LED grow light bulbs keep your indoor plants healthy and thriving in a more energy efficient manner than incandescent and fluorescent alternatives. They emit virtually no heat and have incredibly long lifespans, while capable of producing a color spectrum conducive to both vegetative growth and blooming. For safety, you should avoid staring directly at these and use protective eyewear when stated.

LEDs are said to offer the most desirable conditions for growing plants indoors. You may be wondering why the bulbs often give off a purplish glow. Since plants need both red and blue light to grow, the combination of these creates the rosy color you see in many models, such as the Esbaybulbs and Hola ones featured here. If purple moodlights aren’t your thing, however, many products use the necessary colors but incorporate them in a way where the light remains a more natural, white color. For instance, the Philips Par38 and Sansi 40W on our list are reliable options that provide a warm, sunlight-like color to get the job done. For an all-in-one choice that conveniently comes with a fixture – and at a reasonable price – look to the Simple Deluxe Lamp, which can be clamped onto shelving to hold it above your plants. No matter which you choose, make sure it offers the size of coverage you’re looking for. In addition, for safety’s sake, avoid staring directly into your lights, and wear protective eyewear (often called grow glasses) when you are near them.
