It's a Trade-Off Higher-end shops do

not need to use more

energy to be effective.

The lighting layouts on

pages 4, 5 and 6 all

have connected loads

of 2.1 watts per square

foot or less. All achieve

good quality lighting

appropriate for their

businesses. Higher light

levels are provided in

Basic retailing. Higher-end

shops provide more

focus and highlights bydecreasing the ambient

light levels. Compared

to common practice,

2.1 watts per square

foot not only meets

the latest energy codes,

but also saves 30% of

a store's energy cost

for lighting.


3/8

don’ts

1. Put the light source closeto the merchandise.

2. For ambient lighting, use

efficient, diffuse sources,such as fluorescent.

3. For accent lighting, usenarrow beam spotlightssuch as Halogen PARs orLow-Voltage MR-16s.

4. Use the fewest typesof lamp to get thedesired effect,reducingrelamping

mistakes andmaintenanceheadaches.

5. Illuminate the aisleswith spill light from theaccented merchandisingareas or displays.

6. Lower levels of ambientlighting require fewerwatts of accent lighting.

7. Use the lightest colorson the interior surfacesof shelving.

8. Use organized patternsof light fixtures. Chaotic

patterns may confuse,agitate or fatiguethe customers.

9. Use high color renderinglamps for both ambientand task lighting.

TRUE OR FALSE?

Q. Incandescent light has a truer color?

A. FALSE. There i s no “ t ru e” color of l ight , but m id-day natu ral l ight i s often considered a s tanda rdbecause i t has a l l the wavelength s of color in m ore or less equal am oun ts. Inca ndescent sources are

rich in warm tones but weak in cool tones. This i s fla t tering to skin ton es but poor in reveal ing colors

for ma ny products , especial ly those contain in g b lues an d greens. New “t ri -phosphor” technology has

resul ted in f luorescent sources with su perior color rendering in a wide varie ty of color appeara nces

an d l am p t yp es.

Q. Low-voltage lamps use less energy than standard voltage lamps?

A. FALSE. A 50 wat t 12-vol t lam p uses the sam e am oun t of power as a 50 wat t , 120 vol t lam p or 50 wat t

277 vol t lam p. However, low-vol tage lam ps ha ve sm al ler f ilam ents, which en ables t ighter focus of the

beam . Thu s, low vol tage m ay be the m ost energy-effect ive choice for accent l ight ing .

Q. More light is better?

A. FALSE. Light ing for re ta i l i s a l l about cont rast and focus. Too much accent l ight ing means

no cont rast and no focus. The greatest l ight ing value i s achieved by balancing ambient and

accent l ight ing .

COMMON MISAPPLICATIONS

1. Using incandescent

lights for everything

2. Track lighting rather

than fixed locations

3. Using floodlights

rather than spotlights

4. Random fixture layouts

or visual chaos

5. Too many shiny

surfaces

6. Black ceilings

7. Dark finishes

8. Accenting everything emphasing nothing in particular

9. Spotty lighting. Not enough ambient light to clearly

examine merchandise

"The first

step is to

establish

the store

lighting

categorywith the

Owner, since there will be a

tradeoff between accent

lighting and ambient light

levels. There is no single right

way to design retail lighting,

so it’s important to agree on

which lighting approach to

follow, “basic," “intermediate”

or “higher-end.”

“Proper lighting controls assurethat individual fixtures are ononly when they are mosteffective. The display windowlights should be controlled

separately from the rest of thestore lights. In addition, otherfixture types should be on separate circuits,controlled by an astronomical time clock. Thisway, only the most efficient fixtures will be usedoutside of business hours, for staff activities suchas cleaning and restocking. This not onlysaves energy, but greatly reducesmaintenance for burned-outaccent lights.“
