i have had a few trial and error homemade light systems.
1. the T-post/hog tube light. it fits over the post that the tube is connected to.
i first found that the 55 watt light pulled too much power. i switched them out with 12 volt led bulbs in drop light cans.
i found out that the motion switch on the bottom of the box in the center was not as weather proof as i thought.
2. EW feeder light and motion switch. work great and got a bunch of kills but it drained the battery (feeder battery) and because the motion switch was not weather proof then i had to put it up for hunts and then take it down.
3. current setup.
moonshine light with solar panel that stays out all the time.
and extra light during hunting from a Dorcy ceil light.
i did make a bracket that i mounted the base for the Dorcy light so i can put it up and take it down easily.
you can see my latest addition to my feeder. the raccoon had ripped out my timer, battery and chewed all the wires. i brought the feeder to the house and dual propose enclosure to keep raccoon out and divert the corn under the feeder into the lights.
