A little while ago at work (EMS) while in station, I was in the bay (at night) and rather than light up the place with the overhead really bright lights, I figured that I would just use the ARC (the least powerful one)....a FF walked into the bay and came around the bus and was, "Shocked that all that light is coming from THAT!"

It is funny to read everyone's thoughts on how bright the ARC's are....I say this because I see people saying that they have the 'premium' or are 'thinking of getting the newer/brighter ARC'....I have the 'least expensive model' and I can't tell you the number of times I consider it OVERPOWERED for the task at hand......I can't imagine needing something brighter.......
