Compact, hands-free light for closets, pantries, and small storage spaces.

Find your shoes in the closet. Put groceries away in the pantry. Reach into storage for the supplies you need. The IQ America CL3645 adds convenient motion-activated lighting to smaller spaces without running electrical wiring.

This compact battery-operated ceiling light delivers 450 lumens of 4000K neutral-white LED light. Adjustable brightness and Lux Learn let you tailor operation to the location. Each fixture requires four C-cell alkaline batteries, not included.

  • LIGHT SMALL SPACES WITHOUT WIRING: Add 450 lumens of neutral-white LED light to closets, pantries, and suitable storage areas. The compact IQ America CL3645 battery powered motion sensor ceiling light operates without a hardwired electrical connection.
  • HANDS-FREE CLOSET AND PANTRY LIGHTING: Carry groceries into the pantry or reach for clothing without searching for a switch. The motion sensor activates the light when movement is detected and ambient light is below your selected threshold.
  • ADJUST BRIGHTNESS TO YOUR SPACE: Use the DIM control to choose full output or reduce brightness down to 20%. Tailor this dimmable battery ceiling light to a smaller storage area while reducing battery consumption at lower settings.
  • SET YOUR OWN DARKNESS THRESHOLD: Lux Learn lets you customize how dark the location must be before motion activates the light. Adjust activation for a dim closet, pantry, or utility space.
  • COMPACT FIXTURE, FLEXIBLE PLACEMENT: Mount on a suitable ceiling, wall, or eave with the included hardware. The weather-resistant design supports indoor and outdoor locations according to the instructions. Requires four C-cell alkaline batteries per fixture, not included. Three-year limited warranty.

Make Overlooked Spaces Easier to Use

Add hands-free light to a closet, pantry, linen-storage area, or suitable under-stair storage space. Position the fixture where motion detection and overhead illumination help with quick everyday visits.

The CL3645 is the compact, lower-output option in this three-model family. For more light output, compare IQ America CL3680 — 800 lumens and IQ America CL3711 — 1150 lumens.

Motion-Activated Convenience

The light activates when movement is detected and the surrounding light is below your selected threshold. Ceiling-mounted 360° sensing detects movement around the fixture.

Choose placement according to the installation instructions. Detection coverage does not specify how much floor or shelf area receives a particular level of illumination.

Choose the Light Level That Works for You

Use DIM to adjust brightness, whether you want full output to find stored items or lower output for a smaller space. Lux Learn lets you set the darkness threshold that permits motion activation.

Install Without an Electrical Connection

Mount the fixture on a suitable ceiling, wall, or eave using the included hardware. Its weather-resistant construction supports indoor and outdoor applications within the manufacturer’s installation requirements. Also consider a small shed or covered entry where the mounting surface and operating conditions meet the manufacturer’s installation requirements.
