Niches filled with coloured light
Cabot Square in the centre of Bristol took over three years to build and costing in excess of £500 million, providing city centre visitors with over 120 new shops, including 15 major flagship stores.
The three-tiered shopping development will also provide space for many new restaurants and the UK's third Showcase Cinema de Lux, offering 13 screens, three of which will show films in 3D.
This incredible development in the heart of Bristol is covered by a unique shell-shaped glass roof; the only one of its kind in Europe.
Crescent CLO linear LED system is used to light a number of areas around the centre including the roof itself as can be seen in the above image.
In a number of areas the system is used to graze light up or down walls, & in one case blue light across a textured wall, turning it into a notable feature.
On the external wall adjacent to the car park link bridge it is used to fill the niches with coloured light as can be seen from the right hand image.

Lighting designers for the project were Tim Downey & Ian Payne at Pinniger & Partners.

Sands Hotel, St Barts

The Sand Club hotel, situated on Flamand beach, is in a superb position on the northern part of the tiny Caribbean island of St Barts.
The Hotel has guestroom villas, a games room, a pool and staff quarters. It was lit by Firefly Design, who used a number of innovative methods to achieve a minimalist effect with low energy consumption.

The pool uses concealed LED strip lights from Crescent just above the water line, which are hidden from view so they provide no glare whatsoever. The linear system with 120 LEDs/metre is resin filled to achieve its IP68 rating
Crescent also supplied a large number of recessed square paver fittings with warm white LEDs that were used around the exterior of the hotel.
This fixture has also been utilised in some of the villas where they have been made fully dimmable, to create a subtle, calm effect.
All exterior lighting is low-wattage, high-output LED as energy is at a premium on the island.

Blackfriars Bridge


The lighting in an area leading up to Blackfrairs Bridge in London has been revamped by lighting designers Firefly using Crescent CLVS linear colour changing RGB system. Seventeen lengths of the slim profile were installed behind curved mirrors above a pedestrian ramp area on the north bank entrance to the bridge, to shine up into the bridge structure.
The lighting system was programmed by Crescent with strict instructions for no red, blue or green alone to be used, but subtle mixtures of the three colours.
The programme runs daily from 3pm to 9am and has a static gold colour for the first 55 minutes followed by a ripple of cool colours along the length of the modules for 5 minutes.
The next 55 minutes has the gold fading back & forth with yellow before the ripple effect starts. Then yellow is the static colour before the ripple again. This sequence is repeated for the rest of the programme with other static colours replacing the yellow and a cool ripple replacing the warm one at 4am.
Peter Veale of Firefly commented:
"We did the project with the architects The Facility. It was quite a tight budget project and we wanted to create an animated colour-changing design where the fittings and drivers were hidden behind the reflectors, but the effect still needed to be visible from the other side of the river. All equipment had to be durable against the elements and we knew that the Crescent CL fittings were up to the job."

C'an de Rosen


C'an de Rosen is a large private house on the coast of Mallorca. VBK Lighting were appointed early in the project and were able to influence the design enough to conceal most of the light fittings to complement the minimalist interior. The main image above shows the deck & pool at the back of the building with CLO recessed to illuminate the facade . Fluorescent and LEDs were used extensively inside, the linear CLC system shown below in the utility area, TV room and other detail niches. In addition, Agabekov 'B' Light linear xenon lighting, and LED pavers were used in other parts of the project.

New LED Lightprojector at Arc09
Despite freezing temperatures, ice snow and traffic chaos Arc was very successful for us again this year, well done for those who braved the weather to come & see us! We were very happy with our stand position in the middle of the hall (next to the bar - a very good move for the Wednesday night drinks reception) and the open layout o the stand seemed to work well. Most people were impressed with the new LED fibre optic projector recently launched by our parent company, Energy Focus Inc, which is shown on the right hand side, below.

on the LED projector

This very neet little unit with an impressive performance and a comprehensive colour control specification was our 'star ' of the show. It is actually brighter than a 150WHQI projector in red magenta and blue colours, with a power rating of only 40W! Indoor and outdoor versions are available and there is also an 18W fanless model. Still to come is a white light version which can be switched to different colour temperatures, full details on this site very soon.

