Bridgelux ES Array Series
Product Data Sheet
Introduction
The Bridgelux family of LED Array products delivers high performance, compact and cost-effective solid-
state lighting solutions to serve the general lighting market. These products combine the higher efficacy,
lifetime, and reliability benefits of LEDs with the light output levels of many conventional lighting sources.
The Bridgelux ES Array Series has been specified to enable lamp and luminaire designs surpassing
efficacy and quality of light requirements driven by regulatory standards with reasonable system design
margins, enabling lighting product compliance to Energy Star, Title 24, Part L and other global standards.
The Bridgelux ES Array products provide a high performance alternative to conventional solid state
solutions, delivering between 400 and 2000 lumens under application conditions in warm, neutral and
cool white color temperatures. These compact high flux density light sources deliver uniform high quality
illumination without pixilation or the multiple shadow effect caused by LED component based solutions.
To simplify system design for appropriate light output, Bridgelux LED Arrays are specified to deliver
performance under typical use conditions.
These integrated plug and play solutions reduce system complexity and enable miniaturized cost-
effective lamp and luminaire designs. Lighting system designs incorporating these LED Arrays deliver
comparable performance to that of 20-100 Watt incandescent and halogen, 7-42 Watt compact
fluorescent, and 18-50 Watt HID based luminaires and feature increased system level efficacy and
service life. Typical applications include replacement lamps, task, accent, spot, retail, track, down light,
low bay, wide area, security, wall pack and street lighting.

Product Nomenclature
The part number designation for Bridgelux LED Arrays is explained as follows:
BXRA–ABCDE–RRRRR
Where:
B X R A – designates product family
A – designates color, C for Cool White, N for Neutral White and W for Warm White
B C – designates LED Array product flux, 04 for a 400 lumen array, 08 for a 800 lumen array, 12
for a 1200 lumen array, and 20 for a 2000 lumen array
D E – designates product family
R R R R R – used to designate product options, 00000 by default
The base product part number (BXRA-ABCDE) is indicated on each individual unit, printed on the bottom
of the LED Array.
Average Lumen Maintenance Characteristics
Bridgelux projects that its family of LED Array products will deliver, on average, greater than 70% lumen
maintenance after 50,000 hours of operation at the rated forward test current. This performance
assumes constant current operation with case temperature maintained at or below 70°C. For use beyond
these typical operating conditions please consult your Bridgelux sales representative for further
assistance.
These projections are based on a combination of package test data, semiconductor chip reliability data, a
fundamental understanding of package related degradation mechanisms, and performance observed
from products installed in the field using Bridgelux die technology. Bridgelux conducts lumen
maintenance tests per LM80. Observation of design limits is required in order to achieve this projected
lumen maintenance.
Environmental Compliance
Bridgelux is committed to providing environmentally friendly products to the solid-state lighting market.
Bridgelux LED Arrays are compliant to the European Union directives on the restriction of hazardous
substances in electronic equipment, namely the RoHS directive. Bridgelux will not intentionally add the
following restricted materials to LED Array products: lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).

UL Recognition
Bridgelux product became UL Recognized on 31 March, 2010. Please refer to the UL file E333389.
Bridgelux uses UL Recognized materials with suitable flammability ratings in the LED Array to streamline
the process for customers to secure UL listing of the final luminaire product. Bridgelux recommends that
luminaires are designed with a Class 2 Driver to facilitate the UL listing process.
Minor Product Change Policy
The rigorous qualification testing on products offered by Bridgelux provides performance assurance.
Slight cosmetic changes that do not affect form, fit, or function may occur as Bridgelux continues product
optimization.
Cautionary Statements
CAUTION: CONTACT WITH OPTICAL AREA
Contact with the resin area should be avoided. Applying stress to the resin area can result in damage to
the product.
CAUTION: EYE SAFETY
Eye safety classification for the use of Bridgelux LED Arrays is contained in the CIE S 009/E2002
Photobiological Safety of Lamps and Lamp Systems specification. Bridgelux LED Arrays are classified
under section 6 lamp classification as Risk Group 2 (Moderate Risk). Please use appropriate
precautions. It is important that employees working with LEDs are trained to use them safely. Luminaire
manufacturers should refer to CIE S 009/E2002 to establish the classification of their product.
CAUTION: RISK OF BURN
Do not touch the LED Array or resin area during operation. Allow the LED Array to cool for a sufficient
period of time before handling. The LED Array may reach elevated temperatures such that it can burn
skin when touched.

Case Temperature Measurement Point
A case temperature measurement point location is included on the top surface of the Bridgelux LED
Arrays. The location of this measurement point is indicated in the mechanical dimensions section of this
data sheet.
The purpose of this measurement point is to allow the user access to a measurement point closely linked
to the true case temperature on the back surface of the LED Array. Once the LED Array is installed, it is
challenging to measure the back surface of the array, or true case temperature. Measuring the top
surface of the product can lead to inaccurate results due to the poor thermal conductivity of the top layers
of the array such as the solder mask and other materials.
Bridgelux has provided the case temperature measurement location in a manner which closely ties it to
the true case temperature of the LED Array under steady state operation. Deviations between thermal
measurements taken at the point indicated and the back of the LED Array differ by less than 1°C,
providing a robust method to testing thermal operation once the product is installed.
