LED DIYers rejoice! This little number is a kind washer specially designed to fit on top of a high-power star mounted LED. Its channeled pathways allow to hold your wiring in place, elimintating the need for solder!
Let's face it, those little stars are a real pain to solder correctly. Even with a good bit of soldering experience and the right equipment, they're difficult at best to get mounted properly (especially when they're mounted to a large heatsink). This hold down makes the process of wiring your star mount LEDs trivial. Simply drill and tap your heatsink as usual**, place your thermal compound and LED, fit a holddown over top, and screw down part-way. When you get close to the bottom, insert your wire and tighten down the screws. Done.
This model is speciall designed for CREE XP series LEDs and is compatible with CREE XP Optics!
** Remember, if you're using an aluminum heat sink and steel screws, tapping isn't even necessary.
