Value is max(R,G,B). So (0,255,0) (quite bright), (255,0,0) (moderately bright), (0,0,255) (not so bright), and (255,255,255) all have the same "value": 255.
When you use Levels on "Value", the range of the R/G/B channels are stretched/compressed appropriately. Ideally, Levels would use HSV, HSL or better, Lab models...
