I like small mods that make a big difference. It’s simply a better Magelight that comes in various colours. If you’ve got lighting mods that make dark places really dark, it’s all the more useful. I like the red one, since it looks okay and a backyard astronomer long ago told me that red is the colour to use to avoid spoiling your night vision.
It may require a bug fix or two if you want to put down large numbers of lights everywhere, such as along the roads as you travel at night in the fog at new moon. I think it was possibly the Community Shaders “light limit fix” which made that work for me.
But even without that, it’s nice to be able to stick a few long-lasting colourful lights on the ceiling in the course of a dungeon crawl to light up a big area when your cover is blown and you want to see what’s going on, and to mark where you’ve been. Or depending on other lighting settings, just make it possible to see who you’re talking to in the Ragged Flagon. It changed Magelight from something I never bothered using to one of my most-used spells.
The lighting in Skyrim has always been one of my gripes with it. Most things in default Skyrim are fairly bright, which is lovely for playability, but makes it so torches and magelight are almost useless. Then if you slap an enb on, suddenly everything not 2 meters ahead of you is just pure impenetrable darkness.
Mods like this kinda fix it, but sometimes the light range is super short, or you have the ball of light stuck at the top of the screen in first person (or is that candlelight?).
Anywho, good recommendation, even if magic mods sometimes claim incompatibilities with stuff like this.
