Customer Reviews

Large, well-lit flood area

The flood area is consistent and bright, allowing me to position the light higher to cover more and to be shadow-free when I need to rummage about in the shed/closet.

Best motion sensor light ever!

Found these while looking for light bulbs and bought them on a whim. They are great lights for any place you need to see before you actually get there! That's how sensitive the motion sensor is! This is a great product, and I'm sure we'll purchase more of them.

Going great after 18 months

I bought one of these spotlights at a big box hardware store on a whim, needing a light for northwest winters (lots of rain) for my treks out to put the animals in at night. LOVE IT! Comes on when I get close, stays on just the right amount of time and goes off automatically. Holds up to wet northwest winters really well. After one year, the batteries needed to be replaced. Simple to change out the batteries and going strong again. Just bought a four pack for more areas that need a little brightening up.
