I picked up one of these little lights a few weeks ago. Shop SYLVANIA Black LED Night Light with Motion Sensor and Auto On/Off at Lowes.com I finally installed it on the side door of my shop. Let me tell you this sucker is slick! It senses me from at least 25ft away and seems to stay lit unless no motion is sensed for 5 seconds or more. For $13 im gonna grab a few more since it looks like they might be discontinued.
I've got 7 of these solar lights. All-Pro 100° Black Motion Activated Solar Powered LED Flood Light-MSLED100 - The Home Depot Have had 2 up for 4 years and haven't replaced a battery yet. They pick up motion a long ways off. One in my drive about 80 ft off the road will light up on a drive by. If you watch Amazon they go on sale occasionally for around $18.
60 LED Solar Security Light I put up a couple of these for getting in the wood in the dark. They work great and recharge fine, though they get dim quickly after a cloudy day. Best part was getting one for cheap because the mounting screws were missing.
Mine was in the middle of a field with southern exposure so it couldn't have been the sun. Shortly after I put it up it started to act up. The light stopped coming on but when I walked by it I could hear it clicking but it didn't light?
