2W 445nm M140 Blue Diode in Copper Module W/Leads

Listing is for a single 2W M140 445nm blue diode mounted in a 12mm x 30mm copper module with leads attached. The copper module upgrade provides a huge improvement in thermal conductivity over the standard brass module for moving the heat away from the diode to your heatsink which gives a much more stable output from the diode. Please Note this module comes with an acrylic lens in it to keep dust out. It can not handle the power this unit can put out. It will keep contaminates out of the module until you are ready to put yours glass lens in. Replace with your glass lens of choice before powering the module. The best options are the Aixiz 405/445 Glass Lens or the 405 G-1 Lens. If you need a lens with the unit I do offer this unit in a combo with a three element or with the G-2. See my other listings. Save yourself the headache of pressing and soldering. Just add host, heatsink and driver. The current must be limited to no more than 1.8A to the diode. Wire assignment is: Red + Black - White Case Diodes are current hungry and as they heat up their internal resistance is lowered causing them to want to draw more current. Don't attempt to connect the diode directly to a fixed voltage source like a battery. You must use a proper LD driver like an X-drive limited to no more than 1.8A or you diode will suffer thermal runaway and die. If you don't already have one see this one. http://www.amazon.com/gp/product/B00V5CF0MU
