Hello again,Welcome to the second edition ofEnlightened. However, before Isay anything more let me firstapologise for the problems we hadwith some of our first editionmagazines. Due to anadministrative mistake on our partsome of the magazines weredespatched with the wrong

postage, meaning some people had to payadditional postage in order to receive their copy.

Since the publication of the first edition we havehad the Hong Kong Light Show and the SleepExhibition in London. The big focus in Hong Kongthis year was once again LED, reinforcing our long-held belief that LED will be the major source oflighting in commercial interiors in the very nearfuture. Year on year LED efficacy increases andcosts decrease, making LED not only an energy-efficient option, but also a cost-effective solution.Working with Philips over the last year has alsoconvinced us of the advantages of LED controlsystems which not only control light levels but alsothe colour temperature, allowing operators tocreate the right ambience throughout the day.Having the correct lighting ambience cannot beoverstated. In a working environment the correctlighting has a major effect on a person’sproductivity as it affects both mood and alertnessand in a public space it can be used to governwhether people linger or come and go quickly.

The Sleep Event Europe, which took place on 22,23 and 24 November, received a record number ofvisitors with an 11% increase, confirmation thatthe show is the premier destination for all those

involved in the global design, development of andinvestment in hotels. This year the NorthernLights’ stand was totally lit by LED, furtherdemonstrating our commitment to this technology.(More on Sleep can be found on the inside back cover)

As we start the New Year world markets are still inturmoil and uncertainty over the Euro continues tohave a major effect on investor confidence. Thissaid, the Leisure Industry appears to be buckingthe trend. We are still seeing lots of activity in therestaurant market and new hotels are still beingbuilt. Whilst the Olympics will be having someeffect on the refurbishment of properties in andaround the London area, its effect in the regions,we believe, will be considerably less. However, weare seeing a generally buoyant picture across thewhole of the UK. This could be the result of theindustry catching up after two years of little or noinvestment, but we will have to wait and see.

In our first edition we had anarticle featuring a pendant thatwas designed by Blacksheep forJamie’s Italian, Islington. In thatarticle we showed images fromseveral Jamie’s Italian sites, oneof which had been designed byStiff and Trevillion. We did notmake this clear in the article and apologise for this oversight.

The ChaoPhraya Restaurant Group takes itsname from the main waterway in Thailand andis pronounced “Chao-pi-ya”. In ancient timesthe Chaophraya river breathed life into thefamilies who lived along its banks. Today theriver is still regarded as part of the essence ofThailand.

ChaoBaby, Meadowhall

“The ChaoPhrayaThai restaurant brandoffers Northern Lightsthe chance to dowhat we do best......to take a concept and theme from ourinterior design clientsand turn it into stunning lighting elements which deliver both in looksand performance”

- Neil EdmundsNorthern Lights Lighting Designer

For the past two years Northern Lightshave been working with JonathonMorgan from JMDA to create a blend oflighting that reflects not only thecenturies old tradition of fine Thaidining and the hustle and bustle of thestreet market food stalls, but also theglitz and glamour of contemporarycocktail culture.

According to the ChaoPhraya Group itall starts with the river. The designtwists and turns such that eachrestaurant has a subtle new look. Justlike the river new vistas appear butthe river remains constant as does thebrand .

ChaoBaby - MeadowhallSheffield’s Meadowhall is one ofYorkshire’s largest shopping malls. TheOasis is the dining quarter at the heartof this busy shopping centre.ChaoBaby is a Thai banquet styleexperience replicating Thailand’sstreet market culture with all of itstheatre, sights and sounds.

Designing the lighting for this schemeposed a number of challenges. Beingin the middle of a large dining hall therestaurant had no well-definedboundaries. A large pendant designedaround a Thai symbol was created.Seventeen of these large but very flatprofile pendants were hung throughoutthe restaurant at varying heights. Thestriking pendants provided visualinterest as well as keeping the eyefocused on the immediateenvironment and not the building’sexposed structure beyond.

The jelly- fish is a recurringtheme within the ChaoPhrayabrand and two large featurependants were designed toreflect this. A large torus wascoated with a swirled opticalpolycarbonate film. Thissurrounded a mass of glasstentacles, all of whichcontained pulsating fibreoptics. Combined they had amost dramatic visual effect.

