From researching a few lights I've noticed that some have a variable strobe how is that any better or worse than a regular set strobe? What is the reasoning and the pros and cons of each? I don't kid myself thinking that the strobe is going to stun and shut anyone down but I do think it buys you a couple extra seconds you might need. I would think a faster constant strobe would put more blue dots in someones line of sight than a slower strobe. Or by being variable it doesn't allow the eyes to adjust?
