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 RS Array Series has been specified to enable lamp and luminaire designs with
comparable performance to existing high wattage CFL and HID conventional light sources for retail,
commercial, industrial and outdoor/street lighting applications. Bridgelux Arrays are ideal for all types of
light-on-demand applications, where they can be instantaneously and smoothly dimmed up or down
without any effect on lifetime, unlike traditional CFL and HID light sources.
Bridgelux RS Array series are a high performance alternative to conventional solid state solutions,
delivering between 3,000 and 10,000 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,
enabling excellent beam control for precision lighting.
LED array solutions reduce system complexity and enable miniaturized cost-effective designs. Luminaire
designs incorporating these LED Arrays deliver system level performance comparable to 42-55 Watt CFL,
35-90 Watt low pressure sodium, 70-150 Watt high pressure sodium or 70-200 Watt metal halide based
luminaires and feature increased system level and service life. Typical applications include retail lighting,
commercial down lights, high bay, outdoor and street lights, and entertainment lighting.

Product Nomenclature
The part number designation for Bridgelux LED Arrays is explained as follows:
BXRA – AB C DEFG – H – IJ
Where:
B X R A – Designates product family
A B – Designates the nominal ANSI color temperature; 27 = 2700K; 30 = 3000K, etc.
C - Designates minimum CRI; C = 70, E = 80, G = 90
D E F G - Designates Nominal Flux; 4000 = 4000lm, 7000 = 7000lm, etc.
H – Designates configuration
I J – Designates CCT color binning
03 = 3SDCM or 3-step
04 = 4SDCM or 4-step
00 = 7SDCM or 7-step

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 at the nominal drive current with case temperature maintained at or below 85°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 comply with the European Union directives on the restriction of hazardous substances in
electronic equipment, namely the RoHS directive. Bridgelux does 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 secures UL recognition for all the LED Array products. Please refer to the UL file E350613 for the
latest list of UL recognized Arrays. 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.
CE Recognition
In accordance with the relevant European Union directives, the family of LED Array products conform to the
applicable requirements of the IEC/EN 62031:2008 (LED Modules for General Lighting Safety Specifications)
and IEC 62471:2006 (Photobiological Safety of Lamps and Lamp Systems). Bridgelux maintains a CE
Declaration of Conformity statement on its website and displays the CE mark on product packing labels.
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.
Case Temperature Measurement Point
A case temperature (T
c
) 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.
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.

Cautionary Statements
CAUTION: CONTACT WITH OPTICAL AREA
Avoid any contact with the optical area. Do not touch the optical area of the LED Array or apply mechanical
stress to the yellow phosphor resin area – it could damage the LED Array.
Optics and reflectors must not be mounted in contact with the yellow phosphor resin area (LES) or the white
ring that surrounds the yellow phosphor area. Using the white ring to secure optics can result in damage to the
LED Array as the ring is not designed to act as a mechanical locating feature. Optical devices may be
mounted on the top surface of the LED Array substrate outside of the white ring maximum OD as specified in
the product data sheet. Use the mechanical features of the LED Array substrate edges and/or mounting holes
to locate and secure the optical device as needed.
CAUTION: EYE SAFETY
Eye safety classification for the use of Bridgelux LED Arrays is in accordance with IEC specification EN62471;
Photobiological Safety of Lamps and Lamp Systems. Bridgelux LED Arrays are classified as Risk Group 1
(Low Risk) when operated at or below their rated test current. Please use appropriate precautions. It is
important that employees working with LEDs are trained to use them safely.
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.
CAUTION: CHEMICAL EXPOSURE HAZARD
Exposure to some chemicals commonly used in luminaire manufacturing and assembly can cause damage to
the LED Array. Please consult Application Note AN11 for additional information.
