Yes thers are several types of IR Led: All within INFRARED 700nm - 4.9µm.
Try: Siemens SFH485
I suggest you place fifteen groups of six LEDs and one series resistor each.
Try and place them on a PCB 3-4 inches round.
With a voltage drop across each LED of 1.5 volts and a current of 100 mA, the supply voltage required would be at 12 volts (actually 9 volts, but more is preferred to give some overhead for the resistors to regulate the current), and the current draw would be 1.5 amps.
