Capt Craig is dead on. From the type of light, the angle and all. My installation consist of a T-post and strapping the light to it with tie wire.
I came up with same conclusions after years of playing with lights.
I use the Lowes landscape light since they are near me. Lowes landscape light

It is basically the same thing as the Home depot one. They stay on for about four hours which is longer than I care to stay. In the summer they last longer since they get to charge longer.
I have shot many coons under these lights too.

I am planning on doing this setup on my main bow feeder. It seems like a great idea. I will post updates. Thanks for the info.

I have deer, hogs, coons, possums, rabbits all come in at night. Recently I have had a coyote coming in and laying off to the side watching the feeder. He will not walk through the light, but he does walk by to see what might be there eating. I haven't had any cats on cam yet.

You ihad chance ta get set up? Last night heard hogs in distance. They didnt come my way. Two of my cellar lights are out. Thinking its batteres. best wishes

Try the green Kill Lights..dusk till dawn..has magnets on it..use a solar panel to keep the batteries up and running..

Haven't had a chance yet. I'm going to the lease this weekend to hunt. Went to fill feeders and check game cams last weekend. Had pictures of one of the sounder right under the feeder with the light shining on them. I guess it took them about three days to get brazen enough, but it was nightly after that. Thanks for all the great info. I'm definitely going to get a set up like the captains soon. I'll post updates.

Best wishes. My tree stand sit right on trail that comes from food plot, were have the lights, the old spinner feeder, & were have pvc gravity feeder, & comes out were trail cam sits facing new spinner feeder & deer stand. Two days in row found hog tracks in trail were cleared leaves away. My lights been their on old tent poles for few years. Just gotta be their at right time.

Glad it is working out for you. Here is the second part of the equation. When the pigs come in, let them feed for about 4-5 minutes. Real minutes, not the 45 seconds that feels like 5 minutes. This allows the pigs to get calm and for you to slow your heart rate and breathing. Pigs can't tell time, but they can get shy of a feeder if the moment they approach, a gunshot goes off. Since they can't tell time, 5 minutes allows them to approach, not get shot at and then start feeding. After they are actively eating, they relax and their heads are down. This way they won't see a flash and they won't associate the shot with walking in. They will walk in many nights you aren't there hunting. The goal is to avoid having anyone shoot while they approach!!

Thanks for the advice captain Craig. I will hold off until they are comfortable. I'm taking my 11 year old son to try and get him his first hog, I hope it all works out. I can't imagine how long those five minutes will feel to him.

Here's what I've used:

They seem to last a couple of years, depending upon the weather. The hogs where I hunt don't seem to mind the light.

These guys just want the corn, and the light shining from the left (just out of view in this photo) doesn't bother them.
