Light_StrobeDoom

From ZDoom Wiki

232:Light_StrobeDoom (tag, u-tics, l-tics)

tag: Tag of affected sector 
u-tics: Time to stay at upper light level 
l-tics: Time to stay at lower light level 

This is the same as Light_Strobe except that upper is whatever the sector's light level is right now, and lower is whatever the lowest light level in the surrounding sectors is. If the surrounding sectors are at the same light level as the affected sector, then lower is 0.
