Wakefield- Vette's DUAL LED Series heat sinks are
extremely versatile for a customer's application
whether they require either an active or passive
solutions. Each DUAL LED Heat Sink has a built-in
option which lets the customer add a standard, silent
fan in less than a minute, with just four screws, and get
more than a five-times improvement in thermal
resistance and wattage rating up to 750 watts.
Single-Piece Forged-Aluminum Construction For Low
Thermal Resistance & Compact Form-Factor
Eleven Models Ranging from 58 mm to 225 mm Diameter
with Thermal Resistance As Low As 0.35 Deg C/W For
Passive Cooling up to 150 Watts
Compatible with all SMD LED arrays, COBs, and “Driverless”
AC-LED’s From All Major LED manufacturers

LED Heat Sinks
DUAL LED Heat Sink- Active & Passive w/ Fan Attachment
www.wakefield-vette.com
All DUAL LED heatsinks have pre-drilled and tapped holes in the baseplate
so that a fan can be attached to the pin side (blowing air into the pins) with
just four 6-62 screws of proper length (or longer screws with appropriate
washers or spacers. Wakefield-Vette lists the DUAL LED heat sinks and
suggested fan type to achieve silent operation and life expectancy
approaching 100,000 hours. Please note that we recommend fans with dual-
ball-bearing and DC brushless type motors.
For Use in Active Cooling Mode...
The heat sinks are manufactured to accept four 6-32
screws, which can be inserted through thefour fan-
mounting holes and into the four tapped holes in the
baseplate. Fan power to achieve the rated thermal
resistance should be < 1 Watt. Please contact
Wakefield-Vette to discuss power supply and fan
options.
Please take into consideration the heat sink total
height and fan thickness when selecting the length
of 6-32 screws to be used. If slightly longer screws
are purposely used to ensure extension beyond the
heat sink baseplate (>1/4”), then standard 6-32 hex
standoffs can be employed to enable a variety of
enclosure attachment/mounting methods.
