I asked HLG customer service what they recommend be used to wire the driver to my 260 to a location other than the heatsink.
This is the reply
homedepot “DOT” com/p/Southwire-By-the-Foot-18-3-300-Volt-CU-Black-Flexible-Portable-Power-SJOOW-Cord-55811799/204632935 ** 6 Feet of extension wire
You will disconnect the barrel connector from the “OUTPUT” side of the driver, add your length of wire in, New connector on bare end, and reattach driver to new connector.
Thank you for contacting HLG Customer Support
