Grow Light Bulbs

Our grow light bulbs provide an easy and efficient way to introduce plant-friendly lighting into any lamp, fixture, or ceiling socket. Available in LED and fluorescent formats, these bulb grow lights provide the full range of light wavelengths needed for healthy plant growth, from blue for leafy development to red for flowering. With wattages ranging from low-output propagation bulbs to high-power bloom options, they cater to a variety of indoor needs.

Designed for plug-and-play convenience, these light bulbs for grow lights run cooler and last longer than traditional incandescent or HID options. They’re ideal for starting seedlings, supplementing indoor gardens, or adding light under shelves and in tight spaces. Explore our wide collection and find the best fit for your grow setup!
