Jumping out the resistor will improve the range, but be prepared for a reduction of life on the LED, so check it after every battle to make sure it is functioning OK. I use a socket mount, so I can easily replace an IR LED in seconds if I have an issue with one.


The guys who did the test in England were using a maplins IR LED, 144 ft is outstanding.!!!!
