Question Manually adjusting the Brightness and Warmth

I've recently bought the Kobo Clara HD and installed KoReader on it. Since I only read at night in the dark before bed, I thought the blue light filter on the Kobo Clara HD would suffice for that (I'm very sensitive to bright and blue light before bed).

Unfortunately, even at 1% brightness and maximal warmth settings on KoReader, it's still way too bright. I haven't used my Clara in weeks now since it keeps me up at night.

I read that it's possible to configure the "sysfs_light.lua" settings in order to decrease the brightness and increase the warmth/red colors and have been tweaking around with it myself without any success so far. I've also tried the settings on the following site (https://github.com/koreader/koreader/issues/4186) but I'm not sure if I'm doing things correctly in the first place.

I was wondering if someone else has some premade settings for lowering the brightness and increasing the warmth/red colors (/limiting the blue light emitted from the device) or can point me in the right direction what settings I should change and in what manner (increasing or decreasing the value).

I already found some other topics related to decreasing the brightness by changing the internal light of the device, but I'm not a very technical person and don't want to risk the warranty of the device.

I've attached 2 notepad files with my original "sysfs_light.lua" settings for KoReader and the latest settings that I've experimented with.

Anyway, thank you for taking the time to read this post!
