8. Identifying Key Criteria Lighting trends, competitors? Light levels, reduction? Colour rendition? Colour appearance? Luminaire and Lamp position Ambient versus Accent lighting

9. High Activity Spaces Discount department stores, supermarkets. Sales assistance Minimal. Products Easily recognisable, evaluated and decided upon. Aims Visit store, easy to see, find and purchase quickly. Light levels 750 -100 lux Specification High uniformity, generally store specific layout CRI 70+. T5 or Ceramic discharge with lighting control and good use of daylight.

10. Medium Activity Spaces General department stores, convenience stores. Sales assistance Mix of self service and some sales assistance. Products Easily recognisable, evaluated and decided upon. Aims Provide a pleasing, comfortable environment ,a space where people stay longer to shop. Display areas and key merchandised areas. Light levels 500-750 lux. Specification Lower 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.

11. Low Activity Spaces Specialist food and drink stores, butchers and bakers. Sales assistance High level and help from staff. Products High quality products usually high cost. Aims Stay as long a possible, inspect or taste product. High quality retail experience. Light levels 300-500 lux. Specification Minimal 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.

12. Design Considerations Space lighting Product lighting Design integrity Building constraints New build or refurbishment Budget Capital cost Life cycle costs Payback period

13. Regulations and Guidelines Part L2, all new builds and refurbs over 100m2 Effective use of daylight Selection of lamp types Associated control gear and pfc Luminaire efficiency Use of lighting controls

14. Regulations and Guidelines Chartered Institute of Building Service Engineer Code for Lighting SLL lighting Handbook

15. Regulations and Guidelines Carbon Trust Lamp efficiency Luminaire efficiency Control gear efficiency

16. Regulations and Guidelines Enhanced Capital Allowance Loans and Grants Carbon reduction commitment energy efficiency scheme 80% reduction in CO2 by 2050

17. Design versus Regulation Design versus Cost Design versus Energy Can they all work together?

19. Manufacturer of office screen systems in Yorkshire Supply a cost effective double sided A0 LED lightbox Brief:

20. Other criteria.... Low cost solution BUT Total depth 45mm each side Was this compatible?

21. 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 sunlight 2. 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

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

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

26. conclusion 1. Establish a specific criteria for the result you want e.glux 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
