Here is a useful idea for shedding light on dark places, like closets or underneath cabinets.
Rechargeable LED light strips are a fantastic lighting solution for those dark spaces.
Very thin and lightweight, some have magnetic strips that stick to the underside of shelves or cabinets. The light strip itself attaches to the strip with a magnet. Every two months, remove the strip and recharge for a couple hours.
Some strips also are triggered by movement, so when the closet door opens, or when you use the counter, the light comes on automatically.
