Yes, the website was
www.hog-hunting-guide.com.
The manual your "friend" bought was a DIY manual for building feeder lights I sell there.
The light you built was a 6 watt red feeder light with flood light lenses.
That's not even the brightest red light I sell. :0
There is a photocell that is available with the kit, but it was opted out of in this order. IMO a photocell is optional with red lights anyway. I just leave mine with one cable connected to the battery and connect the other when I go to my stand. Disconnect when I leave.
I set a solar trickle charger on the battery to keep it charged between uses. Really easy.
Set up gets a little more complicated when you can't leave your lights in place, though.
The biggest thing you'll have to be careful when you set up with getting the game used to it is the scent. They can't see the red light (they can see the light source, though).
They'll know something's a little different, but it won't be the color of the light.
Hope that helps. Good luck!
