LEDPro.com LEARNING CLINIC
LEDPro.com strongly believes it is important to provide our customers with a wide range of energy efficient lighting education, to help them make the most informed lighting decisions possible.
Below you will find a list of benefits for energy efficient lighting along with some fun facts about LED Lighting and also a complete lighting glossary for your educational benefits.
Lighting History Time Line:
1879 - Edison Light Bulb
1901 - Fluorescent Tube Light
1919 - Sodium Vapor Lamp
1970s - First RED LED
1990 - “High Brightness” RED, ORANGE, YELLOW, & GREEN LEDs
1995 - “High Brightness” BLUE, GREEN LEDS
2000 - White LED Lamp
2005 - White LED Lamp demonstrates Florescent Efficiency
2014 - White LED Lamp Exceeds 100 LM/W
Current lighting technology is over 120 years old. LEDs began as just indicators, but are now poised to become the most efficient source ever created.
- LEDs are extremely energy efficient
- Area Directional – no wasted light, can run in any pattern possible
- Have a very long lifetime – between 50,000 and 300,000 hours till a 70% lumen maintenance or (L70)
- Are inherently rugged – zero filament to break
- Instant start
- Are infinitely dimmable and controllable
- Perform excellent in cold temps, no cold starting issues
- Are environmental sound with no Hg, Pb, or heavy metals
LED Potential Impact - Savings:
One teaspoon of mercury can contaminate a 20 acre lake, forever. Each year an estimated 600 million fluorescent lamps are disposed of in the U.S. landfills amounting to 30,000 pounds of mercury waist. Mercury from one fluorescent bulb can pollute 6,000 gallons of water beyond safe drinking levels.
Makeup of an LED Fixture:
- Light Engine
- Power Supply
- Heat Sink
- Optical Components
- SSL System
Reliability of the power supply and driver is the key to the lifetime estimate of an SSL system.
LED Lifetime - System Lifetime is What Creates Value
HID, Fluorescent RLL - point where 1/2of lamps burn out
LEDs don’t burn out – they get dimmer
Light Source Comparison: · T8 Fluorescent - 20K HRs
Halogen - 10K HRs
T12 Fluorescent - 20K HRs
LED T8 Tube (Best in Class) - 50K HRs
High – Pressure Sodium - 20-24K HRs
T5 Fluorescent - 20K HRs
Low Pressure Sodium - 18K HRs
LED (Best in Class) - 100K plus HRs
New LED Fixture Certification Process:
LED Chip MFG (LM80 Standards)
New Fixture Design
UL Testing (Electrical/Fire/Safety
Photometric Testing (LM79 Standards)
TM21 Estimated Lifetime
DLC QPL (Approved for Rebates)
Other (e.g., INT. (Dark Sky Assoc Approved)
Why do Utility Companies Offer Rebates?
Utility Companies set annual energy savings goals that they strive to meet. End user incentives are an energy saving alternative to the much greater capital expense of expanding power plant capacity and infrastructure maintenance. It is often cheaper to pay out rebates than it is to build a new power plant.
