TAKING LIGHTING TO HEART Questions?

Steve Brownback CBM 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  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

70% 100% L70 (hrs) light output Time Threshold T = 25C Hotter Cooler Required Lighting Lumen Maintenance curves define LED life. And this varies with temperature. LED Lamp Lumen Depreciation LLD L70

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) Used to predict long term performance Traditional: Lumens Out = Lamp rated lumens * LLD * LDD * BF * TF LED: Lumens Out = Initial Lumens* TM21 * LDD * DF * TF

Fixture efficiency Get the lumens OUT! Typical office – 75-92% Typical highbay – 55-85% Typical cobra head – 50-80% Traditional 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 This is the exact same lumen fixture Which is which? reflector, symmetric refractor, symmetric reflector, asymmetric Get a fixture that fits your space C B A

Vertical vs. Horizontal Footcandles

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)
