Advantages

Disadvantages

Fluorescent Control Market


Although multiple technologies are available,
why is fluorescent control not widely used?


Too Expensive


Too Complicated to Design


Too Cumbersome to Maintain

New Product Focus


Make fluorescent lighting control more cost
effective


Make fluorescent lighting control easy to design
by reducing interfaces and complication


Make a lighting control system that improves
maintenance.


Meet and exceed benefits of existing
technologies without the disadvantages


Make this a REALITY

Can a system that does this be simple to design?

Begin with 1...


New architecture


Building block approach


Single Fixture, Multiple, System


No power packs or interfaces


Everything wired together works
together.


Simple customization to meet different
needs.

...Scale to



Example Single Fixture/Office

2X4 Fixture

with EcoSystem Ballast

Example Single Fixture/Office


No Interfaces, Power Packs, or Controllers


(3 Lamp, T8 32Watt, 277V)


Occupant Sensor

Daylight Sensor

IR Sensor

Any 3 Wire Phase Control
or Digital Control

Class 2
Wallstation

Example Single Fixture/Office


No Interfaces, Power Packs, or Controllers

What can the designer expect


Zoning decision can be delayed, perhaps until
commissioning


Lower cost solutions to meet the client’s needs
and energy codes


No interfaces


No miswires


Once the ballast is specified, any controls can be
added/removed/reconfigured without major
redesigns

What can the contractor expect


Control wiring free of topology and polarity
issues


Commissioning done by someone either
Lutron or contractor


Less parts and pieces to install in the field.


No interfaces to co
-
ordinate


Less wiring time

What can the owner expect


Infinite flexibility of lighting


No class 1 rewiring ever


No power packs or interface boxes to
replace or “chase” around the building


Simplified maintenance through reporting


Legitimate return on investment


Productivity improvement through proper
lighting levels and individual control


No ballast failure reprogramming
