LEEF Light Packages

LEEF Light Packages allow students to make measurements of the radiant energy that plants use for photosynthesis—in the region of the electromagnetic spectrum from 400-700 nm. Plant scientists, horticulturists, ecologists, and other environmental scientists use LI-COR quantum sensors to accurately measure radiation in this range, known as Photosynthetically Active Radiation (PAR).

Both LEEF Light Packages (underwater and terrestrial) include a LI-1500 Light Sensor Logger with GPS and three input ports. When sensors are connected to the logger, data can be logged at predetermined time intervals. Instantaneous readings can also be viewed on the display screen.

LI-COR light sensors have been a research standard for more than 40 years, with more than 150,000 sold. Experience, attention to detail, and an advanced knowledge of optical science separate LI-COR sensors from other alternatives. Learn more at LI COR’s light sensor product page.

Applications

The LI-190R Quantum Sensor, included in both the terrestrial and underwater LEEF packages, is used for:

  • Plant science, biology, and earth science
  • Micrometeorology research
  • Greenhouse management
  • Agricultural and horticultural productivity studies

The LI-193 Spherical Underwater Quantum Sensor, included in the LEEF Underwater Light Package, is ideal for aquatic studies such as:

  • Aquaculture
