These are part of my low cost range of 1 watt power LED emitters. They produce around 50 lumens of red light (around 625nm) at 350mA. They are supplied ready to go on a standard star PCB, just attach them to a suitable heatsink and you're done.
Forward current: 350mA continuous
Forward voltage: 2.0 - 2.8V
Luminous flux: 50 lumens typical
Beam angle: 120°
