This 4ft light bar is a versatile solution for vertical farming or shelf-based indoor gardening. At 40W, it provides a steady stream of full spectrum light that is perfect for seedlings, leafy greens, or clones. The long, slim form factor allows it to be mounted directly under shelves to save vertical space.

The single panel design ensures that light is directed downward where it is needed most. It is lightweight and easy to install using standard clips or hanging kits. This bar is an excellent choice for those who need to illuminate long rows of plants without the bulk of a traditional square fixture.

Energy efficiency is a key feature of this model, allowing for multiple units to be used in a single room without excessive power draw. The full spectrum output ensures that plants receive a natural light profile for healthy development. It is a practical tool for organizing and lighting a multi-tier grow system.
