Defective... light would not stay lit more that about 1 second. Seems like it had a short somewhere. Going to reorder and try one more time, but so far, fairly disappointed! Had a hog hunt planned for tomorrow night, but it's off now .....

Update: I believe it was my error in trying to test this unit. Received a second one, and discovered my error. You must be in a very dark space to trigger this light. Sorry for my error on the original review.

My son says this is the best light for hog hunting

they don't even see the light and its great but uses a crap load of batteries

Works good. Not waterproof. C cell batteries last for a few weeks with constant usage

What I liked: Shipping was fast from seller. The light was bright enough that I could see well through a moderately price scope at over 150 yards. The concept of the light coming on slowly is a good one although it needs some serious refinement to be effective.

What I didn't like: immediately upon picking this item up my very first thought was that this thing feels cheaply made despite the $120 price. Upon further inspection my first impression was confirmed. (I used moultrie feeder lights before and they feel MUCH more robust although they have their own drawbacks) The unit comes apart into two halves to reveal the inner workings and battery compartment. The place where these two halves meet had inconsistent gaps, fitting together well in some places and with a larger gap in others. There is no chance this thing would be resistant to moisture. The whole unit itself just doesn't feel sturdy at all and I'd be afraid this thing wouldn't survive a drop from the bottom of my feeder. Speaking of falling from my feeder, the unit is supposed to have 3 rare earth magnets but mine had one missing and another one was put in crooked. There did not appear to be any glue in the recession that had the missing magnet and the magnet that was crooked was able to be pushed back in without much effort. This leads me to believe no glue was used to secure them which I think is a mistake due to the magnets strength, which is considerable, they could probably eventually pull themselves out when repeatedly putting them on an pulling them off your feeder.
When I opened the unit up to put in batteries I noticed one of the transistors was cocked at about a 45 degree angle. I lightly touched it and it went to the same position, flush with the circuit board, as the other identical transistors with no effort at all. The identical transistors were all very secure leading me to believe the loose one had received a poor soldering job. I think the connection was good as the unit did function correctly although a loose transistor doesn't exactly inspire confidence in this units longevity. As far as the light starting out low and gaining intensity I think that is an amazing idea and would probably be more effective if it went to zero %to 100% instead of about 20% immediately to 100% over about 30 seconds. When the light cut on as I was in my blind it did scare off whatever set it off each time it was activated, I won't blame that entirely on the light as the pigs at our ranch do get shot at a lot and are pretty skittish when the lights come on and bullets start flying. Overall I WOULD NOT recommend this product at the current $120 price without the mentioned refinements and better quality control. I boxed mine back up and returned it.
