IR Hack - additional LEDs in parallel

[Leav]

I was thinking about hacking a TV remote by adding additional LEDs to it, hopefully making it stronger and more likely to reach the robot through all sorts of visual obstacles.

would wiring additional LEDs in parallel enhance the signal?
Electrical circuits are not my strong side.

I can gather that the additional LEDs will lower the overall resistance of the circuit, thus increasing the current draw which should theoretically increase the power p=VI so for a given V=const, larger I means larger P, right?

also does anyone know if all Remote controls use an interchangeable IR LED? could I dismantle some from any old remote?
could I buy a bunch at the local electronics supply store?
thanks for the help!
