PRODUCT DATASHEET Spotlight Cooler 70W LED Heat Sink This LED Heatsink is part of the Nuventix scalable LED portfolio. Future proof – Designed with the rapidly evolving light engine industry in mind, thermal performance can be easily increased or decreased without a luminaire redesign by adding or removing a SynJet Cooler Flexibility – Configure to order luminaire production process, use heatsinks for low lumen applications and the SynJet Cooler with heatsink for higher lumen versions Freedom – Compatible with most major light engines so thermal solutions and mechanical interfaces do not have to be redesigned when changing light engines Fast – In stock and ready for overnight delivery, worldwide Specifications Thermal 1 Mechanical Thermal Wattage Heatsink Θs-a2 Heat Sink TRise Above Ambient 22 W 1.2 (°C/W) 27 (°C) Finish Black Anodized 32 W 1.1 (°C/W) 36 (°C) Weight 433g 42 W 1.1 (°C/W) 45 (°C) Regulatory RoHS Material Size 6063-T5 Al Extrusion Diameter: 134 mm Height: 42 mm The chart below summarizes the thermal performance of all round LED heatsink solutions with diameters from 118 to 138 mm.

Thermal resistance values are given as reference only and are measured in free air without airflow obstructions. Thermal resistance is measured from the bottom middle of the heat sink to ambient air, with a heat source of 19 cm2. Actual thermal performance may vary by application and final product design should be tested to assure proper thermal performance. 2 4635 Boston Lane Austin, TX 78735 Phone: 512-382-8100 www.nuventix.com MKTG-DOC-000166 Revision A01 Oct 2012 PRODUCT DATASHEET Mechanical – LED Heatsink shown with Configurable heat sink All dimensions are nominal and in mm unless otherwise stated.
