ENERGY STAR® Quality Assurance
Testing Program for Residential Light Fixtures (QA4)

Program History

In October 2005, the US Environmental Protection Agency
(EPA) launched a new quality assurance testing initiative
called "QA4" under Version 4.0 of the ENERGY STAR
specification for residential light fixtures. The purpose of
this initiative is to ensure consumers continue to receive
superior quality and energy efficient performance from
ENERGY STAR labeled lighting products. Manufacturer
requirements concerning QA4 have been included in the
latest specification, ENERGY STAR Program
Requirements for Residential Light Fixtures: Version 4.1.

How QA4 Works

EPA selects ENERGY STAR qualified residential lighting
fixtures each year to undergo quality assurance testing.
Any ENERGY STAR qualified fixture or GU24 based
integrated lamp is eligible to be tested. In addition, lamp-
and-ballast platforms used in ENERGY STAR qualified
fixtures are also eligible for testing. Product candidates
are selected by utilities, energy efficiency program
sponsors and EPA based on market uptake, installer
experiences and consumer feedback. Additional
nominations may be submitted by retailers, designers,
homebuilders, manufacturers, or other industry
stakeholders. In order to limit the burden on
manufacturers, EPA selects no more than two products for
testing from each manufacturer in a given year.

QA4 Testing Process

Testing Parameters

All quality assurance testing is done by a third-party
laboratory. The laboratory purchases samples through
retail channels or manufacturer-direct if unavailable through
retail distribution. The parameters tested for each fixture
include:

Performance Parameters

•	Efficacy

•	Lamp start time

•	Correlated Color Temperature (CCT)

•	Color Rendering Index (CRI)

•	Lamp base type

•	Lumen Maintenance (1000 and 4000 hours)

•	Maximum ballast operating case temperature

Informational Parameters

•	Product packaging

•	Lamp labeling information

Detailed information on these parameters can be found in
the ENERGY STAR residential iight fixture specification,
version 4.1.

Results

Passing Test(s):

if a product passes all tests, no further steps are taken; the
manufacturer Partner has ensured that consumers are
purchasing a product with the energy savings and quality
performance expected from an ENERGY STAR qualified
product.

Failing Test(s):

if a product fails to meet the requirements of any of the test
parameters, the product is delisted within 30 days for a
minimum of six (6) months. The manufacturer Partner
must stop labeling the product as ENERGY STAR qualified.
Once the problem has been corrected, it can be submitted
for requalification with ENERGY STAR.
