Agenda
• Lighting Trends
• LED as a technology
• Why choose LED over other lighting?
• Examples and strategies
Midwest Facility Masters Conference 11-8-16
LED advantages
• High Efficacy– Fixtures can achieve 25 – 150 LPW efficacies
• 5 – 10 LPW for incandescent
• Longevity– Useful life of 25,000 to >100,000 hrs
• <1,000 for incandescent
• Environmentally Friendly– No hazardous materials
• ex: mercury vapor in CFL lamps

Reasons to choose LED
• Desire to be “Green”
• Reducing energy, not financially driven
• Reducing pollution-good for the planet
• To be on the ‘Cutting Edge”
• Federal, State, Utility grants to help with “First Cost”
Midwest Facility Masters Conference 11-8-16
Why do we light a space?
To provide the correct seeing environment to properly perform your activity
Create an aesthetic, pleasing space
Provide a safe environment
NOT to save energy-lighting consumes energy!

LED’s or SSL:Light Emitting Diodes (LEDs) are solid-state
semiconductor devices that convert electrical energy directly into visible light
Heart of an LED is composed of combinations of these elements, often called a “die” or “chip”
Actual junction of the elements is called the “P/N junction”
Midwest Facility Masters Conference 11-8-16
Where is LED lighting headed?
• Current products are at 80-205 LPW-depending on category• “Everyone” is making LED products-pick vendors wisely!• Strong emphasis on increasing efficiency – Cree has 305 LPW in
the lab• Many good point source products• Industry push to replace general lighting products- most
product improvement is evolving here• LightFair International has >500 manufacturers - all but a
handful display LED products• DLC (Design Lights Consortium) MA-Clearing House for rebates
– Summer of 2016 177,000 LED products 9,403 TLED bulbs listed– October of 2016 232,709 LED products 12,893 TLED bulbs listed

Critical issue with LED Performance-Heat dissipation
• LED’s produce heat into circuit board
• Heat management and removal is critical to proper performance and life ratings
• 50,000 hr. rating in laboratory setting-may be considerably shorter if heat is not addressed
• LED’s work better, in colder ambient temps.
• Proper fixture design must address heat removal
• Be careful of new product with 5 or 10 year warranties from 2 year old companies!
Midwest Facility Masters Conference 11-8-16
Make sure you select the
right equipment for the right application!

Retrofit:Incandescent Sockets
– For highlighting artwork or merchandise
– Auditoriums and Atriums– Retrofit with directional LED
bulbs - R, BR, PAR or MR-bulbs
– Or, consider LED track heads– Select wattages and beam
spreads that provide the needed light on “target”

Retrofit: ReflectorsFluorescent kits available
■ Example: 2x2 w/2, U-tubes to 2 or 3, 17-w T8 tubes
Improve troffer efficiency
Relocate tubes for max performance
Perform trial installation
Evaluate cost of retrofit fixtures versus replacement
- Alternative could be LED panels or retro kits
Retrofit or Redesign?• Evaluate the quality and appropriateness of the existing lighting
system.– A retrofit may replace lamps, ballasts, or fixtures but must not drastically
change the overall lighting function.
– A redesign will involve a whole new lighting system, often with quite different components and performance characteristics than the original.
• The cost of a lighting system improvement is often proportional to its permanence!

Replace Metal Halide Fixtures with HB Fluorescent/LED
• Gyms, warehouses, manufacturing
• High-Bay fluorescent-now LED
• Typical: 400-w MH to 6-L “Super” T8 or 4-L T5HO, shifting to LED solutions-Sometimes! What is your decision based on? Payback?
• About 50% savings, but determine footcandles needed!
• More with controls-programmable
Can turn off & back on with no delay-dimmable
Fixture mounted PIR sensors
SSL Troffers: A Better Option?
• Higher-quality, higher efficiency, similar-cost to retrofit kits or LED tubes
• Classrooms, Libraries, Offices, Hallways• Potential advantages of SSL fixtures

