Industrial Lighting
Applications and considerations

Industrial Lighting - What matters most
Industrial customer concerns:
Save money
Energy savings
Maintenance savings
I need more light where I need it
This is key
More light = better productivity and safety
Agenda
• How do we perceive light: CRI - Kelvin
• Existing technology review
• LED
– What it is
– How to compare
– What is important in a fixture
What is CRI and Kelvin temperature


Kelvin Temperature: what
comes out.

Warm vs cool light

Eye sees better in blue light
CRI: what we see

Range 0-100

Measures intensity at specific
wavelengths

Based on incandescent

Imperfect scale
Existing In your facilities
• Fluorescent
– Instant on, hard to dim, lamps 4-6 years, lumen depreciation
• HID
– Long warm up, high LPW, MH 24,000 life, HPS yellow
• Solid State: LED
– Instant on, high LPW, easy to dim, OCC, minimal maintenance
LED
Components of an LED fixture
• LED : Light Emitting Diode --- Lamp
• Driver --- ballast
• Surge Protector --- drivers are not as robust as magnetic
ballasts.
– Helps suppress transients (not the same as a fuse)
• Optic – still very important
• Housing – LED fixtures still need a housing
How to compare LED for Industrial
What matters most
• Lumen output
• Watts consumed
• Energy efficiency (lumens per watt)
How to compare LED for Industrial
What matters most
LIFE – LED is a whole new ball game. This is NOT HID
– When will the lights go out?? With LED they don’t go
out (unless there is a problem)
– Driver life 100,000 hours
– Optic life- so long may need cleaning before replaced
Lamp Mortality – all traditional sources

Light Loss Factors and LED
Will it pass the test of time?
• LED Light Loss Factors LLF
–
–
–
–
LLD: Lamp Lumen Depreciation (LED L70 / TM21)
LDD: Luminaire Dirt Depreciation
BF/DF: Ballast Factor (LED Driver Factor DF = 1)
TF: Thermal Factor (** BIG DEAL IF HOT)
Traditional: Lumens Out = Lamp rated lumens * LLD * LDD * BF * TF
LED:
Lumens Out = Initial Lumens* TM21 * LDD * DF * TF
Used to predict long term performance
Fixture efficiency
• Get the lumens OUT!
• Typical office – 75-92%
• Typical highbay – 55-85%
• Typical cobra head – 50-80%

LED
Optics – Life and Performance
Customer: “I want an LED that will last 100,000 hours.”
Lets use an optic that will too.
What optics affect:
 Maintenance – does it get brown, cloudy or brittle?
 Lumen output and efficiency – careful with frosted lenses
 Glare - Prisms / Frost / Flat glass
 Does it matter if it’s glary?
 Distribution – where is light going?
 I can see the thing I am trying to look at. YAY!!
Distribution Patterns
Light where you want it
A
This is the exact same lumen fixture
Which is which?
• reflector, symmetric
• refractor, symmetric
• reflector, asymmetric

What LED has to offer
• Benefits
–
–
–
–
–
–
–
Provide strong down light – great for high mounting heights – check optics
Can be great for ‘hot’ or cold applications – check temp ratings
Can be a small surface area so it works well in dirty environments
Instant ON – no warm up needed to hit full bright.
Dimmable to 10% - additional energy savings
Long Life – 100,000+ hour lamp life / 100,000 hour driver life
Can have good lumen maintenance – maintains high lumen output over
the life of the LEDs (TM21)
Thank you!!!
