can be mounted remotely or attached to the track itself. The track comes with L-connectors, T-connectors etc and can be mounted with adhesive tape or screws.

 Cesare however would recommend screwing the product to the wall or ceiling for obvious reasons, one of the tracks most useful aspects is its ability to remove and adjust fittings by simply pulling them off, you wouldn’t want the track to be pulled off at the same time, even if they have been earthquake tested for resilience and stability !

The first projector with the LensVector technology to be produced will be the small version, which is available with either a fixed or adjustable head, with a lumen output of around 180 lumens, (this varies slightly according to the beam angle used). LEDs used in the product are either Nichia or CREE. In the larger version a ‘COB’ from Citizen is used, kicking out a massive 800 lumens, though I am told that, due to the massive gap in output between the large and small versions, they may eventually reduce the output in order that this version fits more easily with the rest of the range,. Colour temperatures available as standard are 2700,3000,3500,4000 K and all LEDs are RA 90.


Centura from Radiant Lighting:

Released last year and shortlisted in the Lux awards, Radiant Lighting was displaying the innovative Centura product. The product is a flexible LED interior linear lighting system and has an almost ‘spinal’ aesthetic. Managing director David Morgan tells me ‘The Centura design evolved from reactions we had from specifiers to a version of the 3D LED Flex 40 system, with twin-colour extruded snoots. The main difference from the 3D LED Flex system is that the Centura only bends in the horizontal plane.  This helps to make it quite rigid in the vertical plane so that suspension points can be as widely spaced as possible.’

The product comes as direct or indirect, surface-mounted or suspended; and with lumen outputs of up to 5000lm per metre, it certainly has the output to suit many applications. The modules can either be linked with a lockable hinge for adjustable on-site systems or can be mounted onto a preformed frame for fixed shape pendants.

One of the products main design features is its ability to follow curved surfaces, encapsulating domes and columns, and to make irregular shaped pendants. The louvres are available in any RAL colour with gold (as shown above) adding a touch of class.

The product has a variety of LED options depending on the luminaire type. Cree XPE or XPG LEDs are used for most lensed downlight projects and if higher CRI levels are needed, Oslon Square LED with lenses.

For the up-lighting modules Citizen LEDs, Cree or Luminus COB LEDs are specified, while the RGBW products have the Luxeon CZ LEDs with Gaggione lenses. Finally, the diffuser downlight version uses Luminous mid-power LEDs.

The number of LED variants reflects the level of detailed design that has been employed in making this luminaire, a British manufactured product, made by a lighting designer, for lighting designers.

Traceline from Reggiani

A question for you, how long does it take to make the perfect linear lighting system? Well according to Reggiani lighting around four years!  In around 2015 Stephen Philips, the leader of industrial design at Arup, was approached to create ‘some kind of linear lighting system for architecture’. This was initiated at the same time as Reggiani started a global rebranding exercise, where they adjusted and trimmed their range to be more in tune with architecture and design, a little sharper and more performance based.

My first question to Stephen was what differentiated this product from all the others, with the plethora of ‘lookalike’ linear systems on the market. Stephen told me;

“The phrase ‘lighting for architecture’ came up in our first design meeting, which made us think about how we could do this differently and in a comprehensive manner. Our approach, instead of just going to the drawing board and designing something, was to look at Reggiani, see what their current products were, their strengths, and how we could play to them.”

The Arup lighting team, with industry names such as Florence Lam and Arfon Davies, were all collected together and interrogated about what for them made a good product. The result is the new ‘Traceline System’ a series of linear luminaires whose variants are available as deep recessed, recessed, surface mounted, a pendant or deep pendant mounted version, with the ability also to insert track and Yori spotlights. They are also available with an impressive number of optical options and finishes.  

The product is available in CRI >90 with LED temperatures from 2200K to 4000K, with the option of CRI of >95 using a 3000K variant. Also, on offer is a tunable-white version, and a wide selection of control options, Dali, 1-10 V, Push Dim and Bluetooth. Its dimensions are certainly reflective of its name, being a mere 20mm width in the recessed product and 24mm in the suspended.

Stephen tells me “There was a desire to make it slim, discreet, and scalable, something that was more of a toolkit, you can use ‘Traceline’ as a recessed continuous length and integrate the ‘Yori Ghost Track should your design require accent lighting, if you adhere to the spacing requirements.” All in all, the ‘Traceline’ does indeed seem to fulfil all the design requirements required from this type of product, and I look forward to seeing them used in architectural projects soon.


And that’s all from our roving reporter until the next gathering of lighting excellence in the UK, which will be at LuxLive in November, and we’re all waiting to see what the new show owners have to bring to Europe’s largest annual lighting event.



But we mustn’t forget that your intrepid editor will be travelling to Rotterdam in a couple of weeks for the PLDC, the annual Convention created for the global lighting design market. The Light Review is a Media Partner for the event.
