Culling candle glow textures within a cell

[LLPerpJ]

I just had a quick question for some more experienced modders as I've run into a bit of a roadblock on a mod edit that I'm trying to wrap my head around.

 

So the question is, how exactly can I change the culling distance for glow textures, such as candles or fire, within certain cells? i.e. having to be within a certain distance before the glow/lens flare textures appear. Any and all help would be greatly appreciated.
