Wii USB sensor bar low range

so.. i modified my sensor bar and it works
i see red lights on my sensor bar through my phone camera
but its range is too short
it wasn't like this before
5 IR led is on each side(total led number is 10)
It's USB powered, which mean it is working on 5v
should i need voltage booster?

Is it an original Wii/U sensor bar? If so, yes, it requires above 5v (I forget how much, but shouldn't be hard to find out).

yes, it is original wii sensor bar
someone says 7.5v, and other says over 9v
i don't know which one to trust

The best way to do things is to measure the voltage across the LEDs when it's plugged into a Wii, and then replace the resistors so that there'll be the same amount of current with a 5V supply. IIRC, the real console spits out between 7 and 12 V depending on what's connected, as I think it's got a current limit or a fairly high internal resistance.
