Frequently Asked Questions:

Why LED Lighting Facts?

The rapid growth of solid-state lighting has resulted in an increasing number of new products on the market for various lighting applications. While many of these products showcase the energy-savings potential and performance attributes of LED lighting, under-performing products are also appearing in the market. Such products threaten consumer adoption and could significantly delay widespread acceptance of this new technology. This occurred in the early days of CFLs, slowing market acceptance of these products.

Others in the supply chain—retailers, distributors, lighting designers and specifiers, and utilities—may also take the pledge to use products from participating manufacturers.

Why should a manufacturer take the pledge?

Taking the pledge to test products and register them for a LED Lighting Facts label establishes a manufacturer as an industry leader in support of high quality products for LED lighting. Accurate and consistent reporting of LED product performance will increase consumer satisfaction and accelerate market adoption.

What is the LED Lighting Facts label?

Manufacturers who take the pledge agree to present the LED Lighting Facts label on product packaging or in product literature. All measurements must use results from product testing in accordance with IES standard LM-79-2008, Approved Method for the Electrical and Photometric Testing of Solid-State Lighting Devices. The label reports product performance results in five areas:

  • Lumens
  • Lumens per watt (lm/W)
  • Watts at 120 VAC
  • Correlated Color Temperature (CCT)
  • Color Rendering Index (CRI)

Manufacturers also have the option of listing warranty and lumen maintenance information on the label, but this is not required.

Will the LED Lighting Facts label signal product quality to buyers?

While the label establishes a manufacturer’s commitment to disclosing product performance, the label itself is not a guarantee of quality. It provides the basis for buyer evaluation of product quality.

Which products can be labeled?

The label may appear only on LED lighting, which includes full luminaire products and retrofit kits, not packaged LED devices. LED Lamps may only have the verified peformace statement(not the full label) on product packaging.

How is manufacturer-reported performance data verified?

 Manufacturers are required to submit a copy of the IES LM-79 test report for each single product submission or at least one product in a family grouping. For more information, please see the Product Submission and Testing Requirements. For more information, please see the Verification Testing policies.

From which laboratories will LED Lighting Facts accept LM-79 test reports?

Test reports submitted to LED Lighting Facts must come from testing laboratories listed on the LED Lighting Facts Approved Testing Laboratories list. The date of testing must fall within the valid accreditation dates listed for the approved testing laboratory. Please review the specific requirements for becoming an LED Lighting Facts Approved Testing Laboratory, including recognized accreditations, for more information.

Do manufacturers that make LED lighting have to join LED Lighting Facts?

No. The program is voluntary. However, those that join send a signal to buyers that they are committed to accurate reporting of their products’ performance.

Is there any cost to participate?

Please see the What's Changing page for information on program pricing.

There’s already an ENERGY STAR® specification. Why does the industry need LED Lighting Facts?

LED Lighting Facts and ENERGY STAR were both developed to make energy-efficient purchasing decisions easier and more transparent, but the programs support LED lighting in different ways:

  • ENERGY STAR sets a minimum performance level for qualifying products and is designed to help consumers differentiate among products based on efficiency. The ENERGY STAR label can be applied only to a limited group of general illumination LED lighting products.
  • LED Lighting Facts requires essential product information be disclosed to help manufacturers and others in the supply chain validate their product performance claims. The program’s LED Lighting Facts label may be applied to any participating general illumination LED product. Both programs are voluntary, and any ENERGY STAR partner can also take the pledge.

How do I create my labels?

First you must sign the pledge and establish an account. From there, you may log on and submit products from the Manufacturer Manage Your Products page. Once your products have passed our verification process, you will be able to click the label icon next to any approved product to download a print-quality version of the label, complete with your product’s unique characteristics.

How do I update my product listing?

Manufacturers and testing labs have the option of updating the following product performance data at any time after the product is listed without being resubmitted for approval by LED Lighting Facts:

  • Listed Values for Required Metrics (must fall within the tolerances of the Tested Values)
  • Additional Performance Metrics (warranty and dimming information claims, see below)
  • Product Qualifications and Certifications (such as ENERGY STAR)
  • Product Image/Photo

For Warranty and/or Dimming Information including URLs, those updates will need to go through the Partial Submission process.(During this time the listing will stay active but the added information will not appear publicly until it has been reviewed and approved).

Upgrades to product listings that include the following changes or additions constitute a new version of a product and must be created and submitted for approval:

  • Tested Values (must correspond to the attached LM-79 report)
  • Lumen Maintenance (supporting documentation required)
  • Model Number or Brand
  • Product type (except some subcategories)

To create a new version of a product,  open up the product record and click on the "create a new version" button. New versions must be verified and approved by LED Lighting Facts. If the older version has an identical model number and is to remain on the public products list, the new version must contain an Upgrade Date in the model number to distinguish it from the older version.  If the older version of the product has a different model number, or is intended to be Archived, the new version may be submitted without an upgrade date. Any LED Lighting Facts manufacturer partner who upgrades or updates an approved product should ensure that the information on the product list is consistent with what is in the market. Please keep in mind that product status in the market place must be kept up-to-date for more information on the Annual Product Status Update please refer to the FAQ

What information do I need to collect?

You will need the measurements from your IES LM-79-2008 test report from a currently listed Approved Lab. Please see the Product Submission and Testing Requirements for full details.

Can I submit related products as a family?

Manufacturers will have the option of grouping related products by "family," with one product fully tested and verified by the program. This option will be available to manufacturers who have established a history with the LED Lighting Facts program. For more information, please see the Family Grouping policies.
