Are incentives available? Per kWh reduced?
Any additional criteria?
How are they structured?
Custom vs. Prescriptive
Fixture-based?
Controls-based?
Any additional incentives availablefor integrated controls?
EPAct credit?
Note: You MUST do do tax and
incentive work before beginning a
project

4C. LED Lifetimes
Key terminology LM-79 Testing of complete luminaire to assess flux, power, efficacy &
color
LM-80 Approved method for measuring lumen maintenance (lifetime) inLEDs
6,000-hour tests at 3 different temperatures (55 C, 85 C and a manufacturer-selected temperature)
TM-21 IES guideline that stipulates lifetime claim at 6x tested lifetime
Temperature at which the LEDs are tested has a materialimpact on the reported results

4D. Quality & Certifications
25
Make sure any solution youre evaluating carries all requisiteindustry approvals and listings on the entire fixture
Be sure to handle the fixtures to assess quality
Some fixtures suffer from serious quality issues
Low-cost design results in environmental andquality tradeoffs
Design tradeoffs translate to higher systemtemperatures and shorter life

4E. Why Do Controls Matter? Because Plain LEDs Only Offer Wattage Savings
27
LEDs are inherently controllable Failure to control them is a missed opportunity to maximize
performance and savings
Integrated controls
Offer up to 40% additional energy savings Variables include facility use (distribution center vs.
manufacturing facility)
Cost-comparable, improve performance, flexibility, andproject economics
Manage lighting according to what is going on in the facility(occupancy, daylight, time of day)
Utility incentives often higher with controls, especiallysophisticated/integrated controls

4E. Thoughts About Add-On Controls:Lots of Devils in the Details
Adding to circuits vs. to individual fixtures
Reduces potential energy efficiency
Creates performance issues (lights are on when they dontneed to be off, or are off when they should be on)
Lack ability to change
Limited timeout settings
Sensor quality
Sensor mounting height
Third party control software
Warranty issues: Who are you going to call?
Fixture issue?
Sensor issue?
Software issue?
Installation issue?

4F. Flexibility:Why it Matters
Your needs will change. Guaranteed. Light level requirements, shifts, lighting zones, etc.
If your system supports changes, you can maximizeefficiency over time and minimize drift
Flexibility considerations
Adjustable light placement
Optics options for various environments
Remotely modify occupancy sensor timeouts, active levels,inactive levels
Scheduling change how you use your facility
Insight into how youre using your facility as a feedbackmechanism for easily accommodated change

Understand what is included in the proposal price Everything?
A la carte: Hanging hardware, Cordage, Wiring, Sensors
Are proposals based on the same assumptions?
Comparable fixture types Comparable layouts
Comparable optics
Comparable delivered light
Based on actual facility data, what are the expected costs
for your facility? Lighting solution
Annual energy costs
Expected maintenance
