Bridgelux Micro SM4
Product Data Sheet DS27 – PRELIMINARY, Expires 03/31/12
Introduction
The Bridgelux Micro SM4 delivers high performance, compact and cost-effective solid-state lighting
solutions to serve general and specialty lighting applications. These products combine the higher
efficacy, lifetime, and reliability benefits of LEDs with the light output levels of low wattage conventional
light sources. The Bridgelux Micro SM4 series has been designed to enable a cost-effective design for
LED retrofit bulbs, halogen spotlights, consumer luminaires and other general lighting applications.
The Bridgelux Micro SM4 provides a high performance alternative to conventional solid state solutions,
delivering between 400 and 500 lumens in warm and cool white color temperatures. These compact high
flux density light sources enable both diffuse and directional lamp replacements for a wide range of
applications.
Lighting system designs incorporating these products deliver performance comparable to that of a 20-40
Watt incandescent, 20-35 Watt halogen and low wattage compact fluorescent lamps and luminaires and
feature increased system level efficacy and service life. Typical applications include replacement lamps,
task lighting, under cabinet, accent, pendant, sconces, porch, pathway, landscape, portable, and
consumer luminaires.

Product Nomenclature
The part number designation for the Bridgelux Micro SM4 is explained as follows:
BXPX – AB C DEFG – H – JJKK
Where:
BXPX – Designates product family
AB – Designates the nominal ANSI color temperature; 27 = 2700K; 30 = 3000K, etc.
C - Designates minimum CRI; C = 70, E = 80, G = 90
DEFG - Designates Nominal Flux; 0400 = 400lm, 0520 = 520lm, etc.
H – Designates configuration; A = 350mA; B = 700mA
JJ – Designates CCT Bin options
00 = Full ANSI
03 = 3 SDCM
04 = 4 SDCM
KK – Reserved. Default = 00
Average Lumen Maintenance Characteristics
Bridgelux projects that its Micro SM4 family of 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 solder pad 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 LEDs 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 products: lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE).

UL Recognition
Bridgelux secures UL Recognition for all the LED products. Bridgelux uses UL Recognized materials with
suitable flammability ratings 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 the Bridgelux Micro SM4 product series is in accordance with IEC –
EN62471 Photobiological Safety of Lamps and Lamp Systems specification. These products are
classified as Risk Group 1 (Low Risk) when operated at or below the 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 during operation. Allow the LED to cool for a sufficient period of time before
handling. The LED 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. Please consult Bridgelux Application Note AN21 for additional information.
