  a good choice for high bay lighting
  applications?
  
• Are the Linear Fluorescent products appropriate
  for all types of high bay applications?
  
• Is Metal Halide no longer a good source for these
  types of applications?
  
• If I choose a Metal Halide fixture, what is the
  best system to choose?
  
• If I choose a Linear Fluorescent fixture, what
  are appropriate mounting heights?

Metal Halide Systems
Common Characteristics

• The small lamp/arc tube size allows for excellent
  optical fixture design
  
• Puts the light where you want it
• Good initial fixture light output
• 63 to 77 LPW for the Total Fixture System
• More lumen depreciation than fluorescent lamp
  systems
  
• Worst - standard metal halide with CWA ballast
• Slightly better - PSMH with CWA ballast
• Better - PSMH with 277v Reactor ballast
• Best - PSMH with Electronic ballast
• Limited to 50 power on Bi-level systems

7
Linear Fluorescent Systems
Common Characteristics

• The Larger Size Lamp is Harder to Control for
  Optical Design
  
• The smaller T5HO is better than the T8
• Very Good Initial Lumen Output
• 75 to 80 LPW for the total fixture system
• But, less total lumens per lamp - more
  lamps/fixture
  
• Very Low Lumen Depreciation
• Excellent mean light output throughout life
• Mean lumens are 95 of initial
• End of life lumens are 90 of initial
• Fixtures are Larger Than Those Using Metal Halide

Primary System Characteristics
Where Do I Start?

• Mean Lumens at 40 of rated life
• End-of-Life Lumens
• Most users do not maintain their lighting systems
  - therefore, the light levels are typically
  below the designed mean level.
  
• Metal Halide lamps will continue to operate past
  end of rated life at even lower output.
  
• Impact of Ambient Temperature
• Maintenance Issues
• Number of fixtures and lamps per fixture
• Cost of replacement lamps and ease of fixture
  cleaning
  
• Ballast temperature limits
• Fixtures designed with optimal thermal properties

27
Secondary Characteristics
Other Considerations

• Bi-Level Operation
• Power consumption at low setting
• Metal Halide limited to 50, Fluorescent is 0
• Ceiling Obstructions (Sprinklers or HVAC)
• Frequent Power Failures
• Number of Operating Hours
• Cleanliness of Environment
• Color Rendering
• Color Temperature
• 3000K vs 4000K

28
The Final System Choice
What is Most Important?

• Initial Installed Cost
• Fixture cost and number of fixtures
• Initial cost for project
• Annual Operating Cost
• Energy usage and cost
• Maintenance costs
• Total Cost Initial Installed Annual Operating
  Cost
  
• Impact of the Ambient Temperature Environment

29
Applications
New Installation vs. Retrofit

• New Installation Considerations
• Designed to a given mean light level
• Initial cost important
• Life cycle costs should be most important
• Retrofit Installation Considerations
• Usually swap fixtures one-for-one
• 400w MH set as benchmark
• Energy savings and rebate incentives

30
Utility Rebates
Rebates provide incentives

• Rebates help save energy and will reduce payback
  periods.
  
• Demand side management is still important.
• Many states currently have programs in place
  through utilities
  
• Alaska, California, Connecticut, Florida, Hawaii,
  Idaho, Indiana, Iowa, Maine, Massachusetts,
  Minnesota, New Hampshire, New Jersey, New York,
  Oregon, Rhode Island, South Dakota, Texas,
  Vermont, Utah, Washington among others
• Check with your local utilities to see what they
  may have available.
  

31
New Installations
Open Areas and Warehouse Aisles

• Open Areas 100,000 square foot x 25 space
• Continuous operation without Bi-level control
• One start per day
• Warehouse Aisles 10x 500x 30 space
• Excellent candidate for occupancy sensor control
  with Bi-level systems (many starts per day
  possible)
  
• MH and PSMH
• Uses approximately 50 power in low mode
• Fluorescent Systems
• Can be turned completely off when no occupancy
  sensed
  
• Uses 25 of power by leaving half the lamps on
  for every other fixture down an aisle for
  stumble light

Energy Savings Potential

• Newer lamp and ballast technologies save energy
• Local energy rebates reduce payback period
• One-for-one fixture swap
• Initial cost per fixture
• Look at big picture instead, including payback
  times
  
• Ambient temperature concerns
• Designed light levels
• 4-5 year old 400w MH CWA systems are 40-50 below
  initial light levels, and 10-20 are below
  designed light levels
  
• Linear fluorescent high bay fixtures can replace
  existing fixtures with similar designed light
  levels

Questions Answered

• Are the new Linear Fluorescent High Bay fixtures
  a good choice for high bay lighting applications?
  
  
• Yes! Especially in retrofit applications with
  controlled ambient temperatures.
  
• Are the Linear Fluorescent products appropriate
  for all types of high bay applications?
  
• Not all remember to note any ambient
  temperature issues, ceiling obstructions, optical
  distribution, and color rendering.
  
• Is Metal Halide still a good source for these
  types of applications?
  
• MH is still a good choice, especially when
  choosing PSMH systems.

61
Questions Answered

• If a Metal Halide fixture is chosen, which system
  is best?
  
• Look to PSMH, and soon the electronic ballasts
  will come down in price.
  
• If a Linear Fluorescent fixture is chosen, what
  are the appropriate mounting heights?
  
• T8 fixtures typically, 10 12 is the minimum
  recommended mounting height, and the maximum will
  be dictated by the light level you are looking
  for. If you need a high light level, you may find
  that there are too many fixtures needed to
  achieve it and a MH system may be a better choice
  for initial cost and energy usage.
• T5HO fixtures 10 minimum mounting height when
  using the prismatic and white reflectors for task
  lighting 13 with the aluminum reflector.
  Perhaps higher depending on the desired light
  level. The maximum will be dictated by the light
  level you are looking for.

62
An Idea in Closing!

• Over 40 million of the original 400w MH lamps are
  still in operation today.
  
• Factories
• Warehouses
• All of these original systems can be replaced
  with any of the newer systems that were shown
  today.
  
• Significant operating cost savings are possible.

What a Great Business Opportunity!!!!
