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 (Tc) 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.

Typical Luminous Flux vs. Current
Typical performance at any drive current can be derived from the current versus voltage characteristics
shown in Figures 2, 3 and 4 and the flux versus current characteristics shown in Figures 5 and 6.
Normalized typical flux corresponds to LED tested under pulsed conditions where junction temperature =
case temperature = 25°C.
Figure 4: Typical Flux vs. Current – BXRE-xxx-0800-A-xx
Figure 5: Typical Flux vs. Current – BXRE-xxx-0800-B-xx
Note: Bridgelux does not recommend driving high power LED Arrays at low currents. Doing so may
produce unpredictable results. Pulse width modulation (PWM) is recommended for dimming effects.
