so far i've always worked in the area of 100-250 for bright lights and <100 for dimmer lights/effects (e.g. to simulate the glow of the exit sign model) however, when i was looking at the decompiled maps, i noticed valve's lights are usually in the region of 800-1400. so what's the deal? now i've never found the maps i've made to be dull/noticeably darker than the valve maps, but i'm curious as to what others use for brightness values. as an example, here's a screen from cp_lumbermill: the light entities in this room have brightnesses of 100 for the flourscent hanging lights and 80 for the wall lights. similarly; reservoir's lighting - most are between 100-200.
