Basics of... LED Lamps
What are LEDs?
An LED is a solid state lamp (SSL) that uses light-emitting diodes (LEDs) as the source of light. LEDs use much less electricity than both incandescent and compact fluorescent lights
What are the benefits of LED lamps?
LEDs are now designed to be used for retrofit lamps in place of conventional light sources, such as incandescent, halogen and fluorescent. LEDs will provide you with increased lumens per watt, longer life, better quality and color rendering, while using less energy.
Cost-effective: LEDs are long rated in average life, reducing replacement costs. They are one of the most energy efficient light sources in the market, delivering a fast return on investment in many applications.
Energy Efficiency
| Present Wattage x Annual Operating Hours | 60 Watts 3,000 Hours |
| = 180,000 watts per year | |
| ÷ 1,000 | = 180 kWh per year |
| x kWh rate of $0.10 | = $18 per year |
| x 100 lamps per space | = $1800 annual energy cost per space |
| Estimated Lighting Costs Using a Philips® 17W EnduraLED PAR38 Lamp | |
| Present Wattage | 17 Watts |
| x Annual Operating Hours | 3,000 Hours |
| = 51,000 watts per year | |
| ÷ 1,000 | = 51 kWh per year |
| x kWh rate of $0.10 | = $5.10 per year |
| x 100 lamps per space | = $510 annual energy cost per space |
| Total Estimated Annual Savings* | = $1,290 |
*Based on 100 lamps per space operating at 3,000 hours per year
This energy saving example shows an application of 100 lamps in a space currently using a 60W halogen PAR38, operating 3,000 hours per year at a cost of $0.10 per kWh.
** Your actual savings may vary depending on the energy costs in your geographic location.
Replacing 100 halogen 60W PAR38 lamps with the 17W EnduraLED PAR38 can provide significant energy cost savings of $1,290 per year! Potential savings from the reduction in HVAC costs as a result of using a lower wattage lamp that emits less heat is an additional benefit not included in this example.
** Light output of the 17W PAR38 at 880 lumens and 3500 candela compares to the 60W Halogen PAR38 at 800 lumens and 3200 candela.
Easy to use:
LEDs now come packaged in traditional lamp shapes that match the light quality they replace. They are easy to install: just take out the old lamp and screw-in or twist-in the LED replacement.
Better for the Environment:
- Run Cool
- Produce zero UV and IR (Infrared)
- No Mercury
- Long rated average life = less waste & fewer replacements
New FTC Consumer Labels for Light Bulb Packaging
As LED technology continues to evolve, the need to provide the consumer with accurate product information increases. In order to meet this need the Federal Trade Commission (FTC) will enforce a rule, effective July 2011, requiring mandatory new labels on light bulb packages. These labels, also called Lighting Facts, apply only to medium screw-base light bulbs (encompassing LED Solid State Lighting lamps as well as Compact Fluorescents (CFLs) and Incandescent lamps). In addition, MSC has included all of the information contained on the "Lighting Facts" Labels within the spec charts of the MSC LED, Compact Fluorescent and Incandescent Big Book Catalog ads. Below is an example of a "Lighting Facts" Label.
