Works around the photo light cell change bug by deactivating the light when you sneak and reactivating it when you stand up (also increases sneaking ability due to less lighting). This ONLY WORKS with the DEFAULT BRIGHTNESS photolight HUD item however you are free to apply my changes to all the other photolight variant items as well using creation kit (changes don't show up in fo4edit). 

Installation: Replace the original photolighit.esp with mine. Original photolight mod required, which you can get from here: photolight download . 

Mod organizer 2 users: Right click on the original installed photo light mod and click open in explorer then drag and drop my photolight.esp over it.

I originally uploaded this on mediafire and posted it in the discussion page but after contacting the original author it seemed like they were no longer working on this mod so I'm uploading this workaround to help out more ppl who is tired of the lighting going out when changing cells.

Creation Kit Editor guide:

All I did to make it deactivate and reactivate when getting out of sneaking is by adding the target condition "IsSneaking" with a Comp of != and a value of 1.00 set to AND to the magic effect "DetectLifePhotoLightCloakEffect", which is used by the default normal photolight HUD brightness level. Therefore, photolight will not search for people to lightup when sneaking but when you get out of it it'll run the detection again thus fixing issues with cell changes and photolight not rerunning its searches on your previously lit up companion.
