28.  The distribution of the illuminance is critical on most
well-designed projects
 What are you trying to light?
 What is the required illuminance level for the task?
 How can I meet that without wasting light?
 What is my desired visual effect?

31.  LED lifetimes are measured in L70, the time when illuminance
falls to 70% of initial illuminance (or a loss of 30%)
 L70 can be a LOOOONG time if the luminaire is well
constructed and reliable components are used in construction

34.  Initial Costs should be balanced with the Total Cost of
Ownership and a Life-Cycle Cost Benefit Analysis
 Often the more expensive luminaire may be less expensive
after energy costs, maintenance labor costs and overall quality
and warranty are considered
Basics of LED Light — Cost

35.  Point source or linear
 Small
 Instant on
 Switchable
 Dimmable
 Color tunable
 Color changing (16.6 million colors
with proper controls)
 Creating different form factors for
designers to use (non-traditional shapes)
What LEDs Are Particularly Good At

36.  Higher lumen packages
(heat management)
 Continuous improvement
in efficacy
 Ultimate controllability with
wired and wireless controls
 Better color management
over time – eliminate color shift
What’s Coming

37. Continual Progress in the Evolution
of Technology
 Since 1962:
– Costs going down (average 20% per year)
– Efficacies going up (average of 33% per year)
– Now, higher lumen sources can replace
traditional sources

44.  Lower panel heights, 48"-54" or lower
 No binder bins
 Collaboration over panels encouraged,
as well as ―benching systems‖
 Access to windows and daylight,
private offices and conference rooms
located in the interior of the floor
 Hotelling and ―touchdown‖ spaces
may be shared among staff

58.  Designers specify
 Engineers can make the numbers work out
with layouts, point-by-points, analysis tools,
software
 But the LOOK is the designer‘s!
Tell us the look desired and the lighting rep or factory
applications department can solve most lighting problems.
