FWIW I found when using the green light a lower setting is good if the pigs are within 50 yards or so...the brighter setting will spook them at close range. Farther out, brighter is better, but I like to spot them in the 'halo' of the light, then lower the light, and the boom on them
Geedub has a lot more experience at this than I do, so hopefully he will chime in.
