Top Side Part Number Markings
Vero includes a top side part number marking to help simplify inventory management and increase opportunities for production
quality control. Any Vero product can be quickly identified to determine the product configuration, color or CRI by simply looking at
its top side markings. Unlike previous product generations where markings were included only on the back side of the array, no
longer is it necessary to handle (turnover), uninstall the array in an infield application or guess which product it is by the color of the
phosphor area. The Vero line of LED array products also has a 2D bar code which provides additional information and full product
traceability for quality control purposes.
Enhanced Connectivity Options
Vero’s thermally isolated solder pads have been designed to make soldering fast and secure. For those who prefer an even faster
solderless installation, Vero has a connector port that can be used to further simplify your manufacturing process, reduce inventory
cost and allow for field upgradability. The connector port mates to the Molex Pico-EZmate connector harness, sold separately by
Molex and through their distribution network. The Molex connector harnesses come in a variety of wire lengths and wire gauge
options and can also be custom engineered to meet your specific design requirements. Please consult your local Molex sales
representative or visit www.molex.com for more information.
Lumen Maintenance Characteristics
Bridgelux projects that the Vero 18 family of LED array products will deliver, on average, greater than 70% lumen maintenance after
50,000 hours of operation at two times the nominal drive current in Table 1. This performance assumes constant current operation
at up to 2 times the nominal drive current with case temperature maintained at or below 85°C. Continuous use beyond five years
may result in a lower lumen maintenance. For use beyond these 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 LM-80. 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. Vero 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 any LED array products: lead, mercury, cadmium,
hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).
UL Recognition
Bridgelux secures UL Recognition for all of its LED array products. Please refer to the UL file 357031 for the latest list of UL
Recognized Bridgelux LED arrays. Bridgelux uses UL Recognized materials with suitable flammability ratings in the Vero LED array
products to streamline the process for customers to secure UL listing of the final luminaire product.

Page 4 of 17
CE Recognition
In accordance with the relevant European Union Directives, the BXRC series 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 measurement point location is included on the top surface of the Vero 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 which correlates 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.
Consistent and repeatable temperature measurements can be correlated to the data sheet performance specifications and to
published LM-80 reliability data. The use of the case temperature measurements point is fully explained in AN30.
CAUTION: CONTACT WITH LIGHT EMITTING SURFACE (LES)
Avoid any contact with theLES. Do not touch the LESof the Vero LED array or apply stress to the LES (yellow phosphor resin area).
Contact may cause damage to the LED array.
Optics and reflectors must not be mounted in contact with the LES (yellow phosphor resin area). Optical devices may be mounted
on the top surface of the plastic housing of the Vero LED array. Use the mechanical features of the LED array housing, edges and/or
mounting holes to locate and secure optical devices as needed.
CAUTION: CHEMICAL EXPOSURE HAZARD
Exposure to some chemicals commonly used in luminaire manufacturing and assembly can cause damage to the LED array. Please
consult Bridgelux Application Note AN31 for additional information.
CAUTION: EYE SAFETY
Eye safety classification for the use of Bridgelux Vero LED arrays is in accordance with IEC specification EN62471: Photobiological
Safety of Lamps and Lamp Systems. Vero LED arrays are classified as Risk Group 1 (Low Risk) when operated at or below the
maximum drive 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 Vero LED array or yellow resin area during operation. Allow the array to cool for a sufficient period of time before
handling. The Vero LED array may reach elevated temperatures such that could burn skin when touched.

Mechanical Dimensions
Figure 9: Drawing for Vero 18 LED Array
Notes for Figure 9:
1. Mounting holes (2X) are for M2.5 screws.
2. Bridgelux recommends two tapped holes for mounting screws with 31.4 ± 0.10mm center-to-center spacing.
3. Screws with flat shoulders (pan, dome, button, round, truss, mushroom) provide optimal torque control. Do NOT use flat, countersink, or
raised head screws.
4. Solder pads and connector port are labeled “+” and “-“ to denote positive and negative, respectively.
5. It is not necessary to provide electrical connections to both the solder pads and the connector port. Either set may be used depending on
application specific design requirements.
6. Drawings are not to scale.
7. Drawing dimensions are in millimeters.
8. Unless otherwise specified, tolerances are ± 0.10mm.
9. Refer to Application Notes AN30 and AN31 for product handling, mounting and heat sink recommendations.
10. The optical center of the LED Array is nominally defined by the mechanical center of the array to a tolerance of ± 0.2mm.
11. Bridgelux maintains a flatness of 0.10mm across the mounting surface of the array.
12. Bridgelux Vero 18 LED arrays are packaged in trays of 20 units with a maximum planar dimension of 215.mm x 279.4 mm (8.5 x 11 inches)
per tray.
