LI-COR Environmental

Large Light Source

The Large Light Source (6800-03) provides irradiance with any combination of red, green, blue, and white light (up to 2400, 1000, 2000, and 1500 µmol m^-2 s^-1 respectively). It features a precision reflector to provide highly uniform lighting of the leaf surface. An integrated silicon photodiode measures PAR above the leaf to provide real-time measurements of irradiance in the chamber. The Large Light Source is compatible with the Large Leaf and Needle Chamber, the Small Plant Chamber, and the Bryophyte Chamber.