ChaoBaby - ManchesterTrafford Centre

Located in the heart of the TraffordCentre, ChaoBaby brings a Thaibanquet style experience,replicating Thailand’s street marketculture with all of its theatre, sightsand sounds.

Attracting shoppers and businesspeople alike this more laid-backconcept makes diners feel at ease

in comfortable and convenientsurroundings.

The open kitchen provides a focal pointwithin the restaurant and it wasimportant to get the lighting right. Thechosen solution was to provide onelarge ceiling plate with 140 twistedglass pendants. The effect was one ofleaping flames which mirrored the hotflames of the wok cooking below, all ofwhich added drama to the visualexperience.

“It’s all about theDrama”Drama was also the key word when itcame to the main lighting feature inthe restaurant. At 3m by 1.7m andcovered in hundreds of clear, red andamber glass globes the fitting provideda truly visual feast. It was lit by LEDdownlights and weighed in at a littleover half a ton.

ChaoPhraya - Manchester

Set right in the centre of the city theChaoPhraya Manchester offersexquisite Thai fine dining. Set over twofloors the restaurant boasts executiveprivate dining areas, an elegant bararea and the trademark ChaoPhrayaopen kitchen.

Designed to be the ultimate in Thaidining the lighting adds a sense ofluxury whilst keeping the recurringthemes that are a constant throughoutthe Group.

The twisted glass pendants fromChaoBaby Trafford Centre wereagain used in the open kitchen areaas well as in the stairwell area toadd an extra dimension of drama.They appear to leap upwards fromthe floor towards the large templebells which were suspended fromthe second floor ceiling.

In ChaoPhraya the coloured glassglobes used in ChaoBaby werereplaced with clear ‘crackle glass’globes. Lit by LED candle lamps thelight from the lamp is defracted.This creates a striking pattern oflight across the ceiling.

Stiff + Trevillion Light the Way for Jamie’s Italian with Northern Lights

Working With...Stiff + Trevillion have worked alongside NorthernLights for some three years with the Jamie’s Italianchain forming a large portion of this work.

Stiff + Trevillion selected Northern Lights as apartner on these projects because of their ability tofabricate chandeliers from initial design drawingsand sketches, interpreting thoughts and turningthem into reality in a short period of time and to abudget.

Two key Stiff + Trevillion projects have been with theJamie’s’ Italian chain, in their Bristol andCheltenham restaurants. The team at Jamie’s werekeen to maintain the integrity of the buildings and toreflect their past heritage, an ethos Stiff + Trevillionendorsed. Stiff + Trevillion, in conjunction withNorthern Lights, strove to ensure this vision wasfollowed through in each project and in the verydifferent building spaces chosen.

In Jamie’s Bristol there are four principal spacesinterconnected over four floors.The design makesthe most of the complexity of the interior andcreates very different moods in each of the spaces.Stiff + Trevillion sought to reflect the unique historyof the space by commissioning a highly unusualchandelier made of test tubes. This chandelier,situated above the main staircase, is a nod to thework of the physician William Budd who used thebuilding during the 19th Century for his work oninfectious diseases.

Jamie’s’ Italian in Cheltenham is a formermagistrates court. Keen to maintain some thebeautiful fixtures such as the fully intact courtboxes, jury and press gallery, Stiff +Trevillion workedto blend their ideas with the existing courtroom.Many of the original fittings have been incorporatedinto the restaurant design. Again, working closely

with Northern Lights, a bespoke Scales of Justicelight fitting was designed along with smaller lightsreflecting the building’s judicial past.

Another restaurant in the Jamie’s chain, this time inPortsmouth, presented Stiff + Trevillion with adifferent set of challenges, as it was a large retailshell unit with little character. The unit is part of thecity’s recent Gunwharf Quays Development. Stiff +Trevillion instead took inspiration from the historicdocks in which Gunwharf Quays is built. Corrugatedsteel sheeting with super graphics to echo theshipping containers, steel stanchions mimic thegantries, architecture and character of Portsmouth’snaval heritage.Paint schemes take inspiration fromthe razzle dazzle camouflage of the First World Warbattleships. Fixtures and fittings were sourced fromnaval reclamation yards including battleshipbulkhead lights and steel sheeting for the kitchencounter.

