These are 2 watt power LED emitters that produce a great deal of purple light. The interesting thing about these is that they contain two 1 watt chips - one red and the other blue - that are wired in series, so both chips get the same current. The light from both chips combines to produce purple.
As these are a bare emitter, you must mount them on a suitable circuit board, such as our generic power LED star PCB, and use adequate heatsinking. Simply glue them onto the PCB with a suitable heatsink glue (available from the cooling and heatsinks category) and solder the tabs to the PCB.
