Identifying Key Criteria

Lighting trends, competitors?Light levels, reduction?Colour rendition?Colour appearance?Luminaire and Lamp positionAmbient versus Accent lighting

High Activity SpacesDiscount department stores, supermarkets.

Sales assistanceMinimal.

ProductsEasily recognisable, evaluated and decided upon.

AimsVisit store, easy to see, find and purchase quickly.

Light levels750 -100 lux

SpecificationHigh uniformity, generally store specific layout CRI 70+. T5 or Ceramic discharge with lighting control and good use of daylight.

Medium Activity SpacesGeneral department stores, convenience stores.

Sales assistanceMix of self service and some sales assistance.

ProductsEasily recognisable, evaluated and decided upon.

AimsProvide a pleasing, comfortable environment ,a space where people stay longer to shop. Display areas and key merchandised areas.

Light levels500-750 lux.

SpecificationLower uniformity, often aisle specific, CRI 80+. Recessed T5 with Ceramic discharge or LED used as accent lighting in key areas. Less use of lighting controls.

Low Activity SpacesSpecialist food and drink stores, butchers and bakers.

Sales assistanceHigh level and help from staff.

ProductsHigh quality products usually high cost.

AimsStay as long a possible, inspect or taste product. High quality retail experience.

Light levels300-500 lux.

SpecificationMinimal uniformity, CRI 85+. HIT or LED used as accent lighting only. Less use of lighting controls. Minimal daylight. Used to be the last bastion of halogen light source.

Design versus RegulationDesign versus CostDesign versus Energy

Can they all work together?

Brief:

Manufacturer of office screen systems in Yorkshire

Supply a cost effective double sided A0 LED lightbox

Low cost solution BUT

Other criteria....

Total depth 45mm each side

Was this compatible?

1. how bright does the product need to be illuminated?

Equal to the existing design which used 6 x 36W T8 lamps – enough to combat sunlight2. will efficiency and maintenance be key to ROI?

The cost of replacing lamps onsite was very expensive – hence the idea to fit with LED’s

  Amp draw Lumens Life LEDs 12.8 7,800 40,000 (at 50%) 

test results

  amp draw lumen output life LEDs 12.8 7,800 40,000 (at 50%) Fluorescent 1 20,000 40,000 (at 80%)

test results

The LEDs were not bright enough to equal the existing solution and are much less efficient than the HF ballast and cost 10 times more....???

conclusion

1. Establish a specific criteria for the result you want e.g lux level, cost, maintenance budget

2. Evaluate all options – employ someone to question the brief

3. Don’t believe the hype:

LED light box = 10 x more expensive

12 x more energy
