5027 TFFC Star K2
High-Power LED Light Module
DATA SHEET Page 1 of 5
TM
Product Overview
An electrically isolated star capable of delivering over 300 lumens
per LED, the TFFC Star K2 offers greater application capabilites
because of its size and ease of integration into fixtures and OEM
applications. Using the popular LUXEON® K2 with TFFC emitter,
LUXdrive designed the TFFC Star K2 with an identical footprint
as the LUXEON® I and III and V Stars. Inherent electrical
isolation means thermal interface materials are not required to
be electrically insulative. The TFFC Star K2 is available in cool
white, neutral white, and warm white. It also can be used with
any of the 20mm optics available from LUXdrive.

Heat Sinking and Mounting
The TFFC Star K2 has 6 mounting points that use #4 screws for attachment to an appropriate heat
sink. To ensure proper thermal management, the Star K2 should be affixed to an additional metal
heat sink (copper or aluminum) using a thermal interface material, with the heat sink exposed to
free air. Use an infrared thermometer (or similar instrument) to measure the surface temperature
of the MetalCore printed circuit board to gauge heat sink performance per the chart below.
The TFFC Star K2™ MetalCore printed circuit board has a backing plate that is electrically isolated
from the emitter. When selecting a thermal interface material, it is not required to be electrically
insulative.
Drivers
LUXdrive offers a line of drivers designed for use with high-power LEDs modules such as the TFFC
Star K2. The choice of driver will depend upon numer of LED modules to be driven, the input
voltage source, and the desired forward drive current. See the full line of LUXdrive products at
www.LUXdrive.com
Optics
The TFFC Star K2 can be fitted with a wide range of optics, offered by LUXdrive. Available lens
holders are clear, but white or black can also be specified. There are four standard illumination
patterns available: spot (5°), medium(15°), wide(25°) and oval (5° x 20°). See the diagrams on page
4 for examples of typical illumination patterns.
