Great for Wii sensor bar – 5mm IR LED Emitters (20-Pack) Reviews

Cheap, large quantity (got 21 in a pack). Use 12 to make two groups of 6 to make a Wii wireless sensor bar. It works perfectly.
No product info. Thin legs. Not as bright in the IR range sensed by WiiMote. The emitted light may have a shorter wavelength as it is somewhat more visible.
I first tested it with 1.5V and it lighted up. Then I put 6 of them in serial with a green LED (as power indicator) on each side and powered both groups with a 9V DC adapter in parallel.
A total cost of less than $3 for a wireless sensor bar that works over 18ft. Suffient to make 1-2 sensor bars. 1.2V drop per LED works. Use 6-7 of this to elimiate the need of a resistor.
