Several years of research, development and testing created the ultimate affordable and portable feeder light for night time hog hunting and game observation. The Kill Light® Feeder Light can be self powered for several days and nights by utilizing the built in photocell with power supplied by 4 C batteries (not included) or by attaching the auxillary power cord. The special 24 green LED's will not spook game animals, hogs or other varmints.
