About this item

Want to keep your indoor plants thriving even when there's not enough natural light? This 20W LED grow bulb screws into any standard E27 socket (the same as most household lamps) and provides the specific light wavelengths that plants actually use for photosynthesis.

The red and blue spectrum combination isn't random - it's scientifically designed with 166 red LEDs (630-660nm) and 34 blue LEDs (430-470nm) that target the chlorophyll absorption peaks. Red light promotes flowering and fruiting, while blue light encourages vegetative growth and strong stems. Together, they can help increase your yields and speed up growth cycles.

Perfect for indoor herb gardens, seedlings, succulents, flowers, or any houseplants that need extra light during dark winters or in rooms with limited windows. The aluminum body helps dissipate heat efficiently, and with a 50,000-hour lifespan, this bulb will last for years of continuous use. Whether you're growing microgreens in your kitchen, starting seedlings for your garden, or keeping tropical plants happy in a dim apartment, this grow light gives your plants the artificial sunshine they need to flourish indoors year-round.