The purpose made floor and banquettes drawreference from Italy's design past. From the Sieneseflag with its distinctive wave pattern to the highlylacquered and ornate timber veneer of the Rivamotor launches.

In collaboration with Northern Lights we jointlydesigned the light fittings with glass shades on alarge steel frame that fits in with the navalinfluences of the overall fit out.

This approach, of working in harmony with existingbuildings, meant that many of the fittings for therestaurant interiors had to be designed from scratch.Northern Lights worked closely with Stiff + Trevillionand were able to realise their design concepts tocreate the perfect lighting solution for eachrestaurant.

Swaminarayan Mandir opened in Leicester on the 9 October 2011 and is oneof the biggest in the Midlands. Working with Heterarchy Interior Designers - also

based in Leicester - we supplied 21 Lotus flower inspired pendants to feature in alarge hall within the building: each at 2m diameter.

The gloss finish of the petals on this stunning set of imposing fittings reflects the light of theLED lamps, with gold braided flex to add intricate detail. We also colour matched a deep

red from the elaborate carpet design for the petals in the pendant, to make sure the fittingstied in with the main scheme.

As well as supplying an aesthetically impressivedesign, the practicalities of the installationprocess were also considered. The design of thefitting was split up into a 'first fix' ceiling plate,containing all the lamps and wiring. Fiveseparate tiers of the petals were then suppliedon adjustable suspension wires to individuallyinstall, easily clipping the lamps to theframework on each tier. The uniformity wasmade possible using accurate lasercutting for all the metalwork involved.The fitting was designed in SolidWorks3D CAD software which calculated theflat patterns of the petals. These werethen exported as 2D DXF files. Theturnaround of laser cut parts, from computerto delivery, was about seven days: thisstreamlined our manufacturingprocess, enabling us to be ableto meet the ambitious threeweek lead time. Using mainsdimmable LED lamps in thefittings, Northern Lights alsosupplied an energy efficient solution tolight a large area, with each fitting onlyrequiring 45 watts of energy.

We also supplied a 3m diameterfeature pendant for the Foyerarea, to create a spectacularwelcoming centrepiece thatmirrors the graphic in the floortiles. This was still a Lotusflower pendant but of acompletely different geometricstyle. The whole buildingfeatures details of typicaltemple architecture fromNorthern India and these fittingsfit within the scheme perfectly.This is just another example ofhow Northern Lights' designersselect bespoke elements withina scheme and design lightfittings to complement yourcreativity.

The world of lighting will never be thesame again. It is moving and movingfast!. It is turning a sleepy country laneinto an ultra fast express highway.Creating light is something we, at Philipshave done for many years and, creatinglight with LED is something that excitesus enormously. There are so many morepossibilities with LED lighting, but equallyas many challenges. Despite thesechallenges, we truly believe LED lightingis now ready to be used effectively inalmost all lighting applications, varyingfrom accent lighting in a retailenvironment to office lighting at higherefficiencies than fluorescent lighting.Street lighting is also taking advantageby turning yellowish outdoor lighting intowhite LED light and creating saferenvironments. The small size of LEDsalso allows for multiple interestingdecorative LED lighting applications inthe home and hospitality environments.LED is really here to stay and is alreadydelivering breakthroughs in regularlighting applications.

What is currently still unthinkable forcurrent lighting applications Philips willsoon be making reality.The Philips Fortimo LED portfolio isalready today, and will also be tomorrow,the LED module range for an extensivevariety of applications.The Fortimo system is based on fivebuilding blocks to ensure the highestquality products that will deliver the bestquality of white light now and into thefurture whatever your application:

The central promise of the Philips Fortimo LED product range is constant innovation within a fixed format and includes both a standardised optical interface and lumen package. As long as this defined format is used, luminaire manufacturers can easily implement the latest advances in LED efficacy, without having to change the driver, the dimensions or the LED module or the lumen output. It also means that Philips can provide constant innovation.

The Fortimo LED spotlight module Gen 2 features upgrades to the entire product portfolio:

Performance upgrade: Greater efficacy increases lumen output by up to 30% plus better SDCM.

