trouble with the light_spot entity

I downloaded the lighting prefab pack and i used some of the lights in my level but i noticed they were not bright enough so i decided to edit the light_spot associated with the prefab and i didnt get any change in light. so i made a test map with a light_spot and i tried messing around with it. ingame the level wasnt lit, it was pitch black but there was light on the first person model and it showed up where i had placed the light spot. i checked the compile log on interlopers.net
and there wasnt anythying wrong. so any ideas on whats wrong?

i've tried a cordon compile and i still have no errors. but i think i figured part of it out. i was testing and i made a light and a light_spot entity then i compiled and it work perfectly(it wasnt bright enough to light the intire room). then i edited the brightness setting to 800 and compiled,then it was pitch black

well it seems that psy was right. i thought that vrad would just ignore the lightbulb.