Midwest Facility Masters Conference 11-8-16
Outdoor Lighting
• Use appropriate light sources. Consider ‘white’ light, especially in low-illuminance conditions or for aesthetic appearance.
• Put light only where needed. Avoid light pollution (lighting up the sky), and light trespass (lighting neighbors’ property).
• Avoid glare from floodlights, wallpacks, dusk-to-dawn units and bright post-top units.
• Use automatic controls. All off or half off after midnight, for example. All off during daylight hours.
• Good application for wireless controls.

Controls
Midwest Facility Masters Conference 11-8-16
Why Use Controls?
• Energy and cost savings (35 – 50%)
Reduce time lighting systems on (hrs-of-use)
Dim so no more light than necessary produced (reduce power - kW)
• Code RequirementsState and Federal control mandates
• ProductivityWhen building occupants control their lighting, they are more productive
• Lighting qualityMatch ‘appropriate’ light level to task
Increase visual comfort
• SecurityAutomatic switching or occupancy sensing

Lighting Control Strategies
• Switching (manual or automatic)
• Scheduling (lights off when not needed)
• Tuning (ensures right qty. of light at the task)
• Daylight Harvesting (responds to changing conditions)
• Lumen Maintenance (compensates for depreciation)
• Demand Limiting (sheds or dims lighting at peak times)
• Demand Response (utility requests to shed load or automatic)
Midwest Facility Masters Conference 11-8-16
Tier 1: Occupancy Sensor Controls
• Occupancy sensors can save 25%-80% or more in energy costs.
• Infrared/Ultrasonic/Dual Technology/Microphonic
• Dimming/Daylighting controls can reduce energy costs and extend lamp life.
• Use ballasts appropriate for switching to maintain rated lamp life!
• Wireless controls by several Mfg.
Midwest Facility Masters Conference 11-8-16
Occupancy Sensor Types
• Infrared (PIR)
• Ultrasonic
• Sound Activated
• Dual Technology
infrared + ultrasonic
infrared + sound activated
occupancy sensor + daylight inhibit

Occupancy Sensor: Application Savings
Midwest Facility Masters Conference 11-8-16
Tier 2: Why dim LEDs?
• Dimming LEDs saves energy– 50% dimming = 50% energy savings
– Added savings to an already efficient source
• Dimming lowers operating temperatures– Extends component life (electronics & phosphor)
– Double or triple lumen maintenance
• General dimming benefits– Enhance ambiance
– Space flexibility
– Improve safety
– Increased productivity
Midwest Facility Masters Conference 11-8-16
Dimming Performance-Potential LED aesthetic issues:
– Flicker - The unexpected modulation of light level that is perceptible to the human eye (not always visually seen!)
– Pop-on - The level the light is at when it is turned off is the level it should return to when it is turned back on
– Drop-out - The light should only turn off when the switch is turned off.
– Dead-travel - Adjusting the control without a corresponding change in light level
– Audible Noise - From control or lamp
– Popcorn - Multiple lamps on the same control turn on at different times Midwest Facility Masters Conference 11-8-16

Tier 3: Wireless Occupancy Sensors & Relays
• Ceiling mounted PIR occupancy sensors that communicate with wall-box unit (or wireless relays) using RF
• Requires NO hard-wiredelectricity
• Ideal for retrofit applications
• Some units use long-life battery• Ideal for dimming applications
• Others use no battery• PV cells in sensor keep capacitor charged
• Relays operated by RF from sensors
Midwest Facility Masters Conference 11-8-16
Wireless Sensor Advantages
• Competitive cost to wired sensors
• Same or better coverage patterns
• 1/3 or less labor for installation
• Perfect for hard ceilings and inaccessible areas
• Can be integrated into more comprehensive building-wide energy management controls
• Extremely flexible, to “build as you go”