Some of the other new products at at Arc for the first time are shown below.

Grand Mosque wins MELDA award

Named after His Highness Sheikh Zayed Bin Sultan Al Nahyan, the late President of the UAE, the Grand Mosque in Abu Dhabi was opened late in 2007. The structure covers an area of more than 22,000 square metres and some 210,000 cubic metres of concrete and 33,000 tonnes of steel reinforcement was used in its construction. It is the largest mosque in the United Arab Emirates and the world's third largest one. Each of the four minarets rises to a height of 107m, with the main dome reaching 80m.

Islamic Floral detail

Winning best interior lighting design in the Public Building Category of the 2008 Middle East Lighting Design Awards (MELDA), Speirs and Major Associates were also awarded 'Middle East Project of the Year' for their stunning design.

In the central hall the Qibla prayer wall was decorated with Islamic floral designs and gold mosaics. Crescent Lighting worked closely with Speirs and Major Associates to provide a fibre optic lighting system to do the design justice.

More than 2000 metres of BPAK150 optical cable were used, powered by CREAD068 projectors manufactured by Crescent's parent company, Energy Focus. The side emitting fibre optic cable mimics the designs cut into the marble cladding. The cable is fixed behind the marble and throws light onto white reflector behind, the design seeming to 'glow'. (See Fig.1)

A similar approach was taken with the script cut out in the marble.
This time the Lightbeam QR linear profile was used to throw light back onto the glass material behind the cut outs. (See Fig.2)

Keith Bradshaw of Speirs and Major Associates explains:
" The Energy Focus projector and Lightbar fitted the requirements of the design like a glove. We tested many different light sources but found that the fixed angle focus of the Lightbeam illuminated the inner gold curtain detail in an even manner yet with a certain sparkle and brilliance which suited the material. The installation frame and support for the wall was very complex and the Lightbeam was very well suited to fix discreetly to the mounting channel of the marble wall."

Nintynine two-metre lengths of Lightbeam QR were fitted and these again were powered by the CREAD068 I projector, well over 200 being supplied to the whole project.

The Energy Focus CREAD068 projector is unique in having a patented Compound Parabolic Collector (CPC) at the very heart of the optical system. The CPC collects the light generated by the 70W AC HQI lamp directly from the arc tube and at the same time directs the light beams to the ideal angle (35 degrees max) to efficiently launch the light into the fibre.
The CPC non-imaging system mixes the colour, giving a very even distribution, and then feeds it out in two outputs to the fibre.

"The double output CREAD068 is very efficient in terms of the efficacy at transmitting light into the harness. We found the single 70W HQI double output unit gave the same relative intensity as conventional single output 150W HQI projector" commented Keith Bradshaw.

Light and Building, Frankfurt 2008

Frankfurt was successful for us again ths year. As usual we shared the stand with Energy Focus and our sister company, LBM. Bernhard and the LBM team did a great job with the stand design yet again, and there was a good mix of functional and decorative products,fibre optics and LEDs. The images that follow show some of the new products on the stand.

 

This view shows some of the decorative products with Laluna, Vino and Medusa all suspended around the comfortable seating areas.

The new Low Energy downlight range were located in vertical slots around the outside, two of these features can be seen here.

   
The Vino range has been extended with the addition of two new products, Vino Leaf, below, and Vino shade, shown left. The two original designs are shown illuminating the counter tops of the stand, on the right.
The Vino Leaf is a more organic aproach to the contemparary pendant luminaire, but whatever the design influences the whole Vino range provide strong, controlled downlight output, especially when connected to the EFO projector.
One of the products that caused the bigest stir was Lucemento which is a really fantastic concrete material that transmits light! This is an amazing product with endless possibilities.
A finely woven fibre optic material is cast in precisely spaced layers within a compressed concrete substrate. This is then sliced up into a number of standard thicknesses. Any light pattern is transmitted through the fibre to the front face of the material.

