In this presentation, we will investigate the specification of LED luminaires and ways to communicate design intent through initial concern to construction administration. We will cover how much information is necessary in specs and drawings to facilitate accurate bids and installation, reduce RFI's and maintain design integrity. We will also cover areas of concern where coordination is paramount to a successful project.
ABSTRACT
• Apply specific documenting techniques of LED systems to assist with bidding and construction administration.
• Interpret warranty information to improve owner understanding and advocacy.
• Plan for a specific controls outcome through coordination with design team, manufacturers, and owners.
• Evaluate alternate LED luminaires with specific attention to coordinating compatibility with controls and design.
• Identify potential installation & commissioning pitfalls and steps to overcome them during the design phase.
OUTLINE
IF…The drawings clearly note project controls and design
intent
THEN… I can prove how my LED system should work together
So this should be easy, right?

Document the luminaires you intend to use
• Compatibility with control systems – manufacturer’s approval • Design intent met with luminaire differences (beyond
qualities of light):• Dimensions• Remote vs. integral• Ambient temperature rating
• Warranty review for alternates

Document your dimming strategy
• List your dimming technology & type• Document common denominators in your sequence of
operations• Include driver types for all luminaires• Dimming requirements should go in your schedule
Clearly indicate dimming type
List dimming intent
If 1% isn’t required: • Consider waiting to verify dimming curves.• Put the responsibility in the contract documents to verify
after the project has bid.

Document through the Contract Drawings
• Remote and integral drivers notated on plans• Ventilation, max distances, dimensions
• Consider a separate luminaire type designation for dimmable luminaires
Sequence of Operations
• Easier for owner to read and understand• Function is for end users, not engineers• Notes should include all assumptions and outcomes in
detail• Focus on If/THEN statements
Vital information is not buried in a schedule.
Sequences can be read and understood by your owner.

Documentation is critical to make the Construction Administration process successful
luminaires selectedduring conceptualdesign.
luminaires reselectedduring final design.
luminaires ordered and installed.
Are my luminaire selections still valid?
1. Lumen outputs change rapidly2. Optics change3. Model numbers get updated4. Wattage or VA values will change5. Driver technology will innovate
Pay attention to the minutiae:• Check new bins/tolerances• Did your drivers or chip manufacturer change? • What about phosphor? Did you have chip on
board? Remote Phosphor?
Clearly identify in your luminaire schedule what is important to you.
• List details of everything
DOCUMENT
Consider the application. • Is remote a necessity? • Is there a temperature controlled driver location?
Conversely, did you spec an integral driver because there was no place to mount it?
Coordinate your drawings across your basis of design.
If driver changes (remote vs. integral) during CA: • Require contractor to suggest an applicable driver location• Ask manufacturer for voltage drop and wire size chart• Verify ventilation and ambient temperatures• Verify aesthetics with architect• Verify driver quantity for field-cuttable luminaires

Warranty fine print is rarely conveyed to the owner. They could violate their warranty without the correct information.
Seriously, would you read this?
