To determine of suitable artificial light source for laver culture, 4 types of arc lamp, e. g. white fluorescent lamp, high pressure mercury lamp, thallium mercury lamp and metal-halide lamp were examined. According to the resuls of culture test of germlings or laver thallus in a vessel equipped the test lamp, the most suitable lamp was selected with the respect to the growth rate, thallus color and contamination by the other algae under the same light intensity. The results were as follows. (1) In the culutre illuminated with the thallium mercury lamp laver thallus showed high gorwth rate, dark greenish color and contaminants did not occur, in consequence thallium mercury lamp was the most suitable one for laver culutre. (2) In the cluture illuminated with the fluorescent lamp, high pressure mercury lamp and metal-hiald lamp laver thallus showed reddish black in color and much contaminants occurred. (3) Metal-halide lamp was considered to have an advantage of the highest energy effciency.