Crescent at Arc08

We had two stands this year at Arc08, our normal position on the mezzanene level which showed the LED linear wall wash system and some new downlights with LED or HID lamps, (the downlights all comply with the requirements of Part 'L' of the building regulations), amongst other things. We also showed products on our second stand,on the decorative gallery.

 
Our main stand with the new downlights in the display 'Pods'.
 
 
        The three new Pat 'L' downlights shown at Arc08. A data sheet will be available on these products very soon.
 

CRE2550 Laluna

The decorative stand upstairs on the gallery level showed Ufo, Scintilla and some wall mounted LED options, such as the CRE 2711 square glass unit, shown below.
The star of the stand was, as usual, Laluna. Mounted a little lower than normal, visitors wanted to touch it, entranced by it's ethereal beauty. Most were suprised that the prices start as low as around £500 including a TH projector.

New Fibre Optic pendants at 100% Design

We are exhibiting at 100% Design for the third time, with another eye catching display featuring the stunning Simon Bruenner designed ufo fibre optic pendant fitting, shown on the left above. The ufo glass disc seems to float, connected only by the fibres that feed out from the centre -it is really an arresting design & we are looking forward to the reaction from the visitors at the show!
On the right above is the new Scintilla, also designed by Simon, a fragile, minimal design which combines fibre optic technology with the classical features of historical chandeliers. Scintilla creates subtle, seductive lighting with the possibility of exciting colour change effects if required. The state-of-the-art materials lend an atmosphere of simplicity.

Also new for the show this year will be a number of new wall mounted LED products and a new linear wall wash LED system. We are particularly pleased with wall wash product as it can light a wall with better than 2:1 uniformity - made possible by a special lens design & carefully constructed extrusion section. It uses the latest Luxeon K2 LED and works very well when operated at 700mA. We hope to be able to demonstrate its performance on the stand - see you there!

Crescent win at Arc07


The Arc07 exhibition was particularly successful for us this year. We designed at stand with a much cleaner, uncluttered look, but which still showed a lot of new products. The new recessed LED products and the prototype of a unique wallwash LED system were installed in the white demo 'bins' seen above, so that they could be demonstrated but didn't spoil the softer feel of the area. Laluna created a lot of attention, as usual.
The walls were lit with the CLS system which created an interesting edge lit effect on the extrusion shapes and logo outline.
Many people complemented us on the design, but the icing on the cake was to win the Arc07 & Society of Light & Lighting 'Best Stand Design' award.
Well done the Crescent design team!

Part 'L' Need Not Be Dull
The recently upgraded Crescent EFO (Efficient Fibre Optics) projector delivers over 45 luminaire-lumens/circuit watt meeting the requirements of L2A and L2B for new and existing buildings. This figure is actual delivered lumens and takes into account both the efficacy of the lamp and the LOR of the luminaire.
The EFO projector is manufactured by Crescent's parent, Fiberstars, and has had a modified, higher output cloverleaf lamp reflector profile added in recent months.
The EFO system using six or eight tails has been independently tested by ITL of Colorado and gives just over 50 luminaire-lumens/watt easily exceeding the minimum requirements of Part L for both domestic and commercial buildings.
This will enable the 'small downlight' look to be used to provide a variation in the lighting effect around the edge of large areas, to wall wash, light corridors, lift lobbies, reception areas meeting rooms.


EFO is also a very useful tool in helping designers meet the demands of Part L (L1A and L1B) for private houses where it can add much needed sparkle in comparison to cfl downlights.
This enables the owners' preference for tungsten downlights to be offset by using EFO in both the decorative and working areas of the home.

The projector houses a 68w metal halide lamp with a rated life of 10,000 - 14,000 hours. This is focused using the unique 3-way or 4-way cloverleaf reflector, via quartz rods through to the fibr
e.