Portfolio Expansion: New CRI 90 module and addition colour temperatures now available.

New Optical Dome: Gives improved homogeneity, with no ring pattern and only 3% light loss.

Cooling Costs: New casings give better cooling thus giving upto a 40% saving on cooling costs.

The Ideal Alternative: These enhancements make the Fortimo LED SLM range the ideal solution for retail

IntelligentSwitching

Being pro-active to minimise the impact of therapidly rising cost of energy is vital for allbusinesses. Reducing building maintenance costscan also produce substantial savings. LeopardSwitchLite and Leopard LED are two new productsfrom Thorn Lighting that can achieve both of thesewhen compared to standard 2D fluorescentbulkheads.

In most commercial buildings, there are often manylocations where lighting is left on all day every dayregardless of whether or not it is needed. Runningcost savings of 60%, 70% or even greater than 80%are possible by using automatic switching withlighting in areas that are infrequently occupied suchas store rooms, toilets, corridors, stairwells andmeeting rooms.

Energy management using ‘intelligent’ switchingtechnologies is one of the prime methods that isincreasingly being employed to combat the risingcost of energy and Thorn Lighting’s new SwitchLiteLeopard Bulkhead employs a microwave sensor todetect movement ensuring that luminaires are onlyswitched on when needed.

The cost of building maintenance can be verysignificant both in terms of finance and inconvenience.Having to close off areas of a building to the generalpublic to replace or repair lighting or even just tochange lamps can be very disruptive. Similarly,employing someone to do it frequently can prove veryexpensive.

LED lamp technology means instant light, reducedenergy consumption, greater efficiency and veryimportantly, massively increased lamp life.

Using the Leopard LED bulkhead 8 hours per day, 7days a week, you’re unlikely to need to change thelamp for the next 17 years and even using it 24/7 itwill still be almost 6 years before you need to considerlamp changes in most cases. Add to that the fact thatLED technology produces whiter light with a full lightoutput from the start and can be used efficiently inenvironments with much lower temperatures such ascold stores, it means that compared to moretraditional fluorescent lamp technology, LED scoreshigh on all counts.

Everyone loves fabric shades! They come in allshapes and sizes and in virtually any material -silk, cotton, suede, leather and prints.

A fabric shade can fill any space matching anyinterior or other design features. It is a very cost-effective alternative to the more traditional styleof pendant.

We first started making fabric shades about sixyears ago. This came about as a result of our not

being able to source large fabric shades robustenough to withstand the rigours of the contractmarket

Initally we were making shades typically from800mm to 1.2m in diameter. However, as timewent by the demand for ever larger shadesincreased. To date the largest shade we haveactually made was for the Ann Summers flagshipstore in the Westfield Shopping Centre atStratford. This measured 3.5m in diameter by1.5m high.

Six years down the line our factory nowincorporates a fully equipped departmentspecifically for the manufacture of fabric shades.

The process of making a fabric shade starts withinput from the designer. It could be anything froma simple drum shade to a complex tiered shape.From the design we produce the metal frameworkwhich is a very important part of the process.Formerly smaller fabric shades were made usingthin wire for the frame. However, as shadesincrease in size this method of creating the frameis no longer appropriate. Large shades requireheavier gauge materials and careful design tomaintain the structural integrity of the frame.Once the frame is complete it is powdercoated in acolour appropiate to the final design.

Lighting in a material world...Using bespoke fabric shades

enlightened 21

Meanwhile the required fabric is sourced andbacked with PVC. Another small section of thefabric is turned into trim for the edges of theshade. Once the fabric and the trim are ready inthe workshop they are prepared and cutaccordingly and are then applied to the framesby hand.

The whole process may sound straightforward.but it has taken us years of innovation to get towhere we are now. We have had to work out howto build larger and more elaborate yet lighterframes. A great deal of research and developmenthas gone in to powdercoat finishes, adhesivesand fabrics. The finished shade also has to be litand with a larger shade considerable thought hasto be given as to how this will be achieved. Theillumination of the shade is crucial to the overallfinished effect. This is to ensure that the endproduct will not only be an aesthetically pleasingpiece of work, but will also be structurally soundand fit for purpose.

