LED lights function a bit differently than more traditional fluorescent grow lights. Though they are a good choice for nearly any growing setup, it’s important to know that a ballast is not a requirement for this style of light. A ballast is essential for fluorescent lights as it regulates the flow of electricity to your lights. This helps to prevent overheating and reduces fire risk.
LED lights function differently than fluorescent lights and instead require a direct current which is typically integrated into the fixture. Overheating is less of a concern for LED lights as they are more efficient and do not produce as much heat. A ballast is inexpensive and not something you need to stress over if you do have fluorescent lighting. Knowing how your light functions is a good idea and can help you better understand the limitations and benefits of your chosen indoor grow lights.
