A REVIEW OF CURRENT LED INTERIOR & EXTERIOR LIGHTING APPLICATIONS

WHY LOOK AT LIGHTING RETROFITS?

 Improved Environmental Comfort: Lighting retrofits provide improved lighting for workplace staff

“Proper light levels improved the concentration and test scores of the students”

• Wesselowski, Schulte-Markwart, 2010

 Best Payback/Savings: Lighting typically provides the best return on investment/payback

• Interior Lighting Retrofits (Non-LED): 3-6 year payback
• Exterior Lighting Retrofits (LED):

5-9 year payback

 LED Solutions Represent the 3rd Wave of Lighting Retrofits

• T12 to T8 32W
• T8 32W to Low Watt T8 (28W/25W), LBF Ballasts

IDENTIFYING OPPORTUNITIES

(4)+ years since construction or last lighting upgrade

– Presence of T-12 or T-8 32 watt lamps (typical design of newer buildings)

– Re-lamp /Re-ballast (Utilizing 25 or 28 watt lamps / LBF ballasts) – De-lamp fixtures (retrofits) 4-lamps to 2-lamps / 3-lamps to 2-lamps / 4-lamps to 3-lamps

HID Lighting

– Gymnasiums, Shop Areas, Labs, Can Fixtures, etc.

Typical design of newer buildings

– Parking Lots, Wall Packs, Exterior Canopy and Walkways, etc.

Typical design of newer buildings

Absence of Occupancy Sensors or Presence of Incandescent EXIT Signs

RECENT TRENDS: LED LIGHTING

• Quality

Improvements

 Market Leaders – Cree, Lithonia, Sylvania, GE

Chips/Drivers – Cree, Nichea, LG, Sylvania, Samsung

 Improved light output and “spread” – especially exterior  Increased Life Expectancy (70,000 – 100,000 hours)

Compared to 20,000 hours for metal halide

• More Energy

Efficient

 Improved Efficacy (i.e. more light with less energy)

455 watt parking lot head = 131 watt LED 270 watt parking lot head = 45 watt LED

• Ex. Lithonia D-Series

92-119LPW depending on drive current, Kelvin, & Distribution

RECENT TRENDS: LED LIGHTING EXTERIOR SOLUTIONS

• Cost-Effectiveness Achieved
• Wide Ranging Distribution Types

& Performance Packages

Available optical distributions

• available. (DSX Area

LED)

Optical Distributions are Key to:

• High Performance
• Reduced Costs (wattage/fixture & # of fixtures)

Tailor fit the design for reduced Costs, Energy and Carbon Footprint! Key* Reduce hot spots and spread as evenly as possible. It all comes down to average foot candles.

RECENT TRENDS: LED LIGHTING

INTERIOR SOLUTIONS

• Cost-Effectiveness Barrier
• Numerous retrofit solution strategies
• Linear Lamp Retrofit Solutions
• Utilizes fluorescent performance characteristics
• Internal ballasted LED tube
• requires disconnect of existing fluorescent ballast
• External ballasted LED tube
• requires disconnect of existing fluorescent ballast and install
• f new driver/ballast for LED tubes
• “Plug-n-Play” LED tube simply uses the existing fluorescent

ballast

• Utilizes LED performance strengths
• Retrofit Panel Units

RECENT TRENDS: LED LIGHTING

INTERIOR SOLUTIONS

 Screw & Pin Base Lamp Replacements  Very Cost-Effective  Heavily incentivized by Utility Co.’s  Be Cautious  Enlarged bases due to heat sink  Install samples to ensure compatibility  Voltage availability  Dimming compatibility

UTILIZING LED STRENGTHS

 Dimming Drivers are standard  Design with an eye to:

 daylight harvesting

 Motion capture coupled w/ dimming  Utilize dimming range vs. on/off controls in areas

w/ safety concerns

 Exterior occupancy controls  Granular control & response
