Glowstick radius

[Mr. Lantern]

Hi, I've finished all 3 Penumbra games so far and Black Plague is by far my favourite, but I'd really like to go back and play Overture, but the massive radius of the Glowstick in Overture kinda ruins it for me, it gives almost no reason to use the flares or flashlight and I was wondering if there is any way to shrink it down in the game scripts, I've tried but I can't locate the right file or line, if anyone's done this or anyone knows how, it'd be greatly appreciated.
