Our gardens use LED light bulbs that are very long-lasting - if used every day, the bulb should last for 7 years.
The Smart Garden 9, the Wall Farm, and the Click & Grow 25 have two types of bulbs - white and red LEDs. The red light spectrum will make the photosynthesis process more efficient, resulting in better growth and healthier plants.
The lamp can be pretty bright, but please avoid covering the garden to prevent overheating or causing a fire hazard. As all of our Smart Gardens use LEDs, you don’t need to worry about the lamp emitting any UV rays either so covering is definitely not needed.
