The “BEST” measures for a lighting
system?
• Approximately 50% of the equation for light
levels is the lumens/watt.
• Approximately 50% is the environment those
lumens sit in.
• What are the some other factors?
– Cost
– Lamp life
– CRI/K temp
– Heat

“BEST” Lighting
• T8!!
– Lowest cost
– Great energy savings
– Flexibility
– High burn hours
– Legacy
– Yes, they still have mercury.
– Very low depreciation
Proprietary Information Of Energy 2013
LED?
• Still dealing with high cost
• Efficacy is improving almost weekly, lm/watt
continue to rise.
– Physics say it could get to 260 lm/watt, then we have
REAL energy savings.

•
Creates a legacy problem
Great for dimming.
Relatively low environmental impact.
Still dealing with BAD manufacturers and
marketers.

Effective Controls
•
•
•
•
Turn the D#$& LIGHTS OFF!
Simple occ/vacancy sensors
Use Daylight, IT’S FREE!
Dimming, comfort and personal preferences
raise costs, evaluate carefully!
• Can’t manage what you don’t measure, but
measuring and not managing is STUPID!

TRAINING
• Recent EE program test took place for K-12 in
GA.
• Program took and existing training package,
Building Operator’s Certification and applied it
to K-12.
• First reported results, 6 months
– 72% posted data
– Savings, $124,000+(spend was $30,800)
– Training PAYS for itself!
