To save electricity cost for tissue culture laboratory, fluorescent lamps 36 watt (T8) with conventional solid-ballast and 28 watt (T5) with electronic ballast set installed on the culture shelf were investigated. The intensity and light colors, daylight, cool white and warm white were examined on growth of in vitro plantlets of rose-colored leadwort and gloxinia. The results indicated that T5 lamps with electronic ballast set consumed electricity by 26.66 percent of T8 lamps, resulted in lower light intensity generated capacity. The combination of T5 and T8 cool white lamps on shelf gave the similar light intensity but cost ca 38 percent of energy less than T8 daylight. In addition, the growths of both plantlets culture under all type of lamps were non-significantly different.