If you have a requirement for bespoke fabricshades regardless of size, colour or quantityplease contact our Sales Office.

After powdercoating the frame isassembled to check that it fitstogether and that all thedimensions are correct.

Working together with Street Eite Design Associates weproduced these cocoon shaped pendants using a woodveneer with a red acrylic lining. Each individual shade isset at an angle to the next one creating visual interest.

A smaller version of this pendant was also shown on ourstand at The Sleep Event and was very well received.We have even been asked to look at designing a walllight version to match the pendant.

A sample range of coloursfrom the Indian Douppion SilkRange from our specialist silksupplier Pongees.

Colours and materials...The majority of our fabric shades arefinished in the finest Indian DouppionSilk or the highest quality cotton. Our range includes most colours, the majority of which are readily available.We have produced shades in many materials - from cloths, wool, yarns toparchment, vinyl PVC and even wallpaper!. Most of these materialscome in standard colour ranges and can even be specially printed to suit aspecific colour or image that you needto match.Points to consider when choosing materials and colours:

Darker and thicker materials allow lesslight to diffuse through the shade.

The use of reflective materials on the inside of shades may affect the light.

Lighter, thinner materials will allowmore light to pass through, it may alsomake frame shadows more prominent.

Bold patterns and stripes usually workbetter on straight sided shades.

On large scale shades the fabric willneed to be sectioned or joined if the shade is wider than the fabricwidth.

Light output can also be altered withthe use of diffusers to the top and bottom faces of the shade.

The fabric is applied by hand to eachsection of the frame. In this pictureone of our staff is fixing the vividpink lining fabric to the inner side ofthe frame

Fabric application:A diamante band is fitted allaround the bottom edge of theshade to add a bit of sparkle.

Lamp lumens means the sum of theaverage initial (100 hour) lumen output ofall the lamps in the luminaire.

Circuit-watt is the power consumed inlighting circuits by lamps and, whereapplicable, their associated control gear(including transformers and drivers) andpower factor correction equipment.

Lamp lumens per circuit-watt is the totallamp lumens summed for all luminaires inthe relevant areas of the building, divided bythe total circuit-watts for all the luminaires.

LOR is the light output ratio of theluminaire, which means the ratio of thetotal light output of the luminaire understated practical conditions to that of thelamp or lamps contained in the luminaireunder reference conditions.

Luminaire lumens per circuit-watt is the(lamp lumens x LOR) summed for allluminaires in the relevant areas of thebuilding, divided by the total circuit-wattsfor all the luminaires.

The Sleep EventThe Northern Lights team put in a real effort this year tocreate a stand which would highlight our unique client-ledservice. We wanted to show off not just our standardproduct range (although nothing we ever do is 'standard'!),but the endless possibilities of everything we can offer interms of custom-made fittings. All fittings weremanufactured at our factory in Chesterfield. The collectionwas based on the concept of showcasing a wide range ofmaterials and finishes, styles and types to spark theimagination.

Our hard work definitely paid off. Our stand was very wellreceived by the visiting delegates. Our sales team made alot of interesting new contacts with potential clients. Withsuch a variety of materials and finishes to show off, fromcomplex bespoke pendants to simple bedroom suites, wehad plenty to talk about over the two days of the event.

We also had a strong theme of new LED technology runningthrough the stand this time, as a result of our partnershipwith Philips. Each and every fitting was powered by aPhilips LED lamp and we had a whole section on the standdedicated to colour-changing LED modules which werecontrolled by Philips 'to-be' touched lighting controls. Thisaward-winning intuitive system has to be seen to bebelieved. Select any colour or white range from thespectrum and the LEDs change instantly to your choice. Itcan even be programmed to cyclethrough your favourite colours!

The Northern Lights design team canengineer this technology into virtually any of your concepts, bringing yourdesign to life. It also goes without sayingthat this technology is energy-efficient. It has a very long lamp life, which helps to make long-term cost savings andmeets energy efficiency regulations.

Utilising the accuracy of laser cutting, thesestandard and table lamps offer a unique designavailable in a wide range of powdercoat andspayed finishes. The oval shape used in thesefittings can be changed to any shape you wantand the spacings can also be modified tocreate the desired look.
