This set contains two four foot grow lights that utilize a specific red and blue LED spectrum. This combination of wavelengths is often preferred for targeting specific growth stages, such as flowering and fruiling, or for boosting chlorophyll absorption. The 40W fixtures are designed to provide concentrated light energy where plants need it most.

The red and blue light output gives the growing area a distinct purple hue, which is the result of mixing these two essential wavelengths. These lights are particularly effective for indoor gardeners who want to supplement natural light or focus on the vegetative and blooming phases of their plants. The fixtures are lightweight and can be easily mounted in various configurations.

Each unit in this two-pack is built to be linkable, allowing you to run them in a series from a single power source. This makes them a great addition to a multi-tier plant rack or a dedicated grow tent. The focused spectrum helps in preventing stretching and encourages a more compact, sturdy plant structure for herbs and flowers.
