I was wondering if there was a "best practice" way to setup phantom lighting for light sources you want to not have diminish at 1 unit per block. If you see the screenshots below, I have a street light that appears to be lighting up the area around it. In the second screenshot, I placed sponges where the phantom light blocks actually exist. Of course, if you place something where the light source is, it goes away, but I have written code to replace that block with the phantom light source if you break it. If you already have something in the place of where the phantom light is supposed to be, it will place the phantom light one block above. This could get kind of weird in certain situations, though, depending on who's using it.
Then I got to thinking of if I should place a bunch of phantom lights in a cone shape from where the overhang of the actual street light is all the way down to the ground. I haven't given this idea much thought, but maybe this is a preferred way to do this?
I guess what I'm asking is - are there any guidelines on how to do phantom lighting when you want to do something like this? Are there any good, clear examples someone could point me to that shows a good way to setup phantom lighting?
