The 6P is just a Surefire flashlight, see link below for factory specs:

I'm going to get a couple of drop-in's from Nailbender for mine. I don't know the output of his drop-ins, but surely they are much brighter than factory. I am going to get the red led's, to eliminate the need for a lens cover.
I use this mount, but there are many others available:

Giving tips is a tricky thing, but I can give you some basic help. Frankly, since you will have a guide, they should give you plenty of tips that are specific for their area, game, and hunting technics.
I have to tell you that you don't want too much light, especially white light. The further you are from a hog, the less they are bothered by white light. Red light isn't generally a problem at any distance.
For using the light, don't give a sudden blast of bright light. I've had the best results by turning on my light while it is not pointed at them. Then I just lower the rifle onto them (remember, my lights are mounted on the rifle).
Twist-on or soft-touch switches are best. If you get a chance to shoot at a hog that is fairly close, the 'clicking' from your light switch can easily scare them away.
Natural sounds are okay, this will include your clothes shuffling, soft walking noises, whispering, and such. Any mechanical, snapping, or clicking sounds will usually end in the hogs running away.
If you are going to bait them with corn, take your time and pick the hog you want. Most of the time, your first shot will scare the rest of the hogs away. Sometimes they will return after several minutes, but normally they will be gone from the area. Don't rush yourself. If they are busy eating corn, noise becomes less of an issue. They are very loud eaters and you can hear them eat corn from 50 yards away (seriously).
Don't get over-excited and rush your shot. You don't want to miss or just wound a hog because you felt rushed.
If they put you in a stand, don't shoot the first hogs that arrive. Most often (though not always), the younger smaller hogs arrive at feeders first. The larger sows will often arrive several minutes later or be mixed in the sounder (group of hogs).
If you get a large lone hog, it's probably a male. Take the shot, but don't rush.
For stalking, you will need to be very aware of your surroundings. You will not only be looking for hogs, but also watch out for snakes in June.
If they plan to take you on a stalk hunt, you will probably find your hogs in very dense brush, low-lying areas, hidden in grass, or along creeks. They should stalk with you if that is the method you will employ. Groups should be of minimal size for stalking.
The best hog hunting is from approx an hour before sunset all the way through mid-morning.
Be prepared to have fun. Hog hunting is a lot of fun. Hogs are intelligent animals, so it can be a challenge some days.....other days they almost shoot themselves. The young smaller hogs are easiest to kill. The larger older ones are usually harder to get (which is why they are older...survival of the smartest here).
The kill zone of a hog is not the same as for deer. See below, also, be sure to read 'guns and tactics'.
