Agenda Market Needs Existing Technologies in Fluorescents System Introduction Sample Applications Sample Programming Conclusion

What do you need from light control on your project?

Market Needs (End User) Energy Savings • Simplify Maintenance Greater Flexibility • LEED/Energy Codes

Current Control Strategies DALI is not a complete solution.

Existing Control Technologies 0-10V 2-Wire Phase Control 3-Wire Phase Control DALI (One type of Digital Ballast)

Anatomy of a Ballast Front End Back End Listens for signals from 0-10V, 2-Wire, 3-Wire, or DALI Controls the lamps

0-10V Technology Advantages Disadvantages 4 wire Advantages Disadvantages Mis-wire can destroy ballast or all ballasts on that circuit 2 Control Wires Code limitations Sensitive to wire length and control noise Long history Zones can be wired independent of circuits Full line voltage available to strike lamps Easy to retrofit Low cost controls THD <10% ADVANTAGES Easy to retrofit because the control wires do not have to follow circuiting. Circuits and zones can be separate. Because low voltage wire is used the zones are relatively easy to re-configure. Most codes do not require low voltage wires to run through conduit. A variety of simple, direct controls are manufactured. Good power quality and low THD of less than 10% Full voltage to ballast helps means lamps strike at any setting. DISADVANTAGES Ballast can be destroyed by mis-wires, in fact every ballast on the same zone can be destroyed if line voltage is wired to the low voltage control wire. Line voltage and low voltage wires lend themselves open for many different interruptions in the electrical code. Control wire length is an issue due to voltage drop as the wire is extended.

2 Wire Phase Control Advantages Disadvantages Easy retrofit Low cost controls No control wires THD/THC over 30% No wiring of zones independent of circuits Current implementations have lamp stability problems ADVANTAGES Easy retrofit for one 1 circuit with small load. No control wires- dimming occurs on existing two wires. DISADVANTAGES Limited voltage: Since dimming is achieved by reducing the input voltage to the ballast and not by a control signal, the voltage is reduced thereby limiting the voltage to strike the lamps. This technology also results in high THD. May require dedicated controls. May not be able to use standard incandescent dimmer because low end trim and circuitry may not be compatible. Should consult manufacturer for compatibility.

3 Wire Phase Control Advantages Disadvantages Long history Full line voltage available to strike lamps THD <10% Low control power Low cost controls Wide variety of controls available No wiring of zones independent of circuits Higher cost Extra line voltage wire for control ADVANTAGES 23 years of market acceptance The best power quality means the least amount of harmonic distortion i.e. less than 10%. Low control power signal means many ballasts can be controlled by a single inexpensive wall box dimmer.

Digital (DALI, DSI) Advantages Disadvantages 4 wire Advantages Disadvantages Every fixture is addressable Can Be Retrofitted Re-zoning capabilities Individual Fixture Control Standard Power wiring Polarity and Topology free Requires Commissioning Limited Manufacturers Limited lamp types No control protocol defined Failed ballast require re-commissioning ADVANTAGES Easy to retrofit because the control wires do not have to follow circuiting. Circuits and zones can be separate. Because low voltage wire is used the zones are relatively easy to re-configure. Most codes do not require low voltage vires to run through conduit. A variety of simple, direct controls are manufactured. Good power quality and low THD of less than 10% Full voltage to ballast means means lamps can strike at any setting and compensate for line noise. DISADVANTAGES Ballast can be destroyed by mis-wires, in fact every ballast on the same zone can be destroyed if line voltage is wired to the low voltage control wire. Line voltage and low voltage wires lend themselves open for many different interruptions in the electrical code. Control wire length is an issue due to voltage drop as the wire is extended.

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... ...Scale to 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 with EcoSystem Ballast 2X4 Fixture

Example Single Fixture/Office No Interfaces, Power Packs, or Controllers (3 Lamp, T8 32Watt, 277V) Occupant Sensor Class 2 Wallstation IR Sensor Any 3 Wire Phase Control or Digital Control Daylight Sensor

Example Single Fixture/Office No Interfaces, Power Packs, or Controllers (Other lamp types) Occupant Sensor Class 2 Wallstation IR Sensor Daylight Sensor

Beyond 1 Fixture... Traditional systems have upstream controls that make decisions.

Infinite flexibility with Class 2 sensors Add personal control at any time Add daylighting when desired Easily add more occupant sensors All load types available in future Averaging between 35%-60% of traditional system costs for classroom and office environments

Design Trends Office Buildings- Classrooms LEED, ASHRAE, Title 24 Measurement & Verification (DMW) Simplify repurposing Re-use fixtures with easy retrofit Use recessed fixtures instead of pendants to reduce interstitial space.

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 Class 2 is not enough at 277V Traditional low voltage devices are likely lower cost than these DALI devices will be.

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 Class 2 is not enough at 277V Traditional low voltage devices are likely lower cost than these DALI devices will be.
