| abstract |
The present invention provides methods and materials for culturing and/or propagating photosynthetic organisms. These methods use a lamp assembly, the lamp assembly comprising a plurality of circuit boards; and a barrier surrounding a plurality of circuit boards defining a substantially spherical shape, each of the circuit boards including at least three corners, arranged in a substantially spherical shape defining an interior lamp assembly volume, the plurality of The circuit boards are comprised of a first planar surface facing the interior lamp assembly volume and an opposite second planar surface containing a light emitting diode (LED). |
