night hunting can be very productive, be very carefull hogs eyes generally don't shine. I have noticed that they shine better under an LED light.
As far as bright lights I haven't noticed it bothering hogs unless they have been shot at a lot.
I have had hogs stand there like nothing was going on truck running lights blaring never had a problem.
If your sitting in a blind I would leave the light on low and constant until the hogs show up, solar yard lights work great but need to be mounted on a T post to keep the hogs from rooting them up.
good luck and show some pics!
