Fluorescent lighting is most suitable for plants that require low to medium light intensity.


  • Relatively low cost
  • Most readily available
  • Well studied for over 50 years
  • Provides white light in various color ranges
  • Uses less energy than incandescent lighting
  • Dimmable
  • Color-specific peaks can be obtained with special gas mixtures


  • Performance typically degrades after the first 1,000 hours of light uniformity, which can cause inconsistent research results
  • Bulbs must be recycled or disposed of properly and with special care
  • Bulb performance degrades at both the lower and higher operating temperatures
  • As bulbs age, they discolor and provide light in a less uniform manner
