Lighting is a major component of electrical energy consumption in commercial buildings.With increases in energy costs, there is a growing need for efficient, cost-effective lighting options. At this workshop, Cheryl Allen of Green Planet Lighting will display modern lighting alternatives to control operational costs and deliver more sustainable solutions.

2. More site electricity is consumed for
lighting than for any other end use.
~40 % of electrical use

3. The Opportunity
Changing sources in energy production,
electricity de-regulation, power pricing,
federal and state energy policy, available
lighting technology and business and public
cost consciousness create a ‘perfect storm’
for economically introducing enhanced
lighting solutions

6. Types of Lighting
• Standard fluorescent
– Mixture of low pressure mercury vapor and inert
gas (such as argon) in tube. Phosphor powder
coating on tube fluoresces excited by UV emitted
by mercury vapor when current applied. Current
controlled by a ballast.

7. Types of Lighting
• Down lights/track lighting
– Same technology as above
– Compact fluorescent
– Halogen
• High intensity discharge (HID)
– Mercury vapor, metal halide, and high
pressure sodium lamps

9. T8 Lamps and Ballasts T8 Lamps –
Latest Technologies
• New 2nd, 3rd & 4th Generations
• 25w, 28w, 30w & 32w versions
• Higher Lumen Output
• Better Lumen Maintenance
• Longer Life

10. T8 Electronic Ballasts
• Ballast Factor – Determines Light Output &
Wattage
• LBF-.77 ∙ NBF-.88 -.90
• HBF-1.18 -1.20
• Instant Start – Lower Wattage, not
recommended for use with occupancy
sensors
• Programmed Start – Longest Lamp Life and
Excellent Energy Savings, compatible with
sensors

14. T5HO Fixtures vs. 400w HID Fixtures
• Energy Savings – 458 Input Watts Vs. 240 Input
Watts
• Dramatic Color Improvement - Read Labels
More Accurately
• Improved Light Output - Both Horizontal &
Vertical
• Program Start Ballast Technology - Long Lamp
Life

15. T5HO Fixtures vs. 400w HID Fixtures
• Occupancy Sensors Turn Off T5 Fixtures When
Not Needed - Fixtures Turn On Instantly When
Area Is Occupied
• Low Lamp Lumen Depreciation - Increases Time
Between Relamps
• Substantial Maintenance Cost Avoidance - 5
Year Ballast & 2 Year Lamp Mfr. Warranty
